Hi jugador,
When I insert your partial code into the help file example (_GUICtrlListBox_GetCount) then your script works fine :

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <GuiListBox.au3>
#include <MsgBoxConstants.au3>

Example()

Func Example()
    Local $idListBox

    ; Create GUI
     GUICreate("List Box Get Count", 400, 296)

    $idListBox = GUICtrlCreateList("", 2, 2, 396, 296)

    GUISetState(@SW_SHOW)

    ; Add strings
    _GUICtrlListBox_BeginUpdate($idListBox)
    For $iI = 1 To 9
        _GUICtrlListBox_AddString($idListBox, StringFormat("%03d : Random string", Random(1, 100, 1)))
    Next
    _GUICtrlListBox_EndUpdate($idListBox)

    ; Get item count
    MsgBox($MB_TOPMOST, "Information", "Item count: " & _GUICtrlListBox_GetCount($idListBox))

    ; ====================
    ; begin jugador script
    ; ====================
    $iTitle = "List Box Get Count"

    Local $hdlWindow = WinGetHandle($iTitle )
    Local $Ad_Mode = "[CLASS:ListBox; INSTANCE:1]"
    Local $hControl = ControlGetHandle($hdlWindow, "", $Ad_Mode)

    ;;this working
    _GUICtrlListBox_ClickItem($hControl, 1, "left",False)

    ;;but this return empty
    Local $iCnt = _GUICtrlListBox_GetCount($hControl)
    MsgBox($MB_SYSTEMMODAL, "jugador", "Column " & $iCnt)
    ; ==================
    ; end jugador script
    ; ==================

    ; Loop until the user exits.
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()
EndFunc   ;==>Example

I just changed your window title and  INSTANCE:4 to INSTANCE:1 to match the help file example.
If this doesn't help, could you please post your whole script (including Gui creation & other controls) so we can determine why it is not working at your place ?

pixelsearch Thanks.

I guess then it cannot be help.
It’s my office software and it’s not created using Autoit.
