Migrating codes to VC++ . NET 2005 from VC++ 6.0

[Guest]

I wonder if the transistion from the project written in VC++ 6.0 to VC++ .NET
requires a lot of code changes (if any) if I compile the project in native
code (or unmanaged code) without using the CLR in VC++ .NET.

Thanks for your feedback.

That depends a very great deal on your code. The only way to find out for
your code base is to try it.

Thanks for your prompt reply, Carl. Is there an online source that points me
to the major differences in syntax between VC++ 6.0 and VC++ 8.0 (VC++ .NET
2005)? I meant the Standard C++ syntax, not to include the new syntax
C++/CLI, managed extentions in the .NET. Or could you point out some major
differences if you know any?

Thanks.

Well, all the differences you will get are because of bugs or non-conformant
behaviour in VC6. Therefore, I don't know if the term "differences in
syntax" is appropriate. Anywat, here you have :

Also see concerning changes in the CRT :

I've blogged on some of the issues I faced here :- http://blog.voidnish.com/

Thanks for your reply. Do you or anyone know how to compile native C++ code
(written in VC++ 6.0) in .NET 2005? Any switch or command do I need to know?
Is it possible to compile native code in .NET without involving/mixing with
..NET stuff (like clr, ect).?

Thanks.

No extra switch needed. Open your VC6 project in VC 8 and it'll ask you if
you want to migrate the project to the new version. Click yes - do a
rebuild-all and watch the fun ;-)

LOL... fun, yeah that's what I'd call it )

That's why subroutines in C are called FUNctions...
