StdAfx + Header file - Order of inclusion in MFC application
Solution 1:
This link must give you some clue. Purpose of stdafx.h
The lines defined before the
#include "stdafx.h" are ignored by the compiler. So if you want to actually include those files then you need to include them after the #include "stdafx.h".
Hope it is clear.
Solution 2:
In addition to ckv's answer, it makes little sense to include header files before "stdafx.h" as any non-trivial header file will contain framework types that are included there (e.g. any MFC types).
