Hey I''m trying to make a DirectX application but am having troubles initializing directx. It should be making a fullscreen application but it stays windowed I''m pretty sure my CreateDevice is failing

  
// Create the d3d object

	g_d3d = Direct3DCreate8(D3D_SDK_VERSION);

	// Get adapter display mode

	D3DDISPLAYMODE d3ddm;
	g_d3d->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3ddm);

	// Set the presentation parameters

	D3DPRESENT_PARAMETERS d3dpp;
	d3dpp.BackBufferWidth = 800;
	d3dpp.BackBufferHeight = 600;
	d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8;;
	d3dpp.hDeviceWindow = hWnd;
	d3dpp.Windowed   = FALSE;
	d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;

	// Create the d3d device

	g_d3d->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_REF, hWnd,
                                  D3DCREATE_SOFTWARE_VERTEXPROCESSING,
                                  &d3dpp, &g_d3ddev);

Try setting d3dpp to all zeros before filling in the values.

e.g. ZeroMemory(&d3dpp,sizeof(d3dpp));

It may be that there is garbage in the Fullscreen_RefreshRateInhz field that is causing the thing to fail.

You should also check the result code of the CreateDevice call (or at least wrap it with "if (FAILED(...)))". That way you''ll know if it fails.
