Definite claim of C++0x support in VS2010 is wonderful news; I can't wait to play with the lambdas.

A question, though: will the rest of C++0x be coming in the final version? Specifically, concepts?

re: Visual Studio 2010 CTP released

phrosty — Tue, 28 Oct 2008 21:22:23 GMT

the source code is fairly clean and easy to understand, but i'd really like to see some full documentation of the parallel library.

thanks for the renewed native C++ effort guys, it really means a lot!

also, will we be getting lock-free stack/queue? I know it's a little tougher to make due to no GC, but it's definitely still doable would be really cool :)

Very glad to hear this! Of course, everyone is going to have their own feature that they want to know about. Mine is Unicode string constants:

const char32_t s[] = U"This is a UTF-32 string.";

Any chance of them finding their way in?

Not all C++0x features will be implemented in VC10. In particular, concepts will definitely NOT be implemented in VC10. (Concepts were JUST finalized and integrated into the Working Paper; also, they're the largest C++0x feature by far.)

Is it true that IDE will be rewritten in WPF? If so, why?

"Is it true that IDE will be rewritten in WPF? If so, why?"

If so, WTF?! I'd say. Guys, are you completely taken over by the marketing BS managers? How about "Hello, Kitty" theme for cute development? The last decent version of IDE was v.6. Every new version is twice slower, has twice as many bugs - beta quality at best. So some genius decided to make a new version instead of decent service pack? Same goes to Vista, and the whole trend. Looks like a good time to start learning some more fruitful - Apples, Cocoas, etc.

David — Wed, 29 Oct 2008 20:04:03 GMT

I have downloaded the visual studio 2010 ctp. As far as I can tell, I am disappointed to find out that the IDE is even slower than VS 2008. The class view is slow and buggy (base classes such as CView, CEdit, etc are even listed for a new MDI program). There is also no improvement on the gui design (I am looking for simpler gui layout such as automatic alignment like in VC#).

If the final version of VS2010 is like this, I will stick to VS2008.

re: Visual Studio 2010 CTP released

SvenC — Wed, 29 Oct 2008 20:48:40 GMT

Hi David,

are you comparing both versions running as a VPC or do you compare VS2008 running on your host and VS2010 in your VPC?

But if it is really true that the whole IDE is rewritten with WPF we cannot say anything on how such a fundamental change will influence performance.

If that change really happens this will be a heavy real world test for the performance possibilities of WPF. Please, surprise us positively ;-)

@SvenC:

"we cannot say anything on how such a fundamental change will influence performance."

We can say that WPF miserably failed in the marketplace so far, at least partially due to horrible perf.

Even if the perceived speed of operation of the new IDE will be similiar to VS2008, the memory requirements will be certainly much larger.

Can I just say congratulations on removing the SxS requirement on the runtime. It has caused no end of pain for us when dealing with thirdparty libraries and product deployment.

re: Visual Studio 2010 CTP released

pingpong — Thu, 30 Oct 2008 16:07:56 GMT

It definitely seems that IDE is going WPF - see this stream around 01:28:00. (The VS2010 bits available today aren't fully WPFized yet.)

ChrisLux — Sat, 01 Nov 2008 20:37:08 GMT

hi,

very nice talk about the Visual Studio 2010 features.

But one question that bugs me since VS 2005 is: When will the default runtime iterator range checking for release builds be completely disabled. There is quite a large performance impact when using the current default setting. In every project i use and every dependency i have to set _SECURE_SCL=0 to disable it for release builds.

So will this be disabled by default for release builds in VS 10?

re: Visual Studio 2010 CTP released

grumpy — Sat, 01 Nov 2008 22:36:18 GMT

ChrisLux:

Don't count on that ever happening. You're not the first to argue for this, but it's security!

Never mind that the net effect of this "feature" is to drive a lot of people away from the STL entirely, and back to C-isms like raw arrays and char* for strings thus probably causing *less* robust and secure software to be written, or that the way it's implemented is just *begging* for subtle ODR violations, especially when linking to 3rd party libs, causing fun fun unpredictable crashes.

The important thing is that the VC++ team can *say* that they take security seriously. Look, we've got a bullet-point feature saying we've made a specially secure version of the standard library! Can we have a raise now please? ;)

(Seriously though, couldn't you have found a less intrusive way of enabling this stuff? An extra template argument with a default value, perhaps? Something that could be toggled on and off locally, and didn't break the ODR rule if you link to a library or translation unit that had a different setting)

I think this one is a lost cause. At least if you use property sheets it's fairly easy to define this macro yourself for all your projects. :)

Not an optimal solution, but I doubt we're likely to see the situation improved any time soon.

Ten years ago, "proprietary" was a magic word that, when invoked, could completely freeze Microsoft. Once something was proprietary, *nothing* could be changed, lest competing products might start actually competing.

Today, "security" has taken on that role. Once the magic word has been invoked, it's impossible to get Microsoft to reconsider or backtrack. It doesn't matter whether what they're doing is actually secure, but if they *say* it is, that's the end of the discussion. You can't argue with the magic word.

Apart from that, VS2k10 looks pretty sweet, and I'm having good fun with the new VC++ build engine and the C++0x features. Nice job there. :)

I downloaded the .r files from exe part 1 to 11. When running the exe to extract the rest of the files. Reaching .part10.rar, an error appears.

CRC failed in VisualStudio2010CTP.vhd, i re-ran the exe and it errors out a the same .rar.

I re-downloaded *.part10.rar again, and try again, same issue.

Any feed back? Thank you.

We posted another thread specifically on the C++0x features implemented in our CTP and our thoughts about our future C++0x work (int19h: I see you have already posted there) http://blogs.msdn.com/vcblog/archive/2008/10/28/lambdas-auto-and-static-assert-c-0x-features-in-vc10-part-1.aspx; can I point others at this other post for C++0x questions - so we answer them all in one place.

Thanks

Ayman Shoukry — Fri, 07 Nov 2008 02:37:40 GMT

Regarding the deployment questions, we moved away from using the windows SxS model. We are using a similar mechanism to the VS2003 deployment model. Per previous versions, we will sport both static & dynamic linking to the CRT. For dynamic linking, the loading sequence will be:

[Updated: Damien 10/20/2009]

1) Search in the local directory (AppLocal)

2) If not found, search for the CRT in the System directory (System32)

3) If not found, search in the path.

The CTP inludes a detailed walkthrough of the deployment options

Thanks,

Ayman

I've seen lots of new things added to C++ IDE with VS 2008 and VS 2010.

Is there any chance you will be able to blog about the speed improvement in compiled code? This is of primary importance to us and much much less important than improvements in the IDE.

re: Visual Studio 2010 CTP released

Ted. — Sun, 09 Nov 2008 20:06:47 GMT

Ayman, your post seems to imply that a VC 2010 compiled app searches the system32 folder first before the application local folder when looking for CRT and MFC DLLs.

Is this truly the case? In my tests, it always looks for the application local folder first.

re: Visual Studio 2010 CTP released

Ayman Shoukry — Mon, 10 Nov 2008 02:59:38 GMT

Ted, you are right. I switched the order when I posted the last reply.

The general order is:

1) Search for the CRT/MFC in the directory where the application is loaded

2) If not found, search in the system directory

3) If not found, search in the directories listed in the PATH environment variable.

Thanks for pointing this out Ted.

Thanks,

Ayman

This would be a breaking API change for the purpose of template specialization, and template template arguments. The result would simply not be Standard-compliant.
