Thread: direct draw basics...need some help

alright, i finally decided to seriously take on directx. anyways, i am trying to just set up a basic window (i'm not trying to create any surfaces yet or anything). heres the coding im having trouble with:

Code:

lpdd->QueryInterface(IID_IDirectDraw4,(LPVOID *)&lpdd4)

i'm using msvc++ 6.0, and the error i get is:
error C2065: 'IID_IDirectDraw4' : undeclared identifier

and this is killing me. ive got everything i need, or so i think. ive created the lpdd and lpdd4 objects, ive included the ddraw.lib and ddraw.h in my project. if anyone could help, i would really really appreciate it. thanks alot.

Your function should compile, but won't link if you haven't linked to dxguid.lib. What version of the DX sdk do you have ? The code below compiles and links -

Code:

#pragma comment(lib,"ddraw.lib")
#pragma comment(lib,"dxguid.lib")

#include <ddraw.h>


LPDIRECTDRAW lpDD;
LPDIRECTDRAW4 lpDD4;
int main(){

	DirectDrawCreate(0,&lpDD,NULL);
	lpDD->QueryInterface(IID_IDirectDraw4,(LPVOID*)&lpDD4);

	lpDD->Release();
	//Do stuff 
	lpDD4->Release();
	

	return 0;
}

Also, you may want ditch whatever you're learning this from for something more up to date, as the later versions of Direct X provide an easier method to obtain the correct interface (even though this way should still work).

ugh...none of its working...i linked to the dxguid.lib library...everything. this is so aggrivating..anyways thanks for your help
