The situation is that a Delphi program, running in the background, calls a Clipper application at timed intervals. When the Clipper application is triggered a DOS window comes up then quickly closes when the program finishes. The porcess should take place without the user knowing it is even running. My questions are, Is there any way to surpress the DOS window from poping up? Is this a Delphi setting or something to be done in Clipper?
