If I am wrong then please correct me as I am new in this. I have one thread which display image captured from webcam on a windows created using CreateWindowEx() function. Now when i execute my program I can see that my paint code (in WindowProc()) in never reached (called InvalidateRect() from child thread to redraw), checked using breakpoint.

Actually frame capture and display is being done in thread and I think because its in child thread and Window is in Main thread that is why its not able to call paint event.

Can you help me on this
