I'm praticing to program with Visual C++ from someone's book using Visual C++ 4.0.
When I use Visual C++ 5.0, the program doesn't work.
It seem to me that the header and library from the author, compiled with Visual C++ 4.0.
Is there any chance that the header and library using codes that only works for older version of mfc (mfc40) ?
How can we recompile a library and header files ?
