Here's another C++ video on Channel 9. And this one is about strategy and vision:

How will VC++ evolve? How has the advent of managed code affected the evolutionary trajectory of VC++? What's the VC++ team up to these days, anyway? How much time are they spending innovating C++, the native language?

Tune in and learn first hand from two people who know the answers to the above questions (and much more); Steve Teixeira, Group Program Manager, and Bill Dunlap, Program Manager.

If you want to know where Visual C++ is heading, then you definitely want to watch this interview. If you are a C++ developer, the message should be very loud and clear: Microsoft has not forgotten about you!

These guys know you don't want to throw your old code out and it isn't broken. You want to keep working with it. You want to extend it to pick up new shiny good stuff, but you don't want "step 1: port the whole thing to C#." They also know you love the language and you want Microsoft to love it and love you. And they realize that C++ doesn't need to be all things to all people, because most folks who have mastered C++ can pick up the C# or VB they need when necessary. So if you accept those two premises - that native code is super important, and that not every single UI wizard needs to support C++ - where do you think that leads? Watch and find out.

Aaron Stebner has a blog post and an update on installing the C++ redistributables (msvcr80.dll, atl80.dll and the rest.) You can choose

  • the user doesn't need to do anything, but there's a progress dialog and it has a cancel button
  • the user doens't need to do anything, there's a cancel dialog, but no cancel button
  • there's no ui at all and nobody knows what's happening

Turns out the command line you use varies a tiny bit for redistributable packages you installed with Visual Studio or those you get from the web, so read both posts.

You know what they say: if I knew, I couldn't tell you. But Mary Jo Foley doesn't mind a little speculation, and Scott Guthrie seems pretty clear on timelines in the blog and presentation she quotes. So it's either "late 2007 or early 2008" or "later this year". But don't say I said so :-)

Visual Studio 2005 SP1 included new versions of some C++ libraries. Your application's manifest specifies what versions of the DLLs it wants -- so if you build with SP1, the application is going to look for SP1 versions at runtime. That has consequences for your deployment strategy, since non developers are unlike to have SP1 versions of those DLLs yet.

Nikola Dudar has gathered some questions and answers on this topic. I'll give you the questions, read his blog for the answers:

  • It looks like with VS2005 SP1 if a new version of VC++ libraries is installed, all apps start using it. Is this new policy for VS2005 SP1?
  • When my application is rebuilt with VS2005 SP1 it runs only when SP1 versions of VC++ are installed. Why does not it run when RTM versions of libraries are installed? Is this new policy for VS2005 SP1?
  • This behavior of VC++ libraries in VS2005 SP1 is it only specific to SP or is it going to be same in future releases of SP and hotfixes?
  • Wasn't the whole point of manifests to allow applications to specify the versions of VC++ libraries they want to load?
  • My application is using a DLL that is built with VS RTM. The application links against import library of that DLL and call exports of that DLL at runtime. Is this going to work with VS2005 SP1 and other SPs?
  • My final product is a set of DLLs. If I release a version of my DLLs built with VS2005 SP1, can my users who use VS2005 RTM to use these libraries?
  • My application is linking to static library party is built with VS RTM. Is this going to work with VS2005 SP1 and other SPs?
  • I see VS2005 SP1 has installed SP1 version of VCRedist*.EXE. Should I send it to my customers and ask them to install it?
  • I am using MSMs to redistribute RTM versions of VC++ libraries. Should I sent SP1 version of VCRedist.EXE to my customers and ask them to install it?

If these questions matter to you, then you have a blog post to read, don't you?

Bruno van Dooren, C++ MVP and general nice guy, blogged recently on "Is C++ still a viable language?" He makes lots of good points about interop, templates, and control. He points out that some UIs are a lot easier to build with C#. Then, out of the blue, he says mean things about VB. I know he's only joking, but I just felt I had to defend VB's honour.

Here's the thing. C#, it's mostly just VB with semicolons, you know? And that's not an insult, you shouldn't gasp when you read it. VB's a good and useful language. [Of course I mean VB.NET, come on, we're coming up to our fourth release, the default VB is VB.NET now.] It's no secret I do far more work in VB than in C#. Once in a blue moon I want to do something in VB that would be easier in C# (last week I wanted to delay hooking up button handlers until some initialization was in place, something the Handles keyword isn't going to do for me) and if I did more C# I would probably find the occasional thing that would be easier in VB. Big deal! I can always find a way to do those things anyway. What matters is the framework, and that's the same in VB, C#, or C++/CLI. I like the synactic sugar of Dispose=destructor more than the synactic sugar of "using" or "Using" but the underlying mechanism is the same in all three cases.

Herb updates us on the next C++ standard:

I'm happy to report that work on "C++0x", the much-anticipated Version 2.0 of the ISO C++ standard, has dramatically picked up steam over the past few months. The ISO C++ committee has now published the first partial draft of C++0x and plans to publish a complete public draft before the end of 2007.

As part of the push to get this done, the committee is having extra meetings, including one in Toronto in July. Hmmmm.....

You need to read Herb's blog post yourself for the details on what's in C++ 0x (Concepts, Garbage Collection, Memory Model for Concurrency, Concurrency Libraries) and what's not (Modules, Dynamic Libraries) with helpful links to even more details. This is our future -- and you can be sure, C++ has a future.

Eileen Rumwell is sponsoring a contest to send someone to Globewomen's annual conference, Global Summit of Women, in Berlin in June. Globewomen invite you to:

  • Join the premier gathering of women leaders focused on advancing women's economic opportunities globally
  • Be inspired by the energy, enthusiasm and expertise of the women decision-makers in business and government from around the world
  • Learn practical strategies to grow your career or your business
  • Share winning solutions and strategies with your peers
  • Be part of a global network of economic dynamos who will make changes in the 21st century global economy.

A 250 word essay about why you chose the technical field you did, and how you feel about it (man! 250 words is hardly anything! that's a challenge!) could get you airfare and accomodations so you can attend this seriously high-level get together. If you don't (or can't) win, consider attending anyway ... it sounds like fun!

I missed this article when it first appeared. Mary Jo Foley talked to Jason McConnell, me, and David Johnson about getting to all the new exciting Vista goodies, and how it's a bit easier from C++ because you can mix and match native and managed so simply. Watch for more guidance and guidelines on this from Microsoft coming soon.
