ListView Help

[jezzzzy]

The below code updates an input field to show how many listviewitems are selected. The problem is that the $GUI_EVENT_PRIMARYUP doesn't fire when clicking on a listviewitem - only on part of the listview itself (scrollbar, emptyspace, column header, etc). I have searched the forums and there are lots of people who aparently have something similar to this working. Not sure what the problem is.

$listView= GUICtrlCreateListView("Email Lists",120+$halignInput,190+$valignInput,220,115,BitOR($LVS_REPORT, $LVS_SORTASCENDING,$LVS_NOCOLUMNHEADER))

;Then a function that adds listview items based on folder contents
;Other stuff
;Then my msg loop

        Case $msg = $GUI_EVENT_PRIMARYUP
            $pos = GUIGetCursorInfo()
            If ($pos[4] = $listView) Then
                GUICtrlSetData($inputField,_GUICtrlListViewGetSelectedCount($listView))
            EndIf

Yep, I have the same problem.

Would like to know a solution too.

Anyone ?

why not use a click event instead of trying to get primary up?

expandcollapse popup
