May be there is another way to do this like to using SendMessage API call with WM_DESTROY message. If I right understood, the application window will close after receiving this message. I didn't tried this because can't find the value of WM_DESTROY message, but may be someone will have more luck ;) >I've written a couple of functions which are available in the Files/Win32 & Other APIs section > As to shutting down the application, that can be a rather tricky business. If the application was already active when VFP started up, I don't know if it's possible.
