I've been staring at this source I wrote but can't find the problem. It starts up fine in windowed mode but when I change it to fullscreen, I get the messagebox errors. As I said, when I run windowed it's fine but when I turn on fullscreen, the errors comes up: "Could not initialize 3D card!" Obviously, the createdevice call is failing. I think it has to do w/ one of the parameters in d3dpp but I'm not sure which one. I'm using DX9 for the coding. I think I've been staring at the code too long, I just can't find the problem. Thanks for any help you can give.
int InitD3DDevice(HWND hWndTarget, int Width, int Height, BOOL bWindowed,
D3DFORMAT FullScreenFormat, LPDIRECT3D9 pD3D, LPDIRECT3DDEVICE9* ppDevice)

D3DDISPLAYMODE d3ddm;
HRESULT result = 0;
if(*ppDevice)
(*ppDevice)->Release();
ZeroMemory(&d3dpp, sizeof(D3DPRESENT_PARAMETERS));
result = pD3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3ddm);
if(FAILED(result))
{
MessageBox(g_hWndMain, "Could not get 3D card!", "Error", MB_OK | MB_ICONINFORMATION);
return E_FAIL;
}
if(bWindowed)
