The agenda for the Qt World Summit has now been released.

I'll be doing a half-hour version of a talk I've given only once before, "Am I a Good Programmer?" Many people have told me this is something they worry about pretty often.So at the end of November, we can discuss it together.

I've been lucky enough to speak in Berlin at several different conferences and I'm looking forward to being back there again. Would you like to join me? You can even get a discount of 10% if you use the code QtWS23_Kate -- register here.

I spent much of the spring working on this course, and am delighted to see it live!

Visual Studio 2017: Essentials to the Power User is 7 hours of good stuff you need if you're a Visual Studio user. My emphasis is on keeping you happy and productive by getting the tool to help you and showing you neat features you probably didn't know about. If you open that link in a new tab, you can play the course overview (a 2 minute "trailer") and look at the table of contents. I've done versions of this course for older Visual Studios and I get comments like "It's as though I have a whole new IDE" and "I've been using Visual Studio for years and you showed me things I didn't know, and I'm glad I do now."

I think debugging in general is not taught enough, so I'm happy to have 2 whole modules on it here - not on philosophy of debugging or how to narrow down a bug, but just on how to operate the machinery of Visual Studio's debugger. There's lots of it. Plus, if you have Ultimate, there's another half a module on "Historical Debugging", IntelliTrace. I also spend quite a lot of time on how to find your way around a large codebase with the various searching, finding, navigating and exploring capabilities that have evolved over time.

Here's a quick topic summary:

I really enjoyed writing this course and hope you enjoy watching it. If you need a free trial, look over to the right on this page for the grey rectangle that says Author and click for a 10 day trial.

Kate

In yesterday's session, I showed a Windows 8 store app that loads an image and then draws an animated ripple over it.

If you would like to get the code, and more importantly the documentation that explains the code, it's on Codeplex. Mixing and matching a little DirectX into your Windows 8 C++/CX app is remarkably easy, so why not take a quick look?

Kate

Were you at my session today?

If so, you might want this code. If not, I am not sure the code will help you much :-)

Kate

I write a lot in Microsoft Word. A Lot. And much of it is for my own purposes - say a list of things I need to keep track of, or a summary of my meeting notes. I use the Ctrl-F command to bring up the navigation pane, and I click the leftmost tab on that pane to show an outline view instead of the Find dialog:

Right away you can see something useful going on here. The Four section is highlighted yellowy-orange because that's where the cursor is. If I add sub-sections, the outline gets even more useful:

I guess you knew that you could click a heading in that navigation view and the cursor would scroll there. That's mostly what I use it for. But there are some documents that I have in a two column view, so that I can fit more short lines onto a page. (It's a perfect approach for lists that are slightly more complicated than a to-do list, for example.) This two column layout makes it really hard to select one section with the mouse and move it around, especially if it's a section that crosses the column break.

Or imagine a really long document where each of these sections is about 20 pages long, and you want to move "Possible Risks" before "Motivations for the Schedule". You could click at one place, page down a lot, and shift click, but it's awkward. I just learned I can drag and drop sections in the navigation pane! That's right, click on the Two in the nav pane, drag it a little and watch for the black horizontal line:

When you let go, the section has moved (and the whole section is selected):

This saves me so much time and frustration, I just had to share it. Maybe your client apps can offer some truly delightful drag and drop too?

Kate

Over the last few weeks, I've been accumulating links to appearances of mine, and it seems like a good idea to share these.

• OReilly webcast: This is a reasonably horrible recording (sound quality and video size) of a webcast I did back in August. It shows why C++ AMP is so cool and why you might care about it. I recorded it to promote the book but I'm not very happy with how it turned out. You'll probably do better with the recording of my Tech Ed talk.
• Pluralsight interview: This is specifically about my Using Visual Studio 2012 course. You can download the audio or read the transcript as you prefer.  My favourite quote from the conversation:

It’s not just like, oh, I saved five seconds. I can go home five seconds earlier today. It’s that you’re less likely to forget what you were doing because you don’t have to put so much time into the mechanics and you just stay in flow. And to me, that’s a ramping up of two or three times the amount of code I can produce when I use everything the tool has to offer.

