I have a dialog app where I'd like to have a control that is direct3d
rendered. So, when this control's window is created I call an
CreateDevice() as below. But, it always fails with the error code
D3DERR_INVALIDCALL (0x8876086c). [...]Standard questions apply:
- what versoin of the SDK are you using?
September 2006

- Debug runtime installed?
Yes

- Debug runtime selected?
Yes

- What does the debug output say when you run your app?
Now this is interesting... I turned the debug up to the max in the
"DirectX Properties" app and now I see this:
Direct3D9: (INFO) :Direct3D9 Debug Runtime selected.
Direct3D9: (ERROR) :Neither hDeviceWindow nor Focus window specified.
CreateDevice Failed.

I see my problem now.. The focus window is NULL, so my window creation
code hadn't been run yet.
Fixed! Thanks!

- All HRESULTs checked?
Yes, the HRESULT is the error code I'm posting (see code)

Thanks for your help. If you haven't seen my reply to my own first post
where I mention that half the directx SDK utilties aren't running,
please take a look at it and see if you can't recognize the issue. I
have tried reinstalling the SDK and restarting the computer, but the
problem remains.

Thanks,
