$title = "My GUI UpDown"
GUICreate($title, -1, -1, -1, -1, $WS_SIZEBOX)

$input = GUICtrlCreateInput("2", 10, 10, 50, 20, $ES_NUMBER)
$updown = GUICtrlCreateUpdown($input)

GUISetState()

; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg()
    
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd

MsgBox(0, "Updown", GUICtrlRead($input))
