DirectX 3D

When I use MFC appwizard to generate boiler plate app and then #include "d3drmwin.h" I get an error suggesting that I have tried to include windows.h twice.

Anybody got any clues?

This shouldn't be a problem since windows.h has this at the top of it :

#ifndef _WINDOWS_
#define _WINDOWS_

I went through those headers and it's really a mess.
Lot's of nested includes but I guess that can be difficult to avoid.
Personally, I try to do the protection outside the header, not in it.

Anyway, could you be more specific about the error condition you are getting ?

I have added two lines of code in the StdAfx.h file.

#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers

#define INITGUID // these lines added

#include "d3drmwin.h" // these lines added.

#include <afxwin.h> // MFC core and standard components




And got the error.


c:\program files\microsoft visual studio\vc98\mfc\include\afxv_w32.h(14) :
fatal error C1189: #error :
WINDOWS.H already included.
MFC apps must not #include <windows.h>


I hope this helps clear up the problem.


Thanks

Try placing the d3drmwin.h include after afxwin.h
Also, the is a Direct-X library for use with MFC at
http://www.dxfc.com that might be helpful.
