Kate Gregory's Blog - Windows 7

C++ AMP - I like it so much, I'm doing a book on it!

Kate Gregory — Thu, 09 Feb 2012 01:48:48 GMT

I've been excited about C++ AMP since it was first announced back in June. What's C++ AMP? It stands for Accelerated Massive Parallelism and it's about harnessing thousands of cores on accelerators like GPUs. You can speed up some applications by a factor of 10 or more. Not 10%, 10x. And you don't have to learn some C-like language, you get to work in C++. It's done almost entirely with libraries, which means you can use C++ AMP from a variety of applications, including Metro apps for Windows 8.

If you check my Concurrency category you'll see I've been writing code (and words) for months now. I just haven't been putting those words here on my blog. Instead, they're going into a book, for Microsoft Press! Soon, I will have some chapter drafts available for review. If you're interested, I've set up a page with some details, and some links for those who want to learn more.

There's increasing media coverage, including Peter Bright at ars technica and Darryl Taft at eWeek, and last week the spec was released to the public under the Microsoft Community Promise license. This means other compiler vendors can implement C++ AMP in their own compilers, allowing even more developers access to heterogeneous hardware and massive speedups for data parallel calculations. Herb Sutter mentioned it in the Day 2 keynote at GoingNative, the Visual C++ Blog included a link, and Soma blogged about it too.

Dive in! There's a lot to learn. And plenty of samples to play with. I'll post updates here as I go.

Tech Ed USA - Recordings

Kate Gregory — Fri, 29 Jul 2011 21:51:36 GMT

Since Tech Ed came and went during my blogging hiatus, I didn't get around to providing links to some of the sessions you might want to see. It's time to correct that omission:

WOMEN IN TECHNOLOGY LUNCHEON - Developing a Strong Support Network: The Key to Being Successful as Women in Technology
ALM for C++ in Microsoft Visual Studio 2010 - one of the highest rated sessions in the whole conference. C++ sessions get high ratings!
Advanced Programming Patterns for Windows 7 - my Day 2 session - no C++ content
Modern Native C++ Development for Maximum Productivity - my Day 4 session - plenty of native code here: lambdas, auto, the PPL, and so on.

There were other sessions I attended, including a great interactive session that was not recorded called "C++ Renaissance at Microsoft: How the C++ Developers Can Get Involved" with plenty of conversation between Microsoft people and native developers. You might want to do a little searching on the main Tech Ed Video site to see what interests you.

Developing for Windows in C++

Kate Gregory — Sat, 23 Jul 2011 04:39:47 GMT

So, you're a C++ programmer? You've written a Windows app or two in your time? Let me propose a little challenge to you. Write one. Only start with File, New and don't let Visual Studio generate any code for you. Write each line of it. Then explain it. No MFC, No ATL. That's what was asked of me a while back, and the result is a six-paper series that has finally arrived on MSDN.

I have to say I really enjoyed the simplicity of the smallest Windows program possible. I also enjoyed making it better, which included making it more of a C++ program and less of a C one. I also covered a little Direct2D, a little COM, and a little "here's some other stuff you're going to want to read." If it's been ages since you wrote a Windows program in C++, or wrote one that wasn't all covered in barnacles from frameworks and libraries you might not want to rely on for simple things, I really suggest you give this series a read - it won't take long and you can use Visual C++ Express if you like - the first chapter includes links and instructions for getting all the tools you need. Better still, if you've never written a Windows in C++, why not give it a try and let me know what you think?

ps: Never blog that you're not blogging. Never blog about why you're not blogging, no-one cares. Just blog. Right?

Trigger Started Services - Screencast and Recipe

Kate Gregory — Tue, 29 Mar 2011 12:31:10 GMT

The fourth of my Windows 7 development screencasts - Trigger Started Services - has been published. It uses the recipe (also recently published on Code Gallery) to simplify writing a service in managed code that starts only when it is notified by the operating system of a particular trigger. In my screencast I use the example of a USB device being plugged in. There are plenty of other triggers you could use. Adopting a trigger-started approach makes your service:

easier to write and install. No sleeping, looping, having a config file to say how long to sleep for, etc.
use less CPU when there's nothing to do
respond more quickly when there's something to do. It's not in the middle of sleeping for 10 minutes or 2 hours -- it is started the moment the trigger happens.

It's a win all around and if you have a service you should take a look at the available triggers and see if you can convert yours.

Restart and Recovery Recipes

Kate Gregory — Sun, 27 Mar 2011 12:21:53 GMT

The screencasts for restart and recovery in native and managed code went live before the associated recipe was published. Now the recipe is on Code Gallery ready for you to use. As it says there:

This recipe provides guidance and an easy way to start using these great features in your application, removing any complication of how and where to store your application data.

What’s in the box?

This Restart and Recovery recipe includes:

Complete source code of the recipe and its samples

Managed .NET assembly

C++ header and class files to be included in your C++ application.

C#, and C++ test applications

Documentation

Give it a try, please!

Two more screencasts - Restart and Recovery

Kate Gregory — Fri, 18 Mar 2011 00:38:55 GMT

Here's another pair of screencasts to simplify your Windows 7 development. Both cover Restart and Recovery - one is for native developers and the other for managed. As the screencast intros say:

Application Recovery and Restart (ARR) technologies enable developers to customize an application's behavior when Windows Error Reporting(WER) terminates the application due to an unrecoverable error. For example, it enables an application to perform data recovery and cleanup operations such as capturing application state and releasing resources before termination. It also allows developers to specify that WER should automatically restart an application that it has terminated.

I hope they help you do the right thing when your application blows up or the machine reboots.

Windows 7 Recipe - Taskbar Single Instance

Kate Gregory — Wed, 16 Mar 2011 00:18:48 GMT

You know I blog here a lot about Windows 7 goodies including taskbar integration. One of the questions I get pretty often is how to use tasks to communicate with the running app, such as changing your status, sending a new email, that sort of thing. I mentioned in an aside on another post that this requires launching some other application that communicates with the first instance.

If you'd like to do that, it just got a little easier with the release of a "recipe" from Microsoft that packages up this concept and lets you use it with very little extra code. As it says on the Code Gallery page for the recipe:

This Taskbar Single Instance Recipe allows developers to easily develop applications that use "Messenger Like" tasks that change the state of the currently running instance, allowing it to react to incoming state-change notifications and act accordingly.

This Recipe includes:

Native (C++) and managed (.NET) Source code for the Single Instance library

Well documented native (C++) and managed (.NET) samples

Documentation

To compile and run the recipe and samples the following items are required:

Microsoft Visual Studio 2010

Windows 7 – Note that only the samples require Windows 7.

Yes, this recipe is actually two recipes - one native and one managed, and comes with whitepapers explaining how it's done. I mentioned this in my Tech Ed Europe talk on Advanced Windows 7 development and it's finally released for you to use! Enjoy!

