Excluding the Update Region

The ExcludeUpdateRgn function excludes the update region from the clipping region for the display DC. This function is useful when drawing in a window other than when a WM_PAINT message is processing. It prevents drawing in the areas that will be updated during the next WM_PAINT message.
