chssoccer Posted December 28, 2007 Posted December 28, 2007 How can I tell if a listbox is empty using an If statement? would it be If $Listbox = 0 Then ??
chssoccer Posted December 28, 2007 Author Posted December 28, 2007 How about _GUICtrlListBox_GetCount() ?Tried that, did:$Online = _GUICtrlListCount($ListBox)If $Online = 0 Then GUICtrlSetImage($nListview, "shell32.dll", -110)Else GUICtrlSetImage($nListview, "shell32.dll", -138)EndIf
GEOSoft Posted December 28, 2007 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 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.

chssoccer Posted December 28, 2007 Author Posted December 28, 2007 Try If $Online < 0 Then IIRC the function returns -1 when there are no items. That didn't work either...
therks Posted December 28, 2007 Posted December 28, 2007 What does this do? MsgBox(0, '', _GUICtrlListCount($ListBox)) My AutoIt Stuff | My Github
GaryFrost Posted December 28, 2007 Posted December 28, 2007 Is the listbox created by AutoIt or an external application? SciTE for AutoItDirections for Submitting Standard UDFs Don't argue with an idiot; people watching may not be able to tell the difference.
