ListView Control $LVN_ITEMACTIVATE help

Recommended Posts


I am having issues trying to detect a doublelclick in a listview control. According to smashly, the issue is with an int in the $tagNMHDR struct not being converted to int64. I need assistance correcting this, whether in the struct or a workaround (other than running 32bit).

The following link is to the discussion, few months old now.


Some code that only notifies me with a msgbox when I run 32bit:

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

$Form1 = GUICreate('boo', 361, 270, 200, 200)

;~ Create listview
    $hListView = GUICtrlCreateListView( "", 0, 0, 260, 377) ; LEFT],[TOP],WIDTH],[HEIGHT]

  ; Add columns
    _GUICtrlListView_InsertColumn($hListView, 0, "Column 1", 100)
    _GUICtrlListView_InsertColumn($hListView, 1, "Column 2", 150)

    ; Add items
    _GUICtrlListView_AddItem($hListView, "Row 1: Col 1", 0)
    _GUICtrlListView_AddSubItem($hListView, 0, "Row 1: Col 2", 1)

    _GUICtrlListView_AddItem($hListView, "Row 2: Col 1", 1)
    _GUICtrlListView_AddSubItem($hListView, 1, "Row 2: Col 2", 1)


$msg = GUIGetMsg()
Until $msg = $GUI_EVENT_CLOSE

;~ ========================================================
;~ This thing is responsible for click events
;~ ========================================================
Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)

    Local $hWndFrom, $iCode, $tNMHDR, $hWndListView
    $hWndListView = $hListView
    If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView)

    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $hWndFrom
        Case $hWndListView
            Switch $iCode

                Case $LVN_ITEMACTIVATE  ; Sent by a list-view control when the user double-clicks an item with the left mouse button
                   Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)

                   $Index = DllStructGetData($tInfo, "Index")

                   $subitemNR = DllStructGetData($tInfo, "SubItem")

                   ; make sure user clicks on the listview & only the activate
                   If $Index <> -1 Then

                       ; col1 ITem index
                        $item = StringSplit(_GUICtrlListView_GetItemTextString($hListView, $Index),'|')
                        $item = $item[1]

                        ;Col item 2 index
                        $item2 = StringSplit(_GUICtrlListView_GetItemTextString($hListView, $subitemNR),'|')
                        $item2= $item2[2]

                        MsgBox(0,"",$item & ' ' & $item2 & @CRLF)


EndFunc   ;==>WM_NOTIFY

Are you sure you compiled it for 64-bit? Because the tag is $tagNMHDR = "hwnd hWndFrom;uint_ptr IDFrom;INT Code", and uint_ptr will be either 32-bit or 64-bit depending on how you compiled the script (see help file under DllStructCreate() for types).


Edit: Add #AutoIt3Wrapper_UseX64=Y to the top of your script.