• Dot Net Rocks panel at DevIntersection: Here Scott Allen, Michele Leroux Bustamante, Woody Pewitt, and I discuss whatever we feel like, with occasional leading questions from Carl and Richard, and some Canadian whisky too.

Even though I haven't been blogging much, I have been doing a lot, and I hope these links will help you to discover some of it.

Kate

While I was in Nashville as part of the Dot Net Rocks Roadtrip, we recorded an episode of The Tablet Show. The recording is online now and I'll have to give it a listen myself to remember what we talked about - Hilo, for sure, and C++ AMP, and just generally why C++ can be a great choice for tablet development.

Kate

Don McCrady, who with Jim Radigan did an inspiring talk on performance at Build this year, has blogged about a proof-of-concept project that adds C++ AMP to CLANG and LLVM using OpenCL underneath instead of using DirectX the way Visual Studio does. This is super cool! As Don says:

When Microsoft announced C++ AMP back in June 2011, we told you that we would release the C++ AMP specification under the Microsoft Community Promise – essentially opening up the specification to allow any C++ compiler implementer to add C++ AMP to their compiler. Shevlin Park serves as an example of the platform portability potential intended by the Community Promise.

Do read Don's post and follow the links to learn more about Shevlin Park. The praise for C++ AMP as a programming model, and the likelihood that multiple compilers will support it, should make you feel all warm and fuzzy about learning it. You might even want to use my book to do so :-)

Kate

Day 4 was the first time I started to experience what some others had been complaining about with not being able to get into the room for a popular talk. I guess I'll just have to watch the recording.

I remembered to take some pictures of the signage that directed us around to help cope with being in two different buildings plus the tents:

One of the stickers for the badge this year was to attend an 8:30 session. I achieved that by going to Alive with activity: Tiles, notifications, and background tasks which, to be honest, I chose as much to see what Kraig Brockschmidt is doing lately as to learn about tiles and toast. But I'm glad I went, because it was a very good talk.

I've come to Redmond so many times, but I never particularly noticed the colours changing. This week they've been spectacular. I had some meetings in other buildings so I was able to get out of the giant lines at least long enough to take pictures of the giant lines :-)

I really enjoyed my evening in Nashville. It was fun answering the question: C++ - Why on earth? I think I even convinced a few of you.

Of course the biggest Nashville attraction for me is my friend Billy Hollis:

Look what a luxurious meeting room they have! Couches and tables and general comfort. And yes, I got to see the inside of the RV:

If I got you interested in C++, you might like some links:

• My C++ AMP book
• My courses at Pluralsight that include some nice C++ ones
  

Thanks for the visit, and I hope to be back!

Microsoft and Stack Overflow are joining forces on a fun Windows 8 development contest. And since one of the strengths of StackOverlflow is how the community reviews all the content, it only makes sense that there's a serious review component to this contest! And it's not US-only (for once!) so as long as you're over 18 and don't live in Cuba, Iran, North Korea, Sudan or Syria you're good to go. Well, you need a StackOverflow account, but you needed one of those anyway, right?

Top prize is $5,000 and there are shiny achievements and everything - so get going!

Event Agenda

One the Esplanade
Pickering, ON L1V 6K7

Here's an amazing grand finale to the Dot Net Rocks Roadtrip this year -a full on developer conference in Las Vegas, Dec 9th - 12th.

I love this answer to "What is DevIntersection?"

This three-day conference marks the final stop on the USA leg of the .NET Rocks! Visual Studio 2012 Launch Road Trip! DevIntersection is a developer conference PLUS the recording venue for the last stop of the three-month road trip hosted by Richard Campbell and Carl Franklin. We're bringing together some of the best speakers (and our personal friends) for a conference that is relaxed and educational, plus forward looking as you and your company start to figure out what to do with Windows 8 and Visual Studio for the next few years. Our attendees tend to be .NET software developers plus other members of their teams. DevIntersection is an educational onsite conference for anyone who is attached to a .NET development programming project who is looking to use Visual Studio to develop apps for desktop, web and mobile platfoms.

I have two breakout sessions - one on C++ AMP and one on developing for the Windows Store in C++. No .NET in either one of them; this is a conference for expanding your horizons, after all.

