>I'm sending some commands to another application via DDE. When I did this with this particular application through VB, I found I needed to 'AppActivate' the DDE server in order for the commands to complete smoothly. I cannot seem to find an equivalent operation in VFP5 (makes a specified program the foreground application, while the VFP app drops to the background).

Either SetForegroundWindow() or BringWindowToTop() should work. Both require the handle of the window that you desire to activate.
