Do you get any kind of traceback when you start a process that way? There's not much info to go on.

Your device context handle might not be valid even if you make it an int. hth Roger "arN" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi ! > > I'm a Java developper and I wish to make a capture of an offscreen window > (on WinXP).
