Will VC++ face out ?

Hi I have many questions

Does VS Orcas still has VC++ , do you think that VC++ will face out by
dotnet or Java ?

Can C# support standard or Win32 C/C++ class lib dll and COM ?

Can dotnet and Java do device IO control with drivers ?

Can dotnet and Java avoid disassembly for commercial software development ,
and how about their low performance ?

Thank for your teaching~

No more than it has already.

I'm not sure what you're asking there.

Is that, can you write drivers with .Net or Java? If so, I'm pretty
sure the answer is no.

You can get obfuscators for them.

As for performance, it depends on precisely what you're doing. For
some situations you may not notice any difference, but for others it
may be highly significant.

And it will have for some time to come. there is a renewed push for native
code within Microsoft, and all major products incl windows, SQL server etc
are still built using VC++

Probably a bit more. Anything that can efficiently run on the .NET framework
will be developed in C# or (god forbid ;-)) VB.NET.
I like C++ as much as the next C++ MVP, but I use C# whenever it is
feasible. Use the right tool for the job.

C# can use DLLs that export C style functions. static libraries or C++ class
libraries (whether dynamic or static) cannot be used.
COM interop is usually not a big deal, but you will have a performance
impact and it is harder to marshal non trivial datatypes.
Is that, can you write drivers with .Net or Java? If so, I'm pretty
sure the answer is no.

Indeed you can't. The UMDF (user mode driver foundation) allows you to write
bus drivers in user mode (for example USB or firewire). It is not impossible
that one day, these will be possible to write in C#.
But anything kernel related will be C or C++ for the forseeable future.

Before asking those kind of questions, just ask yourself :

With what tool do you think that

1) Windows
2) Office
3) The .NET framework

are compiled within Microsoft?

Then you'll realize that they CAN'T abandon VC in any forseeable
future...

Adding to what others have told you...
Check out recent issues of MSDN Magazine online to see significant
enhancements to C++ class libraries such as MFC, which will arrive with
Visual Studio 2008 (new name for Orcas).

How does this work? I've heard for years how they're going to be eating
their own dogfood.

There are plenty of major "Windows components" built on .NET, especially in
Vista, but those are just features delivered with the install. The OS
itself is pure native.

So, they do eat their .NET, and their C++ as well.

No fear of C++ being phased out in the foreseeable future.

What compiler do you think they used to compile Office, say?

<speculation>
What fate do you think might befall one of their C++ developers who might
choose a compiler from another company?
</speculation>

I suspect the Intel compiler of being acceptable. Can't think of any others
they might tolerate.
