Learn notes, haven't seen it yet, temporarily store you if you want to express 2D in 3D, just use what I said
If you are pure 2D
You can see DDRAW information in D7, also support in D9.
If you have to use D3D
There is IDirect3dsurface9 in D9, you can check it to see the usage
Give a small example, very simple to change, and DDRAW is almost
#include
#include

LPDIRECT3DDEVICE9 PD3DDEVICE = NULL; // D3D9 device object interface