For $1595 you get three full days of sessions. And if you register in October (hurry!) you will also get a new tablet. Build sold out in hours, so this is your chance to get access to deep and current information for developers across the Microsoft ecosystem. See you there!

Kate

Hilo is a reference project written in C++/CX for Windows 8 by the Patterns and Practices team. I was delighted to be part of this project and think it turned out very well. I use the Hilo codebase to remind myself how to do certain things when writing a Windows Store app in C++ (something I'm in the middle of doing for another project.) The accompanying document is rich in best practices for Windows 8 development, async work, modern C++, unit testing, and more. Now the latest version has been released, updated for Windows 8 RTM.

Hilo itself is a photo viewer. Before you roll your eyes, bear with me. I actually think it's better than the one that ships with Windows 8. It shows you some of your pictures as a sort of overview:

Click on one to interact with it. You can right-click to bring up both the app bar at the bottom and a nice strip-navigation control at the top:

If you want to see something cool, use Cartoon Effect. This leverages C++ AMP to cartoonize the picture. I've shopped this image a little to reduce the width (pulled the appbar in from the edges) but the cartoon work was done by Hilo - and super quickly.

If you have any thoughts of writing Windows Store apps, and C++ is a possibility for you, get over to Codeplex, download the Hilo code and the .chm file, and get reading!

Kate

I love writing courses for Pluralsight. I have quite a few and am working on more right now. They like to interview their authors about each course. Here's one about my latest for them. If you’ve done the whole course you won’t learn anything new from the interview, but if you’re curious about writing what we’re now calling Windows Store applications for Windows 8 using C++ and Visual Studio, perhaps this interview will help you decide whether it’s something you want to learn. There’s a transcript as well as an audio link.

Kate

We now have a Windows Phone application in the marketplace. We wrote it for ourselves, to learn the framework and to give us a way to track how we spend our time. The minute we started designing it, we discovered everyone in the company wanted a different way to track. People who do pretty much the same thing all the time (coding, for example) wanted to track project-by-project. People who work on only one project at a time wanted to differentiate between types of work, like meetings or email or writing documents. We decided to make it as simple and flexible as we could. I was inspired by a story of a time tracking technique involving physical objects. You get 5-10 paper cups and write things on the cups like Email, Meetings, and so on. Then you get 32 poker chips, all the same colour. As each 15-minute piece of time goes by, you toss a chip into the cup. It is supposed to help you understand that you very literally “spend” your time. And at the end of the day you can look in the cups and see where your day went.

If you’d like to track your time like this – hit the + button to toss a “15 minute” square into a particular “bucket” or just hit the falling drops button to accumulate time in one bucket until you change tasks – please try our app and let me know how it works for you.

Kate

I've been putting my schedule together for the talks I want to attend at Tech Ed North America and Tech Ed Europe this year. While I wasn't looking, a bunch more C++ content was added.

In Orlando:

• PRC08, my all day Sunday precon: C++ in Visual Studio 11: Modern, Readable, Safe, Fast
• DEV316, Wednesday at 8:30 am: Application Lifecycle Management Tools for C++ in Visual Studio 11 by Rong Lu
  
• DEV334, Wednesday at 5:00 pm: C++ Accelerated Massive Parallelism in Visual C++ 11 by me
• DEV322, Thursday at 4:30 pm: Building Windows 8 Metro style Apps with Visual C++ 11 by Raman Sharma 

Plus some language agnostic sessions that chose to put C++ in their session descriptions, which is a new thing these days.

Now as it happens, Tech Ed North America is sold out, so if you're not registered yet, you have three choices: join the waiting list, watch these sessions online, or get your boss to agree to a slightly larger T&E budget and head to Tech Ed Europe in Amsterdam just two weeks later. There we will have:

• PRC08, my all day Monday precon: C++ in Visual Studio 11: Modern, Readable, Safe, Fast
• DEV316, Tuesday at 4:30 pm: Application Lifecycle Management Tools for C++ in Visual Studio 11 by Rong Lu
• DEV368, Wednesday at 2:45 pm: Visual C++ and the Native Renaissance by Steve Teixeira
• DEV322, Thursday at 8:30 am: Building Windows 8 Metro style Apps with Visual C++ 11 by Rong Lu
• DEV367, Thursday at 4:30: Building Windows 8 Metro Style Apps With C++ by Steve Teixeira
  
• DEV334, Friday at 1:00 pm: C++ Accelerated Massive Parallelism in Visual C++ 11 by me
  

(Europe doesn't have direct links to the sessions, but they do allow links to the search for C++.) I'll have to miss Steve's talk because Rong and I are going to Belgium, so that one I'll be watching online. 

One way or another, please attend or watch these sessions. There's a lot of new stuff happening!

Kate

• Modern C++ with the Standard Library
  
• Application Lifecycle Management for Visual C++ 11
• Leveraging Lambdas for the PPL and C++ AMP
• Best practices for C++ developers today

This is not a free session, but the price is even lower than the Tech Ed precons since I don't have travel expenses to get down there and see you all. If you live in Australia, please register and take advantage of this chance to come and learn what's been going on with C++ while you weren't looking! And if you don't, I'd appreciate it if you could spread the word to those who do.

Kate

• I updated my C++ Windows 8 Development course for the Consumer Preview of Windows 8. There were a few breaking changes, so if you're working on a Windows 8 app, take a look through it.
• I'm part of a group working on a Windows 8 app in C++ and XAML called Hilo, inspired by the Windows 7 Hilo application. You can read more about it on Scott Densmore's blog, the Parallel Programming in Native Code blog, and the Codeplex site. There's another related blog entry, too.
  
• There are Windows 8 development camps going on all over the place, but most of them are in managed code. There's a native C++ one happening in Redmond on May 18th, and it's going to be live streamed.
• Don't forget my Advanced Topics in C++ course. I did an interview about it recently.
• Then there's C++ AMP - the topic of the book I'm spending all my time writing. They're hiring. This is a great opportunity for the right developer.
• Oh, and James McNellis spent the last however-many-months answering the question "hey, if native WinRT has all this metadata about types, could you leverage that to implement reflection for native code?" Which for some people was a rhetorical question or interesting thing to muse about, but he went and did it.  Incredibly cool.

It's hard to keep up with it all! Especially when I'm on a book deadline :-)

Kate

My C++ precon, an all-day session about modern C++, has had a slight title change and is now called PRC08, C++ in Visual Studio 11: Modern, Readable, Safe, Fast. The content is still the same. My high level outline is:

• Modern C++ with the Standard Library (demo of strings, shared pointers)
• Application Lifecycle Management for Visual C++ 11
• Leveraging Lambdas for the PPL and C++ AMP
  
• Best practices for C++ developers today

I've been working on another C++ course for Pluralsight to complement the C++ WinRT/Windows 8/Metro course I did as well as the two-part C++ Fundamentals course (part 1, part 2). It's finished and live!

The topics I cover are:

• Avoid Manual Memory Management
• Use Lambdas
• Use Standard Containers
• Use Standard Algorithms
• Embrace Move Semantics
• Follow Style Rules
• Consider the PImpl Idiom
• Stop Writing C With Classes

I had a real blast writing this - while I was editing it I could hear my own enjoyment of parts of it. I hope you enjoy it too. A Pluralsight subscription is such a bargain - buy one for the topics you simply MUST learn for work, then use it on your own time to learn all those other things that you think you might benefit from. (I recommend Annual Plus - $500 gets you the sample code and offline viewing, all you can learn for a year.) Whether C++ is "must learn for work" or "I hear it's different know, wonder if it could help me" for you, I hope you find it helpful. Please let me know!

Kate

The minute this was announced, I knew I had to go.

Two days of "C++ today and tomorrow" with the bright lights of C++ today? Just try and keep me away! I'm so glad I was there - it was AMAZING and FANTASTIC and just generally wonderful. For me, personally, seeing so many old friends was a big part of it. The C++ team, other C++ MVPs, people I went to university with, and so on. It was also wonderful to see so many young people - including speakers, but also attendees, who were clearly in their 20s (and a few who were obviously in their teens.) After Chandler's talk I told someone "we can retire now: the future of C++ is in good hands." The speakers were not "the usual suspects" at a Microsoft event either. At a panel at the end of the second day, someone asked about C++ and the cloud and one of the answers was to indicate three speakers sitting next to each other: "Microsoft guy, Facebook guy, Google guy. Where isn't C++ in the cloud?" While that was a great cloud answer, I think it also highlights how inclusive this was - it was a C++ conference held at Microsoft, not a Microsoft conference.