My screencast - Windows 7 Taskbar Integration with MFC

Kate Gregory — Sun, 13 Mar 2011 23:58:23 GMT

Whenever new stuff appears in the Microsoft universe, native C++ developers can get to it first. That's because they can easily call Windows APIs or COM interfaces or however it's implemented. Managed developers need to wait until the new stuff gets added to the .NET Framework or to a particular managed technology, like WPF. Take taskbar integration, for example: adding tasks and destinations, getting a progress bar or icon overlay on your taskbar icon, and so on. From the very beginning you could interact with the taskbar from native code by making Windows API calls. The Code Pack is a popular managed wrapper from Microsoft that enables those interactions from managed code such as Windows Forms applications. In the early days of Windows 7, WPF developers also used the Code Pack - but now those capabilities are in WPF itself.

Does that mean that native developers get nothing new? On release day they gain the ability to call those APIs and that's that? Of course not. Native developers use frameworks and libraries to build their applications, and those frameworks and libraries in many cases are wrappers for Windows functionality. One of those is MFC and you should know that MFC has support for Windows 7 functionality.

If that's news to you, then watch my screencast on Channel 9 in which I cover jumplists and overlays with lots of demos. It's just one or two lines of code for each of these. Users expect their apps to behave like this. MFC makes it simple.

Fun WPF Sample - Tasks.Show

Kate Gregory — Fri, 11 Mar 2011 15:31:40 GMT

Writing samples and demos is tough. You want them to do more than say "Hello World" or draw a red square, but you want them to be simple enough that people can see the "new stuff" you're demoing (WPF, or Windows 7 taskbar integration) or multi-touch) in amongst the real business logic. It would be neat if they did something actually useful, because then you might keep it around on your machine and use it, but most things that are useful are too big to be demos.

Well here's a sample that lands in the sweet spot: Tasks.Show. You put in your tasks, things from your ToDo list, along with time estimates, and it keeps track of them and shows them to you. I like this view:

It uses touch to let you flick tasks into categories, and has taskbar integration to let you open a specific category, add a task, and so on. All the source code is available so you can see how it's done - it is a demo, after all. You can get more details and screen shots on the Windows Team Blog. Check it out!

My Tech Ed Atlanta Sessions

Kate Gregory — Thu, 10 Mar 2011 02:42:23 GMT

I have two sessions in Atlanta:

DEV303 | Modern Native C++ Development for Maximum Productivity

Breakout Session | 300 - Advanced | Developer Tools, Languages & Frameworks

C++0x, the next C++ standard, is almost upon us and it contains the most important updates to the language since the mid-90s. These new features bring more expressiveness and power to the native C++ developer. Microsoft Visual Studio 2010 has added support for some of these key features in order to enable these modern programming techniques. This session clarifies what features are in Microsoft Visual C++ 2010 and what is yet to come. It illustrates how new constructs such as lambda expressions enable better use of existing libraries and how your code can be simpler, safer and faster all at the same time. Also, see how simple it can be to implement concurrency in your application and how Visual C++ 2010 supports the difficult task of debugging parallelized code. If you are itching to show off how C++ is one of the coolest languages on the planet, this talk is for you!

DEV304 | Advanced Programming Patterns for Windows 7

Breakout Session | 300 - Advanced | Developer Tools, Languages & Frameworks

Windows 7 development in managed code can be very simple, especially for those using the Windows API Code Pack. But there's more! Your integration with Windows 7 doesn't have to be limited to simple interactions with the new API. This session goes beyond the simple and into aspects of Windows 7 development that have in the past been left for you to explore on your own. See how to create a jumplist with a task that delivers a command to your application, as Messenger and Outlook do. Explore a simple and powerful recipe for connecting to Restart and Recovery with minimal effort. Discover how Trigger Started Services can reduce your power footprint while giving your users better responsiveness. Explore all that libraries have to offer beyond "File Open" and why using a library is a better approach than having a user setting for "save directory."

I'm looking forward to it. If you haven't registered yet, you should!

Fun Windows 7 demo now on your phone and in your browser

Kate Gregory — Sat, 19 Feb 2011 22:53:09 GMT

Imagine an app that you have running under Windows 7 as a desktop app. Now as much as you are enjoying the Windows 7 features it uses, you know there is some functionality there you could offer to people another way. Do you have to just start over to make it into a phone app? What if you want it in a browser? If you write the desktop part in WPF, will that be something you can use when you create the Silverlight code for the browser or phone apps? Well, check this mission statement:

Our goal was to enable seamless and easy sharing of decks among users across different computers. The idea was simple, upload the deck to the cloud, and let the user send a message to whomever the user wants to share the deck with. That message will include a link for the receiving party to click on to launch a web browser and run a Silverlight application that can “play” the shared deck. The Silverlight application dynamically downloads the shared deck and displays that single deck just as it would be displayed on the WPF application. At this point the user can launch any of the 3 games: Learning, Matching, or Memory, with the same user experience as the WPF application.

Sounds like just what you might like to do in some of your apps, doesn't it? Oh yeah, and would you like the code? And a blog post explaining the code? And a video on Channel 9?

Happy to help!

More Good stuff happening with All-In-One Code Framework

Kate Gregory — Wed, 09 Feb 2011 16:41:05 GMT

At the end of January, the busy bees at All-in-One (OK, they're not bees, they're Microsoft engineers) released even more samples including Azure, setting a hotkey that Windows will route to your app even if it doesn't have focus, detecting if the machine has been locked (with Windows+L) or unlocked, downloading multiple files with ftp, and many more. As always these are in VB, C#, and almost all of them are also in native C++.

In fact, there are just so darn many samples right now that it's getting harder to find the one you want. What a great problem to have! So they've released a sample browser to help you search and browse and generally get your hands on the code that will solve your problem and move you on to the next part of your day.

What are you waiting for? Go get it!

Building SDK samples without Visual Studio

Kate Gregory — Wed, 26 Jan 2011 23:25:57 GMT

Not everyone knows that the Windows SDK includes a C++ compiler and linker that you can use if you don't have Visual Studio installed. Of course, Visual Studio Express is free, and you could use that to compile and link C++ apps. The advantage of using the tools that come with the SDK is that you don't have to install and configure a lot of stuff to get started. On a new machine that may appeal to you.

Gus Class has posted a super-quick 3 minute video that shows how to compile one of the SDK samples using only the tools that come with it. I just wanted to elaborate on one thing. The SDK installs, by default, under Program Files. As you probably know UAC prevents applications from writing to any folder under Program Files unless the application is elevated. That's why Gus launches an elevated command prompt in this video. If you don't want to elevate your command prompt, you'll need to move the sample folders and adjust your path accordingly.

Three minutes. Worth a watch. It's always good to have some tricks up your sleeve on a new machine.

Tech Ed North America Session Preferences

Kate Gregory — Sat, 08 Jan 2011 15:14:11 GMT

The voting is open at the Tech Ed site for you to express your preferences on possible sessions. My experience indicates that submissions not shown here can still end up being sessions, and certainly not all submissions shown here will be accepted, but obviously a strong interest from the public in a session will increase its chances of acceptance. With that in mind I thought I'd show you the results of a few searches.

