Old VC++ projects

Bonjour!

Here I’ve got bunch of projects created with an older version of VC++. When I’m trying to open any of them up with VC++ 6, it gives a message telling that it’ll convert the project into the new VC format, and after it do that I can compile, debug and do all of that. But the class view info is missing. So I created an empty Win32 App and added all the C++ files in those projects into it, and tried to compile the thing. But it won’t compile.
The linker errors are:

Code:

error LNK2001: unresolved external symbol __endthreadex error LNK2001: unresolved external symbol __beginthreadex

The only VC header the files include is <afxwin.h>.

Can anyone tell me please the stuff I have to do to make it compile?

Thanks a lot.
