Unhandled Exception error with DirectX Program

[NintendoFreak91788]

Hi
I'm trying to create a simple Direct X Application that displays a wireframe sphere. When I try to compile and run, I get the following error in a pop-up window:

Unhandled exception at 0x00d71bae in KatieHanlonWeek3Lab.exe: 0xC0000005: Access violation reading location 0x00000000.

I have no idea what it's about. I am doing this for a class assignment and we were given pieces of code to insert. The only error I can think of is me pasting them in the wrong place. The code in it's entirety is attached to this post in "Winmain.cpp". I have specified in the comments which pieces of code were pasted from the assignment.

If anyone could help me out, that would be great. Thanks in advance.

Katie