First, C++:

These have orange plusses on them because I've added them to my preferences. You'll see a grey square you can click to add them to yours.

Next, Windows 7 development. Let's try Code Pack:

And finally the intersection of WPF and Windows 7 searches (I had to crop the shot by hand, there's no handy search that returns just these):

If you want to be sure that Tech Ed USA offers sessions you'd like to attend, the power is in your hands. (Disclaimer: some - but not all - of the submissions I am showing you here are my own.) Make your feelings known. And see you in Atlanta (I hope) in May!

Speaking at DevTeach - Advanced Windows 7 Programming

Kate Gregory — Sun, 02 Jan 2011 16:00:29 GMT

The sessions have been selected for DevTeach and I was pleased to see one of mine accepted. I'll do my "Advanced Windows 7 Programming" session:

Windows 7 development in managed code can be very simple, especially for those using the Windows API Code Pack. But there's more! Your integration with Windows 7 doesn't have to be limited to simple interactions with the new API. This session goes beyond the simple and into aspects of Windows 7 development that have in the past been left for you to explore on your own. See how to create a jumplist with a task that delivers a command to your application, as Messenger and Outlook do. Explore a simple and powerful recipe for connecting to Restart and Recovery with minimal effort. Discover how Trigger Started Services can reduce your power footprint while giving your users better responsiveness. Explore all that Libraries has to offer beyond "File Open" and why using a library is a better approach than having a user setting for "save directory."

This is all managed code, C# and VB. The conference is after Tech Ed US this year, (Tech Ed is May 16-19, DevTeach is May 30 - June 3) so rather than you seeing a Tech Ed talk before the Tech Ed attendees do (my usual DevTeach offer) you can see a Tech Ed talk after it's been refined a bit by giving it to a Tech Ed audience. Even better!

Montreal in the early summer is a beautiful place and there's a great crop of speakers coming! Many are friends, all are top-notch. Sign up now for only $899 Canadian for the full 3 days! That's less than half the price of Tech Ed, and you travel only to Montreal. If you're a developer, give this conference serious attention. Of course, if you can do both Tech Ed and DevTeach, you will gain maximum benefit and a chance to learn all that is current in our field. That's my May 2011 plan.

Another "no jumplist" reason

Kate Gregory — Sun, 26 Dec 2010 00:40:06 GMT

A while back, I blogged about an empty jumplist for Windows Explorer and how I fixed it. I've come across another no-jumplist issue, this time in a blog post by Rick Strahl. This app never gets a jumplist, and can't be pinned to the taskbar or start menu either. Believe it or not, the reason is the executable name. I've seen all sorts of people running into issues with UAC elevation being triggered by certain executable names, but this is the first I've heard of the jumplist being taken away because of it.

Rick looked into it, found the documentation, even found the Registry key and the list of "magic" words in your executable name (Documentation;Help;Install;More Info;Readme;Read me;Read First;Setup;Support;What's New;Remove) that cause the problem. Nice work! Your options, if you find yourself here, are to rename your exe, or (if, like Rick, you have a lot of stuff depending on that name thanks to COM etc) to change the Registry key so that whatever string you're using isn't the problem.

More Samples from the All in One Code Framework

Kate Gregory — Wed, 15 Dec 2010 15:57:52 GMT

Those hardworking elves at the All in One Code Framework keep releasing more samples. They've added some ASP.NET samples (including a very interesting "get location from IP address" one) and some Windows 7 shell extensions, specifically a preview handler. Ah, the good old .recipe file type - an old friend of mine. But as always the samples are going to save you hours and hours of time.

Here's an index to all the samples for you to explore. You might be a little astonished if you haven't checked it out before, they have:

Slowly but surely the samples are accumulating to live up to the name. This should be the first place you look when you want to take on a new task. Generally speaking, everything is available in native C++, C#, and VB (the exceptions are things you can't do in native C++, like ASP.NET) with the language included in the sample name (look at CppWin7TriggerStartService, CSWin7TriggerStartService, and VBWin7TriggerStartService for example.) And remember, if you don't see what you want - you can ask for it!

Windows Development Bootcamps - free day of training

Kate Gregory — Mon, 13 Dec 2010 15:40:52 GMT

At the moment these are announced in the USA only. A full day of client development training for Windows 7, including IE9 and SL OOB. They say:

We will look at application compatibility and transitioning your applications to Windows 7, integrating with the Windows taskbar, developing for IE9, utilizing the cool functionality in the Sensors and Location Platform so that your application better responds to its current environment, leveraging the multitouch capabilities (especially in kiosk scenarios), and creating Silverlight 4 out of browser applications. This event is a unique opportunity, partnering classroom learning with hands-on-labs and leveraging experts to advise you so we can help you “win” with Windows 7.

You bring your own laptop with VS 2010, the Code Pack, the Windows 7 Training Kit, IE9, and Silverlight 4 installed (there are links on the bootcamp page) and do the labs as you go. The training is all free and you'll get hands on experience right while you're there. (It doesn't say so, but my guess is this is all managed code and that the labs are in both C# and VB.)

And if there isn't one near you, you can help arrange one! It's all packaged as an event-in-a-box so all you need is a trainer who'll agree to deliver it and a room to hold it in. But check the dates and locations first -- there are over a dozen sessions scheduled already, so perhaps there's one near you.

Getting to Windows 7 Functionality from Silverlight

Kate Gregory — Tue, 07 Dec 2010 17:33:24 GMT

Windows 7 developers have tons of cool stuff at their (our) fingertips. There's taskbar integration, the new sensors and location platform, access to devices, and more. Silverlight developers, on the other hand, have so far not been able to get to all of that. Well, now you can! The Native Extensions for Microsoft Silverlight leverages the ability of Silverlight to do COM integration, and puts COM Automation around a collection of Windows 7 functionality so that Silverlight developers can use it. How cool is that?

Because it's on the Code Gallery, you know it's from Microsoft. The first release, Dec 2nd, covers:

Windows Sensor API - Integrate sensors: Accelerometers, Light sensors, compasses, gyroscopes etc.
Microsoft Speech API - Text to Speech (Speech Synthesis) and Speech to Text (Speech Recognition)
Windows Portable Devices API - Enumerate and access content from connected portable devices (cameras, phones, music players, scanners etc.)
Windows 7 Taskbar Integration - Jump lists, overlay icons, overlay progress display, Thumbnail toolbars etc.
Webcam Local Encoding and Window Capture - Encode webcam capture into mp4 (H.264/AAC-LC) media - Capture user interface interaction as video
Window Message Interception - Intercept and act on Window messages sent to the Silverlight OOB host window

This certainly gives Silverlight developers some interesting options! There are some samples that come with the library to show you what you can do, too. You might also be interested in Maor David's blog entry about the library.

