#error WINDOWS.H already included. MFC apps must not #include <windows.h>

Question

I am getting #error WINDOWS.H already included. MFC apps must not #include windows.h But i dont know how do i find out because of which file this is happening

Thanks

Answer 1

Try turning on "Show Includes" in the projects settings (C/C++ -> Advanced). This show give you an indication of what header files are included and in what order - you should be able to trace back from there

Answer 2

Change the include order, and include afx < headers > before the others
