hello, i want to detect if this window: is exists. so i used Au3Info to get the CLASS name and this is the CLASS name that is unique only for this window: so i did this test: While 1 $state = WinExists("[CLASS:DolphinEmuWnd]") ToolTip($state) Sleep(1000) WEnd and the test failed. WinExists does not return 1 when the window is exists. what i did wrong? thanks for helpers!
