Hi all,
I am trying to get the selected item text from a tree view control.
For that i am using this code. Please take a look. In this code, i am using console write function so that i am able to know that the user clicks in an item. This code works perfectly at the first click. But when i click on an item second time, it will work twice, That means, console write will work twice. Same result is at the third and fourth click also. 
 

Func TreeView_WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndTreeview
    $hWndTreeview =  $tv1
    If Not IsHWnd($tv1) Then $hWndTreeview = GUICtrlGetHandle($tv1)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $hWndFrom
        Case $hWndTreeview
            Switch $iCode
                Case $TVN_SELCHANGINGW                  
                    ConsoleWrite("Clicked" & @CRLF)
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

You should know better by now, post a script that shows the problem, not a snippet that someone has to build the script around. No way we'll be able to recreate your exact script, so there's no way we'll know where the issue is.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I don't know well about treeviews but this seems to work

Func TreeView_WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndTreeview
    $hWndTreeview =  $tv1
    If Not IsHWnd($tv1) Then $hWndTreeview = GUICtrlGetHandle($tv1)
    Static $hItem0

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Local $cntr = 0
    Switch $hWndFrom
        Case $hWndTreeview
            Switch $iCode
                Case $TVN_SELCHANGEDW
                    ; Insert your code here
                    $hItem = _GUICtrlTreeView_GetSelection ($hWndTreeview)
                    If $hItem <> $hItem0 Then
                        ConsoleWrite("Clicked " & _GUICtrlTreeView_GetText($hWndTreeview, $hItem) & @CRLF)
                        $hItem = $hItem0
                    EndIf
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

Edit
There is probably certainly an easier way   :huh:

Thanks @mikell . I would like to know what is that easier way.

It's probably a Windows related issue and probably has nothing to do with AutoIt.

@BrewManNH So you mean that the code is alright. ?

Edit - @BrewManNH No. That's not right. I have tested it in my laptop(win 8.1 64 bit) and my pc (win 8 32bit). Both gave same result.

I was referring to the original proposition that the message handler is getting called twice on a single click. I'd guess that's a Windows issue and isn't an AutoIt one, and workarounds are the only thing you can do to get them to work the way you want them to.

kcvinu,
What about this ?

Func TreeView_WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndTreeview
    $hWndTreeview =  $tv1
    If Not IsHWnd($tv1) Then $hWndTreeview = GUICtrlGetHandle($tv1)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Local $cntr = 0
    Switch $hWndFrom
        Case $hWndTreeview
            Switch $iCode
            Case $TVN_SELCHANGEDW
                $txt = GuiCtrlRead($tv1, 1)
                If $txt <> "" Then ConsoleWrite("Clicked " & $txt & @CRLF)
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

@mikell Same result. Nothing happens at the first click. Then everything is ok

Hoho, it seems that putting "Return 0" instead of "Return $GUI_RUNDEFMSG" is solving the 'working twice' problem in the previous codes  :)

This:

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

    ;wparam = cid, lparam = pnmh
    If $wParam = $cTree Then

        Local $code = DllStructGetData($tNMHDR, "code")
        Local $hTree = HWnd(DllStructGetData($tNMHDR, "hTree"))
        Switch $code
            Case $TVN_BEGINLABELEDITA, $TVN_BEGINLABELEDITW

                _SendMessage($hTree, $TVM_GETEDITCONTROL, 0, 0)

works for me.

@Danyfirex Your code is working perfect in my function. Thanks. 

@AutoBert I will check your code later and will inform you the result. Thanks.
