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.

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!

I have two sessions
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!

There are thousands of MVPs chosen by Microsoft for their contributions to technical communities. Eric Ligman says there are over 4,000 and I believe him. So of course nobody could choose a single "MVP of the year". There are several dozen this year, chosen from various technical areas and also for reasons that transcend a single technical area. I was delighted and honoured to be among them this year, and even more so to be joined by two of my fellow MVPs. To quote from an email telling us about it:
...the new 2010 C++ MVPs of the
- Kate Gregory,
for her very active role in promoting modern C++ application development, being
among top speakers in some prominent conferences. Kate was also selected by
peers (you guys) as C++ MVP of the Year.
- Marius Bancila – Ovidiu Cucu (shared), for the great job in CodExpert,
their C++ community site (in Romanian language).
- Sheng Jiang,
one of the top answerers in our MSDN Forums.
Is that amazing company or what? We were invited to dinner with a number of MS executives and the other MVPs of theyear during the MVP Summit. Here's a picture of us with Diego, the Visual C++ Community PM:
It was a great evening and it was nice to see C++ well represented.

The pace of C++-relevant video releases on Channel 9 sure feels like it's increased. I watched a few recently (I download them and then watch them in my copious free time) and they happen to fit well with some links I've been carrying around for a while, meaning to share.
Let's start with Herb Sutter talking with Erik Meijer about C++ and whatever else they felt like talking about. The resulting Channel 9 video is a must-watch, and for once I didn't crank it to 1.5x or 2x speed as I usually do with video interviews. When they get into the part about deriving future<T> from T, you might want to pause it and go read Thomas Petchel's post on automatic type deduction. And during the lambdas-and-closures part, let me recommend a quite old post by Eric Lippert and a followup to it that discusses how these things work for C# and how it's a little different in C++.
Then another two-smart-people talk, with Mohsen Agsen and Craig Symonds. It's great to get the high-level perspective of the value of C++ to any software firm. I love that phrase, dark matter, and you may have heard it from me before. After you've watched that one, you need to go immediately to Tony Goodhew's interview where he puts some numbers out that will drop your jaw.
I know, I'm asking for like 2 hours of your life. Even if you don't develop in C++ any more, you should watch these three videos. You really should. Call it industry research if you like. And if you wish you knew a C++ developer, you do

The PDC was a little different last year. It was held on the Microsoft Campus, meaning that only a thousand people could attend, when usually it's 5 times that. But it featured an amazing player that opened the whole conference up to the world. I was one of the 100,000 (yes, 100,000!) who watched online. If you are interested in some of the technical details, there's been a whitepaper released. You can read about it
on the Windows Azure Team Blog. Makes sense, since Azure was a big part of the solution.

Are you doing Scrum? Do you use TFS? Then you should check out Urban Turtle
. Brian Harry
did (yes, that Brian Harry) and he really liked it - his blog post makes a great introduction. It gives you rich visibility onto your project and lets you work with it your own way. You can download a 30 day free trial to see if there is a good fit with the way your team fits and works.
If you like it, let me give you a tip. If you go to DevTeach
in Montreal (which is so worth your while to attend on its own) you will get a 5-user license of Urban Turtle, which means you're effectively going to DevTeach for half price. And you can hear me speak on Windows 7 development, too.

Here's an interesting blog post
. Say you use MFC and are wondering whether anything was added to it in a particular release. What tool would you use for that? How about CppDepend? If you've never used it, seeing how it provides the illustrations for this post should show you the appeal of it. Either way, you're going to learn something.
