ListView Control $LVN_ITEMACTIVATE help

[Psibernetic]

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:

expandcollapse popup

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


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

;~ Create listview
    $hListView = GUICtrlCreateListView( "", 0, 0, 260, 377) ; LEFT],[TOP],WIDTH],[HEIGHT]
                 _GUICtrlListView_SetExtendedListViewStyle ($hListView, BitOR($LVS_AUTOARRANGE,$LVS_EX_FULLROWSELECT,$LVS_EX_DOUBLEBUFFER,$LVS_EX_SUBITEMIMAGES,$LVS_EX_ONECLICKACTIVATE))

  ; 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)