Resetting a jumplist

Kate Gregory — Thu, 25 Nov 2010 18:42:06 GMT

You know I just love jumplists. Probably my favourite app to have a jumplist is Windows Explorer. After all for Word, PowerPoint, Visual Studio and so on, there is a MRU list on the file menu or the like. But getting to folders I've used recently is super important to me.

That's why I kind of freaked out when the jumplist for my Windows Explorer disappeared.

I tried rebooting my laptop (something I do less than once a week.) No help. I caught up on updates. No help. So I started searching. And I found two articles, one about a jumplist that is slow to load itself, and other other about an "orphaned" item that couldn't be removed from a jumplist. That one helped me realize the likely cause of my problem - although I hadn't pinned a mapped folder, I had mapped a drive at a client site, and now that drive wasn't accessible any more, which is perhaps why the jumplist wasn't loading.

But anyway, what to do? Based on what I read in those two articles, I navigated to %APPDATA%\Microsoft\Windows\Recent\AutomaticDestinations (that's exactly what I typed into the Run box, it figures out %APPDATA% for you.) There I saw a whole pile of apps with a strange extension, a little reminiscent of the files that hold the details for libraries:

If you open any of these files in Notepad, you'll see that amongst all kinds of unintelligible strings are paths to files you've dealt with recently. What's more, you can kind of guess which app each file is for by looking at those paths - one file will have a bunch of .pptx files mentioned in it, while another will have a bunch of .xlsx files. Now, which one is Windows Explorer?

Well, both articles said the same name: 1b4dd67f29cb1962.automaticDestinations-ms.I had a file called that, and when I browsed in Windows Explorer to another folder, the timestamp on that file changed. It seemed quite sure that it was for Windows Explorer on my machine too. So, I deleted it, as the articles suggested. Now I still had no jumplist, but when I then browsed to another folder, I had a jumplist with one item in it. From then on life was back to normal.

Something to know if you get a stuck jumplist someday.

Windows 7 - tasks vs thumbnail buttons

Kate Gregory — Tue, 23 Nov 2010 20:38:40 GMT

Windows 7 introduced a lot of new ways for an application to give information to users. There's a thumbnail which is usually a miniaturized version of the whole application, and possible overlays of icons onto your taskbar icon (like how Outlook shows you have new messages, or Twitter shows there are new tweets) and progress bars under your taskbar icon. There are also cool ways for the user to give direction to or about the application. For example, you can right-click the taskbar to bring up a jumplist and launch another copy of the application, or another application.

Right from the beginning, some applications pushed that architecture a bit to use the jumplist to communicate with the application itself. (This requires launching some other application that communicates with the first instance.) For example, Outlook has this jumplist:

But this isn't the only way to send a command to an application from the taskbar, and it's not always the right one. Tasks are the right choice if you're willing to take on the extra work to code them up, and furthermore if they make sense even when the app isn't running yet. So in this example, Outlook, if I want to send a new message then I want to send a new message, even if that means needing to launch Outlook to do so. But what about Messenger? Here's how it used to look:

Does that make sense when Messenger isn't even running? To me, it doesn't. Here's how Messenger handles that now. There's a much smaller jumplist:

How do you set your status? With thumbnail toolbar buttons:

Sweet! Much easier to code, easy for the users to understand, and they don't clutter up the place when the app is not running. Nice decision. And keep this in mind for your own Windows 7 applications.

Get publicity for your Windows 7 app

Kate Gregory — Wed, 17 Nov 2010 21:43:15 GMT

I like to say "If you have a Windows application, it should be a Windows 7 application." By that I mean that you should take advantage of some of the features Windows 7 offers to your apps, and you should give the user the experiences they are coming to expect on Windows 7. You should have a sensible and usable jumplist. If you have a progress bar, you should add ONE WHOLE LINE OF CODE to your app so that progress bar is also overlayed on the taskbar. You should toss your intrusive message boxes and toasts and system tray balloons and use taskbar icon overlays on Windows 7, because that's how users expect to be notified about non emergencies. You should take advantage of restart and recovery, and of being notified about events like going on battery or AC power, or coming online or offline, instead of expensively polling for them. I've written a lot of blog posts and given a lot of presentations on how to do some of those things.

Now, someone is offering you a reward for putting those capabilities into your Windows applications. You can be featured on CNET Downloads if you just submit an application that uses at least one of the 13 features they identify. If your app is ready to go, submit it today! If not, why not?

Tech Ed Videos are Up

Kate Gregory — Sat, 13 Nov 2010 13:41:15 GMT

Wow, these things get up there fast! My sessions were very well received and I had such a great time doing them! In the order I delivered them, they are:

Women In Technology Panel - Claudia Woods, Freena Eijffinger, Paula Januszkiewicz, and Rhonda Layfield joined me to take questions from the audience and talk about what was on everyone's mind. There's really no video - just the title slide for the whole hour. Please listen!
The Windows API Code Pack: Add Windows 7 Features to Your Application - This one includes screen capture so you can follow along in the demos. You can also download the powerpoints from this page, and as I mention in the talk, the demo code is the samples that come with the Code Pack.
Modern Programming with C++0x in Microsoft Visual C++ 2010 - I had a great time delivering this talk even though it was the first time I delivered this version of it. The attendees responded by putting the talk in the top ten for the whole conference - thankyou! It, too captures the screen and slides, and you can download the powerpoints.
Advanced Programming Patterns for Windows 7 - Another talk I was doing for the first time and I enjoyed it too. If you'd like the sample code, stay tuned - I will blog when the recipes are released. The slides are with the video of the screen and slides.

If you came in person, thank you! If you couldn't be there, please watch the videos and leave me a comment. Speaking on technical topics really is the most fun you can have standing up, and I can't do it without audiences.

User Group Leaders: great Pluralsight offer

Kate Gregory — Thu, 11 Nov 2010 13:20:15 GMT

Pluralsight has some great offers for user group leaders that you should really know about. Even if you don't lead a group, make sure your leader knows, because some of these offers are for members. They're offering to send swag, subscriptions, and speakers (oh yes, that could include me, it sure couldn't hurt to ask, right?) to groups. What's more, unemployed user group members can have a free one-month subscription to the Pluralsight On-Demand! library - a fantastic all-you-can-eat way to get your skills modernized and get you back working again.

I wrote Windows 7 and Visual Studio Extensions courses for the library, and am working on plans for my next one. These are great people who really want everyone to learn as much as humanly possible, and work hard to make that happen. Take them up on this offer and you won't regret it!

Want to prove your Windows app makes the grade?

Kate Gregory — Sun, 07 Nov 2010 12:57:05 GMT

Let's say you've written a great client (that is, not web) application. Perhaps you've added some specific features to make it great on Windows 7. Certainly you've made sure it runs on Windows 7. Or perhaps on Windows Server 2008 R2. Or maybe your app runs on Windows Azure, or Windows Phone 7. Good work! You put time and effort into confirming that your app fits your chosen platform. Now, would you like to be able to prove it with a suite of automated tests and a logo that shows you passed them? Of course you would.

