This topic lists features that were discontinued starting in version 3.0 of the MFC library. Many of the changes result from similar changes in Win32.
Since calls to CGdiObject::UnrealizeObject are common in programs written for Windows version 3.x, yet are now unnecessary, this member function is retained for backward compatibility. It now always returns a nonzero value, without making an underlying Win32 function call. Calls to CGdiObject::UnrealizeObject should not be made in new Win32 programs and should be removed from existing programs eventually.
If your program needs this functionality, you should create a member function that calls your AbortProc
callback function directly.
You should now link with NAFXCW.LIB or NAFXCWD.LIB with no loss in capability or content from projects that previously used NAFXCR.LIB or NAFXCRD.LIB.
