Hi every one,
This is my first post... I desesperate to find the solution. This more that 3 days, I have been searching the net...
Here is what I have to do. I have to write an apllication that shows patterns on a small LCD (800x600). but The patterns has to be drawed with GDI in a backbuffer, ans has to be blittered on the screen in the shortest time.
in fact a triggered camera is acquiring on theses paterns.
I was using Directshow, but now as all 2D is deprecated, I try to do it with D3D.
Can someone show me a sample how to draw something on a surface in a backbuffer and show me how to blit it on the screen ?
Thx folks
