Windows Form App as parent, Directx as child??
I'm trying to write a windows Form Application in VS 2003 using c++. The Form should launch then a child to the form will execute using directX. My main problem is finding a HWND from the form that can be passed to the CreateWindowEx function as the parent handle.
I get as far as excuting the CreateDevice function and it returns D3DERR_INVALIDCALL. If anyone could point me in a good direction for finding out how to make this work, or what i'm doing wrong in my code it would be much appreciated. =)
here is the form.h file
Code:
