AutoIt3_x64.exe - GUIRegisterMsg($WM_NOTIFY, "MY_WM_NOTIFY")

[mlipok]

AutoIt:3.3.4.0/X64 (Os:WIN_7/X64 Language:0415 Keyboard:00000415 Cpu:X64)

I check example on this site

​http://www.autoitscript.com/forum/index.php?showtopic=105728&st=0&p=747136&hl=MY_WM_NOTIFY&fromsearch=1&#entry747136

works very well on
"c:\Program Files (x86)\AutoIt3\AutoIt3.exe"

but had problem on
"c:\Program Files (x86)\AutoIt3\AutoIt3_x64.exe"

here is this scripts

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

Global $aData[5] = [4, "Item 1", "Item 2", "Item 3", "Item 4"]
Global $aItem_Handles[UBound($aData)]

Global $hMain_GUI = GUICreate("TreeView Demo", 500, 500)

$hTree = GUICtrlCreateTreeView(10, 10, 480, 480)
$hRoot = GUICtrlCreateTreeViewItem("Root", $hTree)
For $i = 1 To $aData[0]
    $aItem_Handles[$i] = GUICtrlGetHandle(GUICtrlCreateTreeViewItem($aData[$i], $hRoot))
Next

GUISetState()

; Initialise "DoubleClick on TreeView function"
GUIRegisterMsg($WM_NOTIFY, "MY_WM_NOTIFY")

Global $fDblClk = False

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

    ; Check if tree view double clicked
    If $fDblClk = True Then
        $sText = _GUICtrlTreeView_GetText($hTree, _GUICtrlTreeView_GetSelection($hTree))
        MsgBox(0, "Hit", "You double clicked on " & $sText )
        $fDblClk = False
    EndIf
WEnd

Func MY_WM_NOTIFY($hWnd, $Msg, $wParam, $lParam)

    Switch $wParam
        Case $hTree
            Local $tagNMHDR = DllStructCreate("int;int;int", $lParam)
            If @error Then Return
            If DllStructGetData($tagNMHDR, 3) = $NM_DBLCLK Then $fDblClk = True
    EndSwitch
    $tagNMHDR = 0

EndFunc  ;==>MY_WM_NOTIFY

Your NMHDR structure declaration is not correct. Use AutoIt's $tagNMHDR to get a correct version. It appears the documentation is wrong for that structure but the structure itself is declared correctly. Your attempt to declare the structure is fine for x86 but is a full 8-bytes too small for x64.