So head on over to Microsoft Platform Ready and take a look around. You'll find training resources to help you build applications that target Windows 7, Windows Server 2008 R2, and Windows Azure. You can test your app and get logos like Powered by Windows Azure and Works with Windows Server 2008 R2.You can even showcase your application in a marketplace, and take advantage of special offers like extended trials of developer tools from various partners.

This is an obvious step for anyone building a client application, on any part of the Microsoft platform. Investigate, join, reap the rewards :-).

Coffee and Code in Montreal, Mississauga and Ottawa

Kate Gregory — Fri, 05 Nov 2010 16:10:46 GMT

You may have noticed that the fall tour I'm doing features morning talks that go till about 11:30, and evening talks that start at 6pm. I've decided that between those two, I'll spend the afternoon in a coffee shop and host an "on the road coffee and code". As I explain on the Coffee and Code page I keep for this purpose, this is really informal. Just stop by, say hi, we can talk about whatever you like. If you were at the morning session, you might want to just walk with me from the venue to the coffee shop and continue the conversation. Or if you're coming to the evening session, you might want to try to find me during the afternoon to ask something specific, then head to the venue together. Or maybe you have a topic to discuss that has nothing to do with Building Awesome Windows 7 Applications in managed code: a C++ question, or an extending Visual Studio 2010 question, or whatever. That's great, and the Coffee and Code format is just the place for us to have that chat.

If you live or work near the venues for the fall tour, I'd appreciate your suggestions (by email or twitter) for where to hold these. Obviously we need wifi, power, and a table we can hog for most of the day. My default choice is Starbucks, but if you know a better one that I can easily walk to, please tell me about it. Once I've chosen the location I can finalize the times.

Looking forward to meeting everyone,

Kate

Next, descriptions - what are we going to do? We're going to make you better Windows 7 developers, that's what. We'll do some Code Pack coverage (sure, jumplists, taskbar stuff, but beyond that - some of the material from my Advanced Windows 7 Development at Tech Ed Europe will get its Canadian debut) and then dive into touch development. There are abstracts in John's blog post.

If you can't get to one of those cities on the appropriate day, never fear - there will be a webcast, too. Please spread the word about the webcast throughout North America, everyone's welcome!

I'm looking forward to this tremendously!

Get Microsoft to write you a code sample (really)

Kate Gregory — Mon, 01 Nov 2010 15:40:23 GMT

Here's something that happens to me a lot. I'm working on a project that is mostly Technology A, but I need a little Technology B. I want a sample or two to show me what it can do. I search the web, but often find mostly things written by people who don't know what they're doing and are posting their (possibly flawed) code into question-and-answer forums. I search MSDN, but often the newest technologies don't have their samples yet. I also remember to check if the All-in-One Framework people (I blogged about their coding standards document earlier) have anything. And if I still get nowhere I start asking people I know if they have one.

Well, now those helpful folks at All-in-One are kicking it up a notch. And remember, they cover all technologies and languages related to Microsoft tools. (Want to know more about them? Here's a fun video.)

And this goes back to one of my earliest blog posts - what you want may be what I need to give. Imagine it's your job to decide what samples to write. How are you ever going to find out what developers out in the big wide world want samples of? You could come up with a great idea and then find out people already had all the samples they needed for that. So that person wants ideas for samples. And here you are needing a sample. See how that works?

Just visit the wiki page and follow their instructions. It's a tad more complex than "shoot me an email and tell me what you need" and for good reason. Give it a whirl if there's something you need!

Hilo Uploader - Photos to Flickr with WWSAPI

Kate Gregory — Sun, 24 Oct 2010 18:23:59 GMT

Hilo, the reference application project from the C++ team that doesn't use MFC or the .NET Framework, is back with another sample. You've seen nice graphics in the way photos are treated, a ribbon UI, and now you can see social media integration with Flickr uploads, touch support, and Windows 7 jumplist support. And remember, all the code is available for you to explore and learn from.

Take a look and see what you think. If you want to know how to build a modern UI and a modern set of functionalities (like web services) then this is the reference application for you.

Great roundup of Windows 7 developer resources

Kate Gregory — Sat, 16 Oct 2010 17:07:42 GMT

Jennifer Marsman has built a very nice list of Windows 7 developer resources. Of course, she had me at Code Pack (the very first item she lists as a matter of fact), but she carries on, drilling into both native and managed scenarios, covering libraries, SDKs, training materials, UX guidelines, samples, blogs - even Twitter handles!

There is a LOT of material out there and it's a little bit fragmented. This is a great post to help you find your way around. Remember, if you have a Windows app, it should be a Windows 7 app!

My Tech Ed Europe Sessions - Up to Three Now

Kate Gregory — Wed, 06 Oct 2010 21:38:21 GMT

The Tech Ed Europe Session Catalog has been updated with my third talk. In the order they're happening, I have:

WCL322 - The Windows API Code Pack: Add Windows 7 Features to Your Application

DEV311 - Modern Programming with C++0x in Microsoft Visual C++ 2010

WCL329 - Advanced Programming Patterns for Windows 7

The first two I blogged earlier, but the third is new. Here's the abstract:

Windows 7 development in managed code can be very simple, especially for those using the Windows API Code Pack. But your integration with Windows 7 doesn't have to be limited to simple interactions with the new API. This session goes beyond the simple into aspects of Windows 7 development that have, in the past, been left for you to explore on your own. See how to create a jump list with a task that delivers a command to your application, as Messenger and Outlook do. Explore a simple and powerful recipe for connecting to Restart and Recovery, with minimal effort. Discover how Trigger Started Services can reduce your power footprint, while giving your users better responsiveness. Explore all that Libraries has to offer beyond "File Open", and learn why using a library is a better approach than having a user setting for "save directory."

It's going to be a great week!

Kate

PS: About the fourth item you might see under my name ... stay tuned! :-)

Interesting job for the right person

Kate Gregory — Mon, 04 Oct 2010 21:29:10 GMT

I started paying attention to "app compat" around the time Vista was in beta. It stands for Application Compatibility and refers to all the various techniques for ensuring that an application continues to work when it's moved to a new environment, such as from XP to Vista or to Windows 7. Some of these techniques involve changing the source code of the application and rebuilding it, but others don't. And paradoxically, in order to be good at those no-writing-code techniques it helps if you're really a good developer. It really helps if you have strong skills in areas that the .NET Framework generally hides away or abstracts from you.

There are folks whose job it is to solve app compat problems. It's the kind of job that really appeals to me, where you aren't exactly sure how things are going to go each day when you get up, and you think on your feet and react to what you find. And now there's an opening to be such a person if that interests you. Aaron Margosis writes:

The job is basically to figure out why applications that are important to the customer and that work on earlier versions of Windows (typically running as admin) no longer work on Windows 7, and then to get the apps to work correctly without reducing security posture and (typically) without seeing or touching source code. Don’t worry – we will teach you the tricks.If you enjoy problem solving on the Windows platform, you will love this job.

