Just starting, and having a problem with rending a triangle(DX 8.1)

EDIT: Thanks for the tag help. The problem could be anywhere, so I added all of the code. It isn't commented very well, or very well structured, as I tend to do that after I hit a landmark(the first being actual rendering). Basically, I just get a huge red screen, and that's it. The debugger sys that nothing is wrong, so I think that it may just be a logic error of mine. The code should render a triangle, with a material added to it, but it just stays invisible. If anyone decides to help, I will be eternally grateful.

I dont know if this is linked to your problem but, you set your back buffer to a much higher size than your window size.

This could be causing your problem but, if not it still is draining memory that could be used elsewhere.
