And you think we can guess what all that code is supposed to do, and what it isn't doing right?
the code shoot show a colored rotating cube i want to get rid of showing drawing it gives ugly effects i want double buffering i have no idea where / what i have to change in the code to that effect i got now : WS_POPUP | WS_MAXIMIZE how do i get fulscreen ?

Well you cannot expect anyone here to understand all that code in a few minutes. You need to narrow down where the problem is and gather some more information about what is happening. Your Window style should be based on
WS_OVERLAPPEDWINDOW, notWS_POPUP. Google for "set Window full screen". -

If you wrote the code to display the cube, then surely you can also remove it. If not, can you ask on the site where you procured the code from? Grabbing code from other sites, blindly throwing it into a compiler, and then wondering why it doesn't work hardly defines the software development process.

i use the mdsn site + goolge for info yes its a lot of code i wrote it myself and i don't expect the error's to be fount fast the problem whit my code is that you see the drawing of the triangles over eatch other i think i have to change somthing in WM_PAINT but i m not sure