Some fun quotes I happened to write down:

• “if it’s that ugly, it must be good” - Bjarne, on why some newbies imitate horrible code written long ago by their heroes
• “write C-style code, expect C-style errors” - Bjarne again
• “we know where bugs hide” – Bjarne (they hide in large tracts of complicated code)
• "dot dot dot is where the fun begins" - Andrei
• "real code is not supposed to fit on slides" - Andrei
• "this is legal" - Andrei (we needed to be reassured since it rarely looked legal)
  
• "if you're using new or delete, you're doing it wrong" - Herb (it's true!)
  

And Chandler's talk was very much a 2012 talk, with lolcat-like interjections and Simpsons references and even a how-agile-is-this update with a picture of Oscar Wilde in reference to Andrei's earlier off-the-cuff description of some template error messages (aka template barf) as being "a small novel by Oscar Wilde." The humour level was very high, much of it self-deprecating - no-one, not even the coiners of the terms, thinks RAII or SFINAE are great names, but what the heck, they're the names we use.

Even the little things here were so well done. Herb opened the conference by dedicating it to Dennis Ritchie, which I found extraordinarily touching and appropriate. He opened day 2 by celebrating the 20 year anniversary of Microsoft C7 which was C++ 1 for them, with Visual C++ appearing in the next release. There on the podium was the two foot long, 44 pound box, with multicoloured plusses all over it, in which it shipped.

And what was inside? A lot of books, and a lot of 3.5" floppies (I took this picture earlier, before the box headed to campus):

There are 5 or 6 floppies in each bag and apparently each bag had a part number of its own.

This conference was far more than a trip down memory lane, of course. It was a two-day Valentine from Microsoft to the C++ community, a demonstration of the "new growth" in modern C++ and the power and capability that is there for those who are prepared to start using the new features, and a chance for all of us to accelerate the learning we have to do. I so hope you were able to be there, or to catch the energy by watching it live and following tweets from those of us who had to share the bon mots and the fun. But if not, the on-demand videos are almost all there now. Here are the links:

Bjarne Stroustrup : C++11 Style

Hans Boehm : Threads and Shared Variables in C++11

Stephan T. Lavavej: STL11 – Magic && Secrets

Andrei Alexandrescu : Variadic Templates are Funadic

Panel: The Importance of Being Native (Bjarne, Andrei, Herb, Hans)  

Herb Sutter : C++11, VC++11 and Beyond

Chandler Carruth : Clang - Defending C++ from Murphy's Million Monkeys

Andrei Alexandrescu: Static If I Had a Hammer

Bjarne Stroustrup and Andrew Sutton: A Concept Design for C++

Panel: Ask Us Anything! (all speakers)

Fair warning: both of Andrei's talks, and the Concepts talk, are hard. This is cool new stuff that we are all learning about. There is no shame in pausing, rewinding, and giving something a second listen. Look, Chandler was running through pitfalls and problems that Clang catches, and showed some code with a problem I couldn't spot. A few minutes later in the Q&A, Bjarne asked him to clarify just what the problem was. Made me feel better!

Chances are you won't be able to watch any of these on fast forward, or skip any of them. So I'm asking you to invest 12 hours of your life to watch all of them. Do it! You won't regret it!

Kate

PS: They gave us shirts (it's all about the shirts for developers) with real code on the back and this on the front:

Oh my goodness. What a week that was!

Here's how I thought I would do my first summary. Links to videos, discussions of sessions I either went to or tried to go to (more on that in a moment) along with my tweets from the ground, as it were.

My first real tweet Tuesday morning (8:37 California time) was announcing that my PluralSight C++ Fundamentals course had gone live. Then the keynote started. Here are my tweets and retweets along with the time into the keynote I said them:

• 6 minutes: #bldwin totally dominating my stream SS doing a good intro to lean back computing

• 127 minutes: RT @jonbrasted It is a great day to be a Windows developer. #bldwin #trbbuild
  
  

• 8 traits of great Metro style apps - a truly excellent session by a presenter who cares deeply about the topic. I tweeted a lot less during this one because it required more active listening.
• Platform for Metro style apps - another very good session during which I just retweeted some other people's "Hey, this stuff is C++" reactions and a link to the session planner app for the phone, which I used heavily.

