Hello,

I have the following script: 

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $start



;=======================================
;Asteapta semnal pentru CAPTURA 1
;=======================================



;=======================================
;Definire coordonate captura
;=======================================

Global $xs =    GUICtrlRead ($startx)
Global $ys =    GUICtrlRead ($starty)
Global $xe =    GUICtrlRead ($endx)
Global $ye =    GUICtrlRead ($endy)

;=======================================
;Captura prima poza
;=======================================

    Local $hBmp
    $hBmp = _ScreenCapture_Capture(@scriptdir & "\1.jpg",$xs,$ys,$xe,$ye)

;=======================================
;Realizeaza prima citire + trimite datele in casuta + afiseaza imaginea in GUI
;=======================================
_GDIPlus_Startup()
    $hex_avColor_1 = Screen_Area_Average_Color($xs,$ys,$xe,$ye)
    Guictrlsetdata ($value1,$hex_avColor_1/10000  )






        Case $live1


        While 2
        sleep (100)
        If $nMsg = $stop then exitloop
        Global $xs =    GUICtrlRead ($startx)
        Global $ys =    GUICtrlRead ($starty)
        Global $xe =    GUICtrlRead ($endx)
        Global $ye =    GUICtrlRead ($endy)

        Local $hBmp
        $hBmp = _ScreenCapture_Capture(@scriptdir & "\1.jpg",$xs,$ys,$xe,$ye)
        GUICtrlSetImage ($p1,"1.jpg" )

        _GDIPlus_Startup()
    $hex_avColor_1 = Screen_Area_Average_Color($xs,$ys,$xe,$ye)
Guictrlsetdata ($val1,$hex_avColor_1/10000  )
    ConsoleWrite($hex_avColor_1 & @CRLF)
        Wend



        Case $stop
        
        Exitloop 2



    EndSwitch
WEnd

 

When I press $live1 a while loop will start and will run but when i press $stop i want the loop from $live1 to stop, but it doesnt work. If I click $stop nothing happens.

Anybody knows why?

is used instead of a normal sleep. The returned messageID must be handled in scriptcode (already done by me)
