I think your talking about this for a window without a Title: >>>>>>>>>>>> Window Details <<<<<<<<<<<<< Title: Class: #XXXX Size >>>>>>>>>>>>>>>>>>> Start of Example: AutoItSetOption("WinTitleMatchMode", 4) ; Get the handle window for a $handle = WinGetHandle("classname=#XXXX") ; Send some text directly to this window's edit control ControlClick($handle, "", "Button3") End of example; Hope that helps .