• @coridrew #bldWin is really, really, really making me want to //BUILD/ Windows apps #BestConferenceNameEver #WhoKnew

• @mcakins Wow, the silence from Apple's camp is deafening! Windows rocks once more! Its 1995 all over again! #bldwin

One more session: Tools for building Metro style apps - I was getting tired at this point. It was a lot to take in. People were lined up the length of the convention centre for tablets. I knew there were enough for all of us, so I went back to my room to edit my pointers module for the PluralSight course so it could "tack on" to the end of the published course. While videos rendered, I had a little back and forth on Twitter with people who had noticed how much fun I was having, and others who were playing with their tablets already. I slipped out to pickup the tablet about 7:30 but didn't open it till the module was done. Then:

• 10:48 pm: got major piece of work done ... yielding to temptation ... tablet here i come #bldwin
• 10:57 pm: How's that for fast setup? Everything's installed.... Trying visual studio next
• 11:11 pm: Just wrote a Win8 C++ app on the tablet with touch keyboard. Built and ran first time. #winning

• 17 minutes: RT @seesharp 3D graphics debugging at the pixel level in DirectX. Unreal. #bldwin
• 33 minutes: RT @bgervin killer strategy for MS to help developers make HTML apps for iOS and Android #bldwin
  
• 34 minutes: RT @tpdorsey RT @EisenbergEffect […] in C++, you can write your own WinRT library, which when built, can be used by C++, C#, VB and JS.
• 34 minutes: RT @jmorrill This new COM and C++ version is not _anything_ like what you think it is. From what I can tell so far...effing amazing!!!!
  
• 49 minutes: Loved it RT @MichaelDesmond Zander shows off the new image editor in VS11 as he works on a C++ DirectX game.
• 54 minutes: RT @shycohen Moving a VHD while the machine is running is cool. Moving a live VHD is even cooler! :) Will enable amazing things in the future. #bldwin
• 82 minutes: most tattoos ever in an MS keynote
• 95 minutes: RT @seesharp WOAH. Did not expect Steve Ballmer today. Everyone was starting to leave already. Woah! #bldwin
• 97 minutes: RT @carafone 500,000 downloads of #win8 already! #bldwin
• 98 minutes: RT @LACanuck And #Win8 was downloaded 500K times in 12 hrs RT @mashable: RIM Has Sold Just 490,000 PlayBooks - on.mash.to/nEu0dU #bldwin
• 102 minutes: That's what these keynotes were missing! Turns out it's a great time to be a developer. I was worrying, no-one had told me yet #bldwin
• 105 minutes: I've been paid to program since 1979. Keynotes tell me at least once a year it's a great time to be a developer. And they're right. #bldwin

Instead of declaring a base interface class with virtual functions then deriving each platform with a different implementation, we declare a class with one template parameter — a platform ID — then specialize it to provide a different implementation for each platform.  The template class is then typedef‘d to expose the specialization for the platform ID being compiled to the application, allowing the implementation to be used without any virtual functions and also allow for inlining of functions as well.

The Mastermind code sample demonstrates how to create a simple Silverlight storyboard in Expression Blend 3, and then provide the code for the state transitions in Microsoft Visual Studio 2008. You can also see how to create brushes programmatically and how to add a title bar to a Silverlight-based app.

• "You can of course still use MFC but I do not recommend it as modern C++ can do a better job of supporting the Windows developer."
• "You should never again use auto_ptr for anything."

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.

Today saw the release of the first episode (naturally, Episode 0) of GoingNative on Channel 9. As the introduction says:

GoingNative is a new, monthly show on C9 dedicated to native development and native developers, with an emphasis on modern C++.

