Some problem with DirectX code.

Ok, for some strange reason, Direct3D can't be created. I made a lib with a class inside it. everything compiled fine. i made a window and put the renderer in it. but for some reason, i get the message box that i programmed into it to tell me about Direct3D not being created.
Do you see ANYTHING wrong with this code? what do you think it could be that stops Direct3D9 from being created?
Direct3DCreate9() doesn't return a HRESULT, it returns an IDirect3D9*.
D3D_OK is 0. NULL is 0.
D3D_OK is 0. NULL is 0.
Quote:If successful, this function returns a pointer to an IDirect3D9 interface; otherwise, a NULL pointer is returned.
change the if statement to
if(!Cor_Direct3D9)
{
MessageBoxA(NULL,"Direct3D Could not be created","Error",MB_OK);
return 0;
}
Direct3DCreate9
Return Values
If successful, this function returns a pointer to an IDirect3D9 interface; otherwise, a NULL pointer is returned
Cor_Direct3D9 will either be a valid pointer or null
D3D_OK = S_OK
S_OK = 0x00000000L or NULL
if(!Cor_Direct3D9)
{
MessageBoxA(NULL,"Direct3D Could not be created","Error",MB_OK);
return 0;
}
Direct3DCreate9
Return Values
If successful, this function returns a pointer to an IDirect3D9 interface; otherwise, a NULL pointer is returned
Cor_Direct3D9 will either be a valid pointer or null
D3D_OK = S_OK
S_OK = 0x00000000L or NULL

thanks, i've decided to re-code the lib. I have done it over again and the device and Direct3D creates good but when i run the window with the lib in it also, i get like weird debug errorsa. like it compiles with out an error, but of course i get access vilolations and such. it points to this:
Do you guys see anything wrong with this code? cause i don't it should run and show a ren screen. But it doesn't show it. when i remove the function from the main loop and works fine. So what do I do?
void Cor_CDirect3D9Renderer::Cor_Sync(){ Cor_Direct3DDevice9->Clear(0,0,D3DCLEAR_TARGET,D3DCOLOR_XRGB(255,0,0),1.0f,1); if(Cor_Direct3DDevice9->BeginScene()) { Cor_Direct3DDevice9->EndScene(); } Cor_Direct3DDevice9->Present(NULL,NULL,NULL,NULL);}Do you guys see anything wrong with this code? cause i don't it should run and show a ren screen.
