}
it goes to "invalid call" i have a geforce 4 igp, so you cant tell me that it wont accept the a8r8g8b8, i also tried x8r8g8b8.. what am i doing wrong, cuz this is the same code from within the book, and it errors out

since you''re requesting full screen, you also need to specify the back buffer''s width and height.
Additionally, the debug Direct3D runtime will have told you WHY an invalid call error was returned...
