First thanks to you and George for hints.

I also tried PostMessage() API and keybd_event API but with no luck.
keybd_event worked for letters but can't send LEFT, UP, HOME DEL, etc. to another VFP application and PostMessage() didn't work at all (in any application).

P.S. I can do it by modifying the application where I try to send keys but I'd rather like to do general-purpose touchscreen keyboard with wscript.shell or postmessage or keybd_event.
