GEOSoft Posted December 28, 2007 Share Posted December 28, 2007 Tried that, did: $Online = _GUICtrlListCount($ListBox) If $Online = 0 Then GUICtrlSetImage($nListview, "shell32.dll", -110) Else GUICtrlSetImage($nListview, "shell32.dll", -138) EndIfTry If $Online < 0 Then IIRC the function returns -1 when there are no items.

Nahuel Posted December 28, 2007 Share Posted December 28, 2007 (edited) And the problem is.... This works just fine #Include <GuiListBox.au3> Global $hGUI, $hListBox ; Create GUI $hGUI = GUICreate("(Internal) List Box Get Count", 400, 296) $hListBox = GUICtrlCreateList("", 2, 2, 396, 296) GUISetState() ; Get item count $count=_GUICtrlListBox_GetCount ($hListBox) MsgBox (4160, "Information", "Item count: " & $count) If $count=0 Then MsgBox(0,"","it's empty") ; Loop until user exits Do Until GUIGetMsg() = $GUI_EVENT_CLOSE Exit -edit-: Just noticed he used a different UDF.

GaryFrost Posted December 28, 2007 Share Posted December 28, 2007 Is the listbox created by AutoIt or an external application?
