Hi Werner,

The easiest way to deal with this is to first load foxtools. If you're using the main VFP window, retrieve it's window handle using the MainhWnd() function, other use _WHToHwnd(_WFindTitl(ThisForm.Caption)) to get that. Assuming that you've main the active VFP window handle (either _SCREEN's or Form) as a property of the object (in the example a form) that has the timer, then the following does what you need:

DECLARE INTEGER GetForegroundWindow IN Win32API
LOCAL lnhWnd
lnhWnd = GetForegroundWindow()
IF lnhWnd # = ThisForm.hWnd
  * VFP's running
ELSE
  * It's something else.
ENDIF
