oh ,     then i think i can't do this..   i thought that the hWnd was always the same for an app,   for example,  my script opens the windows media player,  or performs a scan with norton antivirus,     so i thought that if i found out what's their hWnd,   i could always kill those apps...     
but now, as you say,  the hWnd is different every-time they run,  then is far more complicated than i thought