Interested? Have some experience writing Windows apps in native C++ or C? Know a little about how Windows works? Think that being handed unknown problems and asked to fix them is more fun than a regular job? Then read the blog post and apply!

Mark Relph on Dot Net Rocks

Kate Gregory — Sat, 02 Oct 2010 21:20:01 GMT

As a Canadian RD, MVP, speaker, and general involved-in-the-developer-community-person, I interact a lot with the nice folks at Microsoft Canada. It's not unusual for Canadians to be transferred to Redmond to work at "the mother ship" and I tend to keep an eye on them in their new roles and watch what they're up to. That's even more likely when they go to an area that interests me, as Mark Relph did in the summer of 2009.

He appeared recently on Dot Net Rocks to talk about developing for Windows and I really enjoyed listening to the episode. I'm not the only one keeping an eye out, obviously, since John Bristowe blogged a nice summary of the episode with helpful links. Be sure to read that, then listen to the episode, then come on back for the links.

Add a jumplist to someone else's app

Kate Gregory — Thu, 30 Sep 2010 20:13:56 GMT

By now I'm quite addicted to jumplists. When I want to open a PowerPoint deck or a Word document, and I have another one of those open, I just right-click that instance, spot my document among the recent documents, and click it to open what I want. It frees me from remembering exactly where documents are, or opening folders just to open documents they contain, and I like it a lot. I also like the tasks lists that more and more applications are adding, like these:

But older apps have so much less to offer:

What if you could add tasks to the jumplist of any application, without needing access to the source code? That's what Jumplist Extender does. There's a nice review on How To Geek that demonstrates adding tasks to the calculator that comes with Windows.

Neat, isn't it? Get your own copy and have some fun.

Would you like a month to stuff your brain with the Pluralsight library - free?

Kate Gregory — Fri, 24 Sep 2010 20:29:08 GMT

I've mentioned the Pluralsight library many a time. I have three courses in it: Windows 7 development, Extending Visual Studio 2010 without writing code, and Extending Visual Studio 2010 with code. There are a variety of subscription plans available, each with their own benefits. But of all the possible prices you could pay, I'm betting that "free" is the one you would be happiest paying. Am I right?

Well, if you have an MSDN subscription, you can have a month of the Pluralsight library for free. That should give you a great idea of what the courses are like and what you can learn from them. Try it out!

Version 1.1 of the Windows API Code Pack

Kate Gregory — Mon, 20 Sep 2010 17:59:31 GMT

This release actually slipped out at the end of August with little fanfare. But you really should check in to it. First, if you're already a Code Pack user, you'll want the update for the bugfixes and related tweaks. If you're one of the people who looks at the source code to this useful library, for example for an interop reference, you're going to find it much improved. One really obvious thing is that all the samples are now happy to convert to VS 2010 which had been an issue for me with 1.0.1.

As well there are three new capabilities: Shell Object Watcher, Preview Handlers, and Thumbnail Handlers. Shell extensions used to be offlimits from managed code because they run in process with either the shell or whatever process launched them (which could be anybody's app that uses the Common File Dialogs) and you were forbidden (but not prevented) from using managed code in that situation. The issue was that if the launching process was already managed code and it had a different CLR loaded, then weird things would happen when your managed code wanted your own CLR. But now that restriction is lifted, so you can write preview handlers (which are out of process, so you were allowed to write them before) and thumbnail handlers (which are in process and therefore were native code only before) for your own file types. The Code Pack makes that pretty simple, all things considered.

Download it, install it, and if you have issues someone is reading and responding on the discussions tab, so please join the conversation.

DevTeach videos online - free

Kate Gregory — Tue, 14 Sep 2010 11:25:50 GMT

I love speaking at DevTeach. It's a must-do conference for a lot of A-list speakers and it's always fun and informative. I've blogged about it a lot already. Now Jean Rene has released the session videos online. So if you didn't get out to see us, you can still watch - how cool is that?

Scroll down the page till you see this:

Click on the title to watch the video, and on the Material link to get the powerpoints. (I recommend you watch these in the reverse order than they are shown - first Lighting Up, then Code Pack. Enjoy!

Hosting a Coffee and Code

Kate Gregory — Thu, 02 Sep 2010 14:18:01 GMT

I'm having a Coffee and Code of my own in downtown Toronto on September 23rd all afternoon. Actually, I'll start at 11 and be there until 6 to catch the "stop by after work" folks. If you've heard of Coffee and Code at all, you know how this works. If you haven't, I've made a page on our web site about it. Just drop in and ask me "Is it true that the C++ language is getting new keywords and stuff? How can that be? And does it really matter?" or "Do you have the Windows Phone 7 tools installed? Can you show me an app on the emulator?" or "Is Visual Studio 2010 really nicer than Visual Studio 2008?" or "What local user group meetings should I be coming to?" or whatever else is on your mind.

So stop by any time between 11 and 6 on the 23rd to the Starbucks at Yonge and King. I'll be at the big table at the back, just walk up and say hi. We'll talk about whatever is on your mind, maybe some of you will talk amongst yourselves, maybe you'll show me what you're working on. I'm looking forward to it!

Hilo Annotator

Kate Gregory — Wed, 25 Aug 2010 19:38:57 GMT

I mentioned Hilo when it was first released. This is a cool project doing Windows 7 development in native C++ with no frameworks - not MFC, for example - so you can really see just how it is done. It's not just code, it's also a walkthrough of their design thoughts, and explanation of that code.

The next application, Hilo Annotator, is ready. It features a ribbon, it uses the Windows Imaging Component, Direct2D, and so on. While you probably don't need an image annotator, you may find the code useful in your own applications. And remember, this is all native C++ code.

Your best place to start is the Visual C++ Team Blog entry about it. It's rich in links and has a nice screenshot too.

Visual Studio Add-in for Windows 7 Taskbar extras

Kate Gregory — Mon, 09 Aug 2010 13:43:37 GMT

Visual Studio 2010 has pretty cool Windows 7 integration. It gets jumplists right, for example:

But it could do more, and this little add-in adds some fun extras.

Here's a taskbar progress bar overlay during a build:

(If your build results in errors or warnings, you'll also get a taskbar icon overlay when it's done letting you know about them.)

And here we have handy thumbnail buttons - for build, debug, and start without debugging:

Give it a whirl! You can download it from the gallery, or use Tools, Extension Manager, Online Gallery right in Visual Studio and search for Taskbar.

Same machine, different OS, battery lasts longer

Kate Gregory — Thu, 22 Jul 2010 15:55:10 GMT

Would you like your machine to use up to 25% less power? Are you on XP now? You can see a big improvement by switching to Windows 7. There are some other things you can do too, like changing some drivers, but those are probably a bit difficult for most people. We have a number of machines kicking around the office that we've left on XP because they're really just file and print servers, people don't use them directly very often, so the obvious UI benefits of Windows 7 didn't seem relevant. But lowering the power bill is relevant, right? Or, if you're out and about with your laptop, having the battery last longer is relevant, right?

