The WinExists function is used to check if a window exists.
If you got multiple windows, it can be more secure to perform the check using a window handle, rather than checking directly.
Normally you likely won't need to check for the existence of a window, but it can be a good idea, if there's a possibility that the window has been closed, by someone who is using the computer – either on purpose or by accident. Otherwise your script could, for example, start clicking unintended places.
Returns 1 on success and 0 on failure.
|Title||The title of the window.||Required|
|Text||The text of the window to read.||Optional|
If WinExists("[CLASS:Notepad]") Then MsgBox(0, "", "Window exists") EndIf
