[Burgaud]

I have no idea what these two functions do..
Please explain.

Sample script direct from the help file:

#include <GUIConstantsEx.au3>

Example()

Func Example()

    GUICreate("GUICtrlCreateDummy", 250, 200, 100, 200)
    GUISetBkColor(0x00E0FFFF) ; will change background color

    Local $idUser = GUICtrlCreateDummy()
    Local $idButton_Event = GUICtrlCreateButton("event", 75, 170, 70, 20)
    Local $idButton_Cancel = GUICtrlCreateButton("Cancel", 150, 170, 70, 20)
    GUISetState(@SW_SHOW)

    Local $idMsg
    ; Loop until the user exits.
    Do
        $idMsg = GUIGetMsg()

        Select
            Case $idMsg = $idButton_Event
                GUICtrlSendToDummy($idUser)
            Case $idMsg = $idButton_Cancel
                GUICtrlSendToDummy($idUser)
            Case $idMsg = $idUser
                ; special action before closing
                ; ...
                Exit
        EndSelect
    Until $idMsg = $GUI_EVENT_CLOSE
EndFunc   ;==>Example

 

What does GUICtrlSendToDummy($idUser) actually do?

I would want to "group" hide, disable, etc together with a simple 3 line For .. Next loop.
