Nevermind, I'm good.

Turns out that refreshing the matrices every draw doesn't quite work appropriately.

Anyone out there help me out?

I believe that it has something to do with the speed at which the device clears the screen before painting the new one. If i put a breakpoint on the this.invalidate line and then hold f5 to just continue the program it works perfectly.

Looking at msdn and a few other things, the invalidate method has to wait for the messages or something to stop or you should make the messages or something stop, i personally have no idea, so i am hoping someone can help me. Once it get this problem solved i should be good.

Cheers guys

Hossainiir,

not sure what you mean by PIX? could you elaborate?


thanks adt7, but not sure what i should be doing for drawing.

i uncommented the drawprimitives section and it still just shows a blank screen.

Is there something i am missing?

Thank you very much for your help unbird. It no longer throws this error.

However, the next question i have is why doesn't it show the cube?

Any help you could provide would be much appreciated.
