>Yes, if they don't change it I do know the caption of the application.

OK, I'll post here one simple example that don't care about Caption, but when I go home I'll try to post other example that will wait of external application to run and then send keys:

DECLARE Integer Sleep IN WIN32API INTEGER lnPeriod
RUN /N NotePad
Sleep(1000) && One second
oWSH = CREATEOBJECT([WScript.Shell])
oWSH.SendKeys([This is a test])
