name15,

When you post here it always helps if you have had a go at solving your problems beforehand. Having some code to work on is a great help - and no-one here is too keen to help the "code it for me" brigade. :)

To do what you want, you need to trap the NM_DBLCLK message from the TreeView. Why not try yourself - there are lots of examples on the forums if you search.

If you get stuck...... ;)

#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

name15,

So post your code so we can see what might be wrong - my crystal ball is not working very well today. :)

Does anyone know why this code no longer works on Windows 7 x64?

The struct is bad.

Change

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

to

Local $tStruct = DllStructCreate($tagNMHDR, $lParam)
If @error Then Return
If DllStructGetData($tStruct, 3) = $NM_DBLCLK Then $fDblClk = True
EndSwitch
