C++: Help with direct3d code

[abcdefg]

Okay Im really having trouble getting this to work properly. There are no errors I could find after I made a crude message handler. I didnt include that code. Why is the texture not being drawn? did I not set a needed texture stage?
Thanks to all those that take the time to help.
