Hi alle Mann^^,
Ich habe mich mal bemüht eine UDF zumachen. 
Die UDF heißt _CountDown() (mir is kein anderer Name eingefallen 
)
sie erspart uns
For $for = 1 to 10
GUICtrlSetData($label, $for)
Sleep(1000)
Next
zu schreiben.
Hoffentlich gefällt euch die Func oder wißt was damit anzufangen.
Hier die UDF

; Function : _CountDown( controlID , Start number,End number,Sleep time,"Text for reason","Time units for example: s = seconds" )

Dim $countdown,$dE,$ds,$for,$ST,$GuiID_2
Func _CountDown($GuiID_2 = -1,$ds = 0,$dE = 100,$ST = 50,$countdown = "",$somoh = "" )
For $for = $ds to $dE
GUICtrlSetData($GuiID_2,$countdown & $for &$somoh)
Sleep($ST)
Next
EndFunc
Und hier mal ein Example:
