Hi there, I tried: HotKeySet ( "{F8}", "_MouseClickPlus") While 1 Sleep ( 100 ) WEnd Func _MouseClickPlus ( ) Local $Window = "Naamloos - Kladblok" Local $MK_SCROLL = 0x020A DllCall("user32.dll", "int", "SendMessage", _ "hwnd", WinGetHandle( $Window ), _ "int", $MK_SCROLL, _ "int", 0, _ "long", 0 ) ConsoleWrite ( @Error & " " ) EndFunc And the Error returned = 0. Because this is the first time I use a DllCall I don't know how to fix this... Why won't my notepad
