.NET Forum / Languages / Managed C++ / June 2007Will 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~ >Does VS Orcas still has VC++ Yes >do you think that VC++ will face out by >dotnet or Java ? No more than it has already. >Can C# support standard or Win32 C/C++ class lib dll and COM ? I'm not sure what you're asking there. >Can dotnet and Java do device IO control with drivers ? Is that, can you write drivers with .Net or Java? If so, I'm pretty sure the answer is no. >Can dotnet and Java avoid disassembly for commercial software development , > and how about their low performance ? 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.

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. >>Can C# support standard or Win32 C/C++ class lib dll and COM ? > I'm not sure what you're asking there. 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. >>Can dotnet and Java do device IO control with drivers ? > 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.

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. > How does this work?

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> Regards, Will >> How does this work?

Can't think of any others they might tolerate. > Regards, > Will > Hi I have many questions > > Does VS Orcas still has VC++ <snip> 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...

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). http://msdn.microsoft.com/msdnmag/ Free MagazinesGet these publications absolutely FREE for up to 12 months.
