Direct3D8 Spinning Pyrimid

If you are a newbie to either DirectX8 or C++ then this is for you! It is a simple and fully commented program which uses DirectX8 to render a spinning triangle in fullscreen mode. This is my 1st C++/DX8 program and only my 3rd ever C++ program, so while I can ensure it's pretty simple, it might not be perfect, so please give me some help on improving it. If it's interesting/useful to you please vote for me because I worked very hard on this.