You know there's been a lot of talk about the C++ Renaissance. I'm happy to see that phrase get picked up, and I've got another one for you: Modern C++. Or as some folks like to say "not your father's C++". If you think C++ means manual memory management, strings as arrays of characters and a strange cast of global functions, and longing for a library or framework that might rival what .NET has to offer, then you haven't been keeping up with C++. The good news is that it won't take you long to catch up - shared_ptr and unique_ptr, the Standard Library, lambdas and other Modern C++ goodies are easy for both managed developers and longtime native developers to learn.

In Episode 0, Charles Torre (longtime C++ friend) and Diego Dagum (C++ Community lead, blogger, and Tweeter) lay some groundwork and, of course, show code. It's always about the code, right? Then, they ask you to get involved. Whether you're someone who wants to learn about C++, or someone who wants to make sure something about C++ gets taught to others, speak up! And yes, that includes topics on non-Microsoft platforms. Email C9GoingNative - they're using hotmail - or on twitter, follow or talk to @C9GoingNative. (There's a Facebook group, too - whatever way you like to interact is welcome.)

But wait, did that sound like a whole episode? Nope, they grab the camera and head over to see Ale Contenti - one of my favourite team members and one I've done interviews and sessions with before. His talk gets technical fast, which is one of the things I like about him! I too have a soft spot for 6502 assembler :-) and find template meta-programming a bit of a write-only technique. I, too, like "the power the language gives you to make the language bigger with libraries" and think that's part of the appeal of C++ for me. Well, that and the power and performance and control, of course. Are there downsides? Well, there's what Joni Mitchell called "the crazy you get from too much choice" - C++ gives you many ways to do everything, according to your circumstances, and having to decide how to do it, or having to connect two components that made different choices about something as simple as how to represent a string, can be frustating. As well, it's great to be in control, but that does mean that nobody is looking after you. If you're inexperienced (and sometimes, even when you're not) you can make dangerous choices and, as we like to say, shoot your foot off. Security holes and vulnerabilities are important and C++ will let you write bad code, so you need to be aware of best practices. Both Ale and Diego address these points, and you can expect to see more of that in time to come - especially if you ask for it!

Looking forward to next month's show already,

Mind Control Your Computer In C#

No really. This isn’t some clever session title. I’m really talking about controlling your computer with your mind. I’m not making this stuff up. This is real. Today. You put on a headset, you use a C# SDK and you control your computer with your thoughts. Yes, you are reading this right – you mind control your computer. It is a reality and it is possible today. Once you’ve gotten over your disbelief consider the applications. Applications for the physically impaired alone are a whole revolution. Not to mention the possibilities for gaming. Want to be shocked and amazed ? Come and see this session.

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

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.

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!

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.

Kate

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!

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!

Like a lot of folks, I have a Windows Phone and I enjoy it a lot. I've filled it up with (free) games and they pass the time quickly when I have to wait in line or otherwise have an empty minute or two. C++ MVP Marius Bancila had the same experience, but unlike me he responded by writing a version of the game in MFC so he could play it on his own PC as well as on a phone.

You can get the source from his blog post, and another post and its comments (mostly in Romanian - Bing Translate is your friend there) have a nice discussion of performance issues. After all, whenever two or more C++ programmers gather together, someone is going to have an opinion about performance. Take a look for yourself!

Recently the East of Toronto .NET User Group had a Windows Phone 7 presentation (by Atley Hunter) that was very well done, and well attended. (He's blogged about it and included some helpful links, so you should be sure to read his post too.) You would never have known it was his first presentation - he was calm and confident and knew what he was talking about.

At the meeting I met Ashish Kaila, who is working on a toolkit for WPF developers and a Windows Phone 7 library. He showed me the docking panes and some other fun functionality.

To me this is a huge benefit of user group meetings: in addition to the presentations, usually as good as any you would see at a paying conference, you also can meet fellow attendees. I hadn't heard of these tools before, and they could save you a lot of time and effort. The next best thing to coming to meetings, I suppose, is reading blog posts about meetings. Here's where you can learn more about Ashish and his products:

• Building a Docking Window Management Solution in WPF
• Create Custom Windows in WPF with Ease
• MixModes Synergy - The Ultimate Plaform Toolkit for WPF, WP7 and Silverlight

If you're not going to your local user group meetings, why on earth not? We don't bite, honestly, and you have so much to learn and gain from being there. See you next time!