Here's the blog where I found some numbers ... it's a summary of a longer whitepaper and you should probably read that too.

Another PSOD Windows 7 Course

Kate Gregory — Sun, 18 Jul 2010 19:31:09 GMT

Pluralsight On-Demand! now has a second Windows 7 development course. I'm happy to see this - Eric and I co-ordinated while I was doing my course. In the first modules that are online now, he tackles topics that I did not - Restart and Recovery, Task Dialog, and Search. Feel free to use both courses to make yourself a better Windows developer!

Windows Summit sessions

Kate Gregory — Fri, 16 Jul 2010 17:46:01 GMT

I've had a chance to watch a number of the videos from the Windows Summit - an online event to help you with Windows development of all kinds. You can learn more about it and register at the main summit site, or check the lists of sessions for developers. The only trick is that once you've registered, you need to go to a different site to actually watch the sessions. Once you know that (and there is a link on the main site) you're all set.

I've been getting "Windows 7 for Developers" training since before the first public beta, so I had seen a lot of this before. But several sessions were noticeable improvements from the way that material had been covered in the past, and none of them were poorly done, so I recommend this as a way to learn the concepts that are important to anyone writing for Windows 7, and to learn the advantages that Windows 7 can offer to you as a developer and to your users.

I saw three different approaches to code in the sessions I watched:

Full on demos with Visual Studio involved
Code on the PowerPoint slides, and links to resources that include code demos
Mention the name of the API but don't show how to use it

I also saw a mix of native and managed code, with some sessions going all the way to the native side of the spectrum and some all the way to the managed side. Most of the sessions mentioned the Code Pack, of course, and call out a link to it in their resources.

Even if you know all about the taskbar, maybe you could learn about power management, or background services, using sensors, or writing location aware applications? It's really worth taking a look around.

Finding files you're sure you wrote

Kate Gregory — Wed, 14 Jul 2010 13:25:20 GMT

Here is something I've been asked more than once, and seen asked on various forums as well. I'll paraphrase rather than quote one specific asker:

We have an application written 15 years ago that's been working flawlessly. But when we run it on Windows 7, the users can't find the files it writes. Worse, there are no error messages, so they think they've saved the files, but when they go to C:\Program Files\MyGreatSoftware\UserExports - the files aren't there!

Often, the question trails off into a rant about how sneaky and mean Windows 7 is to somehow prevent access to Program Files but not give error messages. The rant might also include a paean to how amazing the lost files were and how many workyears of productivity have been lost now that these files cannot be found, and why this means you can't trust Windows to do something as simple as write a file to the hard drive. Sometimes, the asker has established that this is related to UAC and they are recommending everyone turn it off to avoid this disaster. I thought I would make some less drastic suggestions.

First, your files are not lost. A few people know this, but they then claim the files are almost impossible to find and no end user will ever find them. Let's tackle this one first because if you know this trick you may be able to get by without changing anything else about your application. Tell the user to go to the place they expect to find the files, say C:\Program Files\MyGreatSoftware\UserExports. Then have them look in the toolbar for a button that says Compatibility Files. Click it. Ta-da!

Ok, now the next thing is, why the heck are your files being written there? Because you are trying to write to a protected area and you don't have a manifest. You have several things you can do about this, and they boil down to two main things:

One, don't write to a protected area. You can get this by installing somewhere other than Program Files (not a good idea) or by changing the application to write to a better place. Two, get permission to write to the protected area. This means running as administrator. Train the users to right-click Run As Administrator when they run the app, or train them to set the Compatibility Settings for the app (neither very likely) or ship the application with a manifest that includes requireAdministrator. Now matter how you arrange this second thing, your users are not going to like agreeing to the UAC prompt every darn time. So really, that brings you back to number one, don't write to a protected area. Use AppData instead - there's a simple function call to get that path on any machine (including older XP machines) and you'll be in fine shape. If you think your users can't find that, and the files are for the users and not just some internal settings, then use a folder under Documents - again, there's a simple function call that will get you the path.

If virtualization makes you nuts - that your code thinks it's writing to C:\Program Files\whatever but really it's writing somewhere else, and the OS is cheerfully lying to it and saying all the writes succeeded - then put a manifest on your app. Doesn't matter whether it's requireAdministrator or asInvoker. Doesn't matter whether it's embedded (VS will embed them for you from 2008 on easily, and there are tools that do just manifest adding) or just a file of XML in the same folder as the exe. Once the app has a manifest, virtualization stops. Of course this may mean the users get all kinds of Access Denied errors that they don't like. Now you see why virtualization was invented.

Should you rely on it? No. For one thing, it may go away in some future version of Windows. And it goes away when you add a manifest, which for many people happened when they migrated to a new version of Visual Studio. What you should do is understand it, including how to find the virtual store, so it doesn't make you quite so crazy.

Now go turn UAC back on,

Kate

Why write a Windows app?

Kate Gregory — Mon, 12 Jul 2010 15:47:25 GMT

There are two services I use not just every day, but many many times a day. One is email and the other is Twitter. Facebook and StackOverflow also get their share of attention, but one thing that sets Twitter apart from Facebook and StackOverflow is the proliferation of clients you can use to access it. You can go to the web page, and do it all in a browser, or you can get any of the many clients available to give you a richer experience. The same is true for email - I can use Outlook or I can use OWA and do it all in a browser.

Recently I found myself facing a full week away from home and the office and with no way to get a VPN although I had great internet access. I could listen to CBC radio and watch Canadian TV but I could not bring my email in Outlook. The first day was ok, but not great. I found myself wanting to email people, and I had to open Outlook to poke around and get their email addresses, then paste them into the OWA new message. It was so different from the usual fast-as-thought process of typing the first letter or two of their names and pressing tab. I also had to delete my own spam, because I don't like server-based spam filters and have been really happy with my client-side spam settings in Outlook. The little preview windows weren't as informative as I wanted, my old appointments weren't showing up, there was no to-do bar, and deleting messages or waiting for the new window when I replied to messages just took too darn long. By day 3 I was about insane. Finally my favourite sysadmin (who I was smart enough to marry almost 30 years ago) got Outlook-over-http working for me and I could go back to normal.

I was utterly astonished at the effect on my mood that not having my client application had on me, and the effect of getting it back. It was very distinct and unmissable. The browser solution just wasn't good enough for me - and OWA is an amazing feat of engineering, with a way richer UI (delete key works, F keys work, etc) than most browser-based solutions. It got me thinking, once my cheerful mood had let me catch up on some outstanding work, about client apps in general. Why do I only use Twitter in a browser? I've tried a whole number of clients but I always end up back in the browser. I think it's because clients have to be well-designed to work well. If they hog resources, jump in your face too much with focus stealing or balloon tips, or insist on being sized a certain way then they don't get a chance to show you their good side. Twitter is pretty young and I don't think we've really had time to winnow the good client features the way we have with email. With that in mind, and believing a good client really will be a better experience, I've decided to try MetroTwit. I've heard really good things about it and I honestly believe that client apps make more sense for these sorts of information feeds. So far, I like it. I get toast for new tweets, a new tweet counter as a taskbar overlay icon, and such a delicate consumption of my CPU and disk activity that I can't tell if it's running or not.

