I have used OWL and am now tryng to learn the MFC. This problem has me very frustrated. Just trying a "hello world" program from Windows MFC book by Jeff Prosise targeted at Visual C++. I use Borland 5.02. I use the include <mfc\afxwin.h> and get a compiler message "cannot open afx.h". afx.h is opened from afxwin.h which is obviously opened. any ideas???
