Got empty value using GUICtrlComboBoxEx_GetItemText

[Raq]

Hello!

 I would like to ask for your help, regarding getting the value of the combo box in a desktop application.

I tried the codes below, but I got an empty value. I am really asking for your help if how can I display the value of the combox.

Func CheckStockCode()
    $stockWin = Call(OpenClass_32770)
    Sleep(4000)
    Local $sText
    _GUICtrlComboBoxEx_GetItemText(4029, 1, $sText)
    MsgBox(1, "OUTPUT", $sText)
EndFunc   ;==>CheckStockCode

 Thanks in advance,

Raq