You might also be interested to hear why the developers chose WPF, and what that led to for the team:

over just a couple of months, what we’ve achieved with MetroTwit was simply not possible without WPF considering the few precious midnight hours we put into it on most days. According to the rest of the team (the real developers), apparently I owe much to data-binding which I’ve been told is nothing short of a miracle.

If you have a choice of using a browser or using a client app, which do you choose? Is it always the same or does it vary with the business purpose you use it for? While we don't represent our users exactly, we can still learn from our own personal choices and our emotional reactions to software.

DevX Visual Studio 2010 Showcase

Kate Gregory — Sat, 10 Jul 2010 12:31:40 GMT

I'm not sure when this started, but DevX has a whole area for Visual Studio 2010 articles. They've got handy links to download a trial and a training kit, walkthroughs of creating extensions (a simple blogging one, and adding your own language to the IDE), and lots more. It's a combination of articles, webcasts, and downloads that cover not just Visual Studio but some of the things you can create with it and what's new in related tools. Of course I've seen some of the material before, but that just shows that it's comprehensive. Take a look around!

Another approach to restart and recovery

Kate Gregory — Sat, 03 Jul 2010 00:37:43 GMT

I love demoing restart and recovery. This is the feature that will bring many users to Windows 7 - getting your work back even after the application blows up. Sure, Word saves your document every 20 minutes - but why does it seem I always lose 19 minutes of work? In my simple demo apps, there's a form with one or two controls on it, and one is some text, and when the application blows up I write all the text out, and then on restart I reload it from wherever I wrote it to. It's simple and for most applications it's exactly what you want. But for some applications that approach won't work as well. For example, what if you have an MDI application and the user has 20 or 30 documents open, each with unsaved changes, when the application is terminated? There may not be time to save all those unsaved documents. And then on restart, perhaps the user doesn't want them all restored, or at least not with their real names... it can get complicated.

You are going to need to know your own application and make an intelligent decision about how to handle restart and recovery for your application. But it might help you to know how a certain MDI application near and dear to all our hearts does it ... Visual Studio. Visual Studio does a Word-like autosave every 5 minutes. When the application blows up, it doesn't do anything in particular on the way down. But when it's restarted, it takes a look at the files it has auto recover versions of and asks if you want any of them. You might, you might not, and as the user it's up to you. Zain Naboulsihas a tip-style blog post that explains how it works and how you can control it. Read that for its own sake, since you're probably a Visual Studio user and should be using it as effectively as you can. But also take the opportunity to think about a good design for restart and recovery in your application, which is probably a little more complicated than one text box and one other control.

Camtasia Lights up on Windows 7

Kate Gregory — Wed, 30 Jun 2010 23:22:20 GMT

I'm recording some videos again (I'll announce when the project is live) and I'm doing it, as I really like to these days, in a bootable VHD. I've got the environment set up just the way I like it, without messing with my day-to-day setup, and as an extra bonus I avoid the distractions that Outlook, Instant Messenger, Skype, and the Favorites menu in my browser have to offer. When I went to record the first video I realized I had forgotten to install Camtasia in the VHD so I quickly downloaded a trial from www.techsmith.com. I got to work recording my video, editing it, and so on. Then I rendered the video. This can take a few minutes, but I don't complain because I know it's doing a lot of work. But I got a great surprise ... this latest version uses the taskbar progress bar overlay, so that I can put the rendering into the background and work on something else full screen while it renders. I can still see at a glance how it's doing, but I don't have to keep the little progress window on top. It's a really nice touch.

Then as serendipity would have it I spotted this video on Channel 9 that calls out this and other Windows 7 features in TechSmith products. It's only 9 minutes long, so go and watch it. And if you haven't added Windows 7 features to your client apps yet, why not? It really makes a difference.

Are you using the Code Pack?

Kate Gregory — Sun, 20 Jun 2010 17:26:23 GMT

The Windows API Code Pack is a wonderful library. It wraps many Windows 7 and Vista features so that you can use them from managed code without learning any interop techniques. I've made extensive use of it in demos, presentations, and training materials. I've also blogged about it extensively, primarily in my Client Development category and Windows 7 category.

Folks who've seen the Code Pack in action tell me they are going to use it in their Windows 7 applications immediately, and they're right to do so. Well now I'd like to do a bit of a headcount. If you have a real application (not a demo written to show how Windows 7 features work or how the Code Pack works) please drop me an email (you can see my domain, right? well my address before the @ is just my first name) and tell me who you are, where you work if you made the app for work, what the app does, and whether it's for sale or for internal use. Plus anything else you want to tell me like the Code Pack saved you weeks of work or got you promoted or helped you win the lottery :-). Unless you specify in the email that you're only telling me this, I will be passing it along to some other people, so keep that in mind. I really want to hear what you're using it for, so please let me know!

Tech Ed Wrapup

Kate Gregory — Thu, 10 Jun 2010 14:09:42 GMT

Another terrific Tech Ed has come to a close. I never really got used to the weather in New Orleans, but I loved the food, I loved that we could walk to just about every dinner or party, and I loved the locals I met. I would have liked a little less walking within the convention centre itself - that building is a mile long and I had to go the whole length and back several times each day!

I have a few pictures from inside for you.

This is the "RD couch" in the community area. Good for hanging out while waiting to be on Channel 9. As you can see, non-RDs were hanging out here too.

The table for the Code Pack was giving away copies of the Code Pack on these slightly bizarre USB keys. I meant to keep one for myself but got carried away handing them out at my session (along with cards for a free trial of the Pluralsight On Demand! library). Also the shot-glass-on-a-string-of-beads is pretty brilliant for New Orleans swag. "Give it a shot!" they say.

This is the room for my C++ talk. That's Juval Lowy, who spoke right before me, up on stage. You can see he did a pretty good job of filling the room, which holds 1000. I got somewhat less than that, but was happy with the turnout and the evals for the C++ talk. Both my talks are available online already, by the way, which is astonishingly quick.

I love the "face time" with Microsoft people (including "my" product teams as well as folks in marketing, developer outreach and education, and so on), with my fellow RDs, MVPs, INETA folks, and speakers of all stripes, and with attendees. Booth duty, where you spend long minutes shifting your weight from foot to foot praying someone will come by, is a bit like of box of chocolates. An eager attendee comes forward, meets your eye, smiles ... for every "can you tell me where to find the blinky Windows 7 pen?" there is a good solid question or expression of interest in my actual technology. I got one question on Wednesday from someone who just wanted to know what booth to go to for it to be answered, only to learn it was this booth and that in fact I was probably the only person in building who could have answered it. I sure liked that one!

Next year, Atlanta:

But I may not have to wait a year for another Tech Ed experience. :-)
