Some people don't like the different kinds of punctuation in C++. I do. I like having :: and . and -> instead of always dots. And in C++/CLI I really like having ^ instead of overloading * to mean either pointer-to-native-heap or pointer-to-managed-heap. But you know what some people say about C++, don't you? That it looks like comic book characters swearing? Well here's what I say to that:

Julie blogged this a while back, and mentioned to me recently that the firm needs someone again. If you know C++ and MFC, know what the .NET Framework can do, and can write English sentences as well as code, then you can live in a lovely place and do some cool work. Check into it (follow the link from Julie's blog) and mention me as well as her when you apply.

Recently, Jim Allchin (Co-President, Platforms & Services, Microsoft Corporation) posted an open letter to developers. In it he points out that it's one thing to beta test a new operating system (as I and thousands of my closest friends have been doing with Vista) and it's another thing to adapt your applications for a new operating system. For me, there are two important parts to that:
- What do I have to do to my application to keep it from failing in the new environment?
- What can I do now to my application so that it will take full advantage of the new environment?
Some Vista-specific examples of this might be "how can I be sure my application will not trigger a bunch of UAC dialogs?" and "will my app have glass?" or "can I get those cool Task Based Dialogs with the blue arrows and stuff?" These are the sorts of things I'll be tackling in some of my upcoming talks. I hope my Vista category will also be useful. My point is, don't wait until Vista ships, then wait to see if any of your clients or customers feel like using it, and then wonder if you have a Vista-ready app. Find out now.
Or as Jim says, "... the opportunity will be tremendous. If you want to ride the wave we're creating with Windows Vista, the best way is to have your application ready by the time we ship! And that is very soon. "

In October, Kathleen Dollard is coming to the East of Toronto UG! On October 19th, she'll be talking about Generics. Specifically:
Generics open up new opportunities to increase the robustness of your code, improve its performance, and significantly reduce the total amount of code you write. After a brief introduction to generic syntax, this talk dives into using generics to improve the quality of your code. You'll see how easy it is to shift your current collections to generic collections and learn about new features such as robust sorts, finds, and filters across collections. You'll learn how to write your own generic methods and classes. Finally you'll see how to leverage the spectrum of generic possibilities in a business object hierarchy that reduces the total lines of code by about 50%. You'll walk out of this talk understanding how to use generics to improve your own applications.
This meeting is at the YWCA Durham, so when you register, check the map and make sure you know where you're headed. If you haven't heard Kathleen speak before, you need to be there. Here's a little more about her:
Kathleen Dollard is a consultant, author, trainer, and speaker. She’s been a Microsoft MVP since 1998, wrote “Code Generation in Microsoft .NET” (Apress) and is a regular contributor to Visual Studio Magazine. She speaks at industry conferences such as VSLive, DevConnections, and Microsoft DevDays as well as local user groups. She’s the founder and principal of GenDotNet. Her passion is helping programmers be smarter in how they develop by learning to use Visual Studio, XML related technologies, .NET languages, code generation, unit testing, and other tools to their full capacity. She’s currently working on full life cycle improvements, such as better debugging and capturing business intent in metadata and test definitions. When not working, she enjoys woodworking, snowshoeing, and kayaking depending on the outdoor temperature.
I'll be a little crazed that week getting ready to head to Africa, but I'll be there.

Jean-Luc David, newly minted Developer Advisor, returns to the East of Toronto .NET Users Group this month to talk about Atlas, or "Atlas" as the Microsoft guys used to call it, the quotes reminding us all that it's a code name, not a real true blessed-by-marketing-and-the-lawyers name. And now, it's going to be called, sort of, AJAX. Let me quote ScottGu here:
The server-side “Atlas” functionality that nicely integrates with ASP.NET will be called the ASP.NET 2.0 AJAX Extensions. As part of this change the tag prefix for the “Atlas” controls will change from <atlas:>to <asp:>. These controls will also be built-in to ASP.NET vNext.
The “Atlas” Control Toolkit today is a set of free, shared source controls and components that help you get the most value from the ASP.NET AJAX Extensions. Going forward, the name of the project will change to be the ASP.NET AJAX Control Toolkit.
Well, whatever it's called (I seem to say that a lot) you can learn more about it at this month's user group meeting. September 26th, 6pm for pizza, 7pm for the presentation, Whitby Public Library. Please register!

Larry blogs that improving your app's performance means concurrent programming. Not just OpenMP, which is very cool, as he points out elsewhere, but all the hard stuff: "disk contention, memory locks, cache corruption, etc". Still, here's a tempting paragraph from that DevX article:
It's perhaps surprising that C++, with its reputation for difficulty, actually provides one of the easiest ways to exploit multi-core and multiprocessor systems. OpenMP, a multiplatform API for C++ and Fortran, uses compiler instructions to automatically generate all of the support code needed to parallelize code sections. In the simplest case, which is what we're going to focus on for this article, simply wrapping a processor-intensive loop in a #pragma block can lead to about a 70 percent performance increase on a dual-core or dual-processor system and enjoy a similar "free lunch" on the quad-core systems that you build in the future.
That's right. Concurrency is vital, and C++ takes care of one kind of concurrency astonishingly easily. It's true. Later in the article he plops a #pragma just before each of two loops, and his app runs 70% faster. How's that for fun? Go on, read the article, try it yourself.

Tomas Restrepo, a C++ MVP, has started a C++/CLI FAQ at http://www.winterdom.com/cppclifaq/. It's a start, and since some questions are starting to be frequently asked, it's a good idea for folks to read through this.
BTW, if you're looking for a more general Visual C++ FAQ, try the multi-MVP effort at http://vcfaq.mvps.org/.
Both recommended. Good work Tomas!

According to a summer IT Business article, there is still a battle or maybe there isn't. The headline reads "Java vs .Net: The tug of war continues" while the first sentence of the article is "The religious war between Java and .Net seems to be over." You might be able to guess how I feel from these quotes:
- "It's .Net all the way," she said. "I hardly ever get e-mails (from students) asking [whether] they should learn C# or Java any more."
- "I feel more productive on the .Net side," said Gregory, who also programs in Java. "When I made the jump, it was about the tools in Visual Studio, and the libraries."
- "I think that every time we have a new batch of libraries and every time the products are improved, people will change (platforms)," said Gregory. "Others say they will stay. And they're both right. Maybe younger developers get caught up in a religious war, but older developers say, 'You go ahead and use whatever you like. I'll be over here getting some work done.'"
That's why I'm a VB.NET and C++ developer after all -- to get some work done.
