Problem selecting listview item to tick a checkbox

[laffo16]

Good evening guys

Struggling to find away to fix this problem. I basicly want to click an item in the listview, and it ticks the checkbox for me on the side. at the moment im using WM_Notify to activate the checkbox, but the problem is now if i tick the checkbox the command is sent twice (once via WM_notify and once by me manualy clicking, nulling the operation). i'm not sure if NW_notify is the correct way of doing this, not sure if ive missed an ex-style or something which may accomplish this more easily. heres the code.

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Array.au3>
#include <GuiListView.au3>

$search_gui = GUICreate("Product Scanner", 400, 300, -1, -1)
$listview = GUICtrlCreateListView("Product ID|Category|Last Update", 2, 2, 394, 250)
_GUICtrlListView_SetExtendedListViewStyle($listview, BitOR($LVS_EX_BORDERSELECT, $LVS_EX_FULLROWSELECT, $LVS_EX_CHECKBOXES, $LVS_EX_GRIDLINES))
GUISetState()

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

GUICtrlCreateListViewItem("1|2|3", $listview)
GUICtrlCreateListViewItem("4|5|6", $listview)
GUICtrlCreateListViewItem("7|8|9", $listview)

While 1
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd
GUIDelete()

Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg, $iwParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView, $tInfo
    $hWndListView = $listview
    If Not IsHWnd($listview) Then $hWndListView = GUICtrlGetHandle($listview)

    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    
    If $hWndFrom = $hWndListView And $iCode = $NM_CLICK Then
        $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
        If DllStructGetData($tInfo, "Index") >= 0 Then
            If _GUICtrlListView_GetItemChecked($listview, DllStructGetData($tInfo, "Index")) = 0 Then
                _GUICtrlListView_SetItemChecked($listview, DllStructGetData($tInfo, "Index"), 1)
            Else
                _GUICtrlListView_SetItemChecked($listview, DllStructGetData($tInfo, "Index"), 0)
            EndIf
        EndIf
    EndIf
EndFunc

appreciate any help with this, thanks

you need to hittest and check that the click is not on a checkbox

wow, some v nice code their rover, way over my head. much appreciate the help m8. ty

[laffo16]

sorry to bump old thread, have just upgrades to win7 (64bit) from xp and rovers example above has been broken, anyone know how to fix this? any help appreciated.

DllStructGetData($tInfo, "Index") is returning 0 regardless of row being clicked. perhaps a problem with

$tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)?
