is there any way to draw in a MDI child form. As soon as i make a MDI window the directdraw functions throws a Graphicsexception in drawinternal(...) Does anyone know a work-around/solution for this?

The exception occurs in drawinternal, this is not a method of directdraw, but an internal directdraw method. I just don't see a way to show the graphics on the MDI child. Catching the exception just does not fix the problem: We can not adress the drawinternal function directly. By the way: when use a normal form the application runs fine.. the problem really lies in the combination MDI with directdraw..

You will have to handle the exception. There's no workaround for lost surfaces or loss of the drawing device that occurs when another window activates.
