Looks good. If I might make a suggestion. You can simplify a lot of your code into functions instead of repeating it. Opt("GUIOnEventMode", 1) $EXIT = GUICtrlCreateMenuItem("Exit", $FILE) GUICtrlSetOnEvent($EXIT, "_Exit") .... Case $Msg = $GUI_EVENT_CLOSE _Exit() .............................. Case $Msg = $SAVEAS _Save() Case $Msg = $SAVE And $FILEOPENED = 0 _Save() .............................. Func _Save() GUICtrlSetState($EDITBOX, $GUI_DISABLE) SaveAs() $FILEOPENED = 1 GUICtrlSetState($EDITBOX, $GUI_ENABLE) EndFunc ;==>_Save Func _Exit() If _GUICtrlEdit_CanUndo($EDITBOX) Then $SAVECHANGES = MsgBox(35, "Text Editor", "Your original file has been modified." & @CRLF & "Would you like to save changes to it?") If $SAVECHANGES = 6 And $FILEOPENED = 0 Then SaveAs() Exit EndIf If $SAVECHANGES = 6 And $FILEOPENED = 1 Then FileDelete($FILEOPEN) FileWrite($FILEOPEN, GUICtrlRead($EDITBOX)) Exit EndIf If $SAVECHANGES = 7 Then Exit EndIf EndIf If Not _GUICtrlEdit_CanUndo($EDITBOX) Then Exit EndFunc ;==>_Exit
