D3d hooking

So im trying to make a d3d hack, and i had a few questions.
1. In a debugger, where do i look for the address of the device and stuff?
2. Anyone have good tutorials on this stuff?
3. Is this the correct order of operation?

You can either use a pattern to find it or you can use olly to find it.

You need to understand how virtual functions are stored to find the device.

Set a breakpoint on Direct3DCreate9, the return is an instance to a class which contains the function CreateDevice, the last parameter is IDirect3DDevice9, that's what you're looking for. (:

There's a correct order of operations for everything.
