Like double-buffering we write the windows contents to an image and finally transfer the entire image to the device context. Additionally we keep the image between the paint events and rebuild the image only if necessary (data to show has changed). When the frame containing your view becomes invisible (frame iconized or hidden) you should use the ReleaseBuffer() method to decrease the memory footprint of the program.
