}That's my code... im working out of a book so sorry i'm not sure what i can and can't delete to make it shorter. I need to compile it and whenever i do these are the errors i get...

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========Im not sure what i'm supposed to do now. For the record i'm working out of a directX9 book but i installed the directx10 SDK. does that matter? and what do i do? I've already added D3D9.LIB into my additional dependencies under properties and declared it at the top of my code... Thanks and PLEASE help.
