Hi Hilmar,

Yes, my VFP app runs FoxPro 2.5 DOS app with RUN /N1 ... command.
But then I need to minimize that FP DOS window and set its priority to low. (analog to DOS command

START /MIN /LOW foxprox.exe myprog.fxp )

I have the window handle and its Thread Process Id.
I found out that to set priority to low I can use SetThreadPriority() API function with THREAD_PRIORITY_LOWEST constant but I can't find that constant value and can't find the .H file to see how it is declared.
