GUIRegMsg function working twice

17 posts in this topic

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

    $hWndFrom = HWnd(DllStructGetData($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)

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

      Hi
      Best example I could find is here
      ::/html/libfunctions/_GUICtrlTreeView_ClickItem.htm
      The way I understand this, the standard Windows messages, such as Left/Right Click etc are covered by AutoIt macros, but the real power is locked up inside this WM_NOTIFY .  I have tried, but I am not even sure I understand what I am looking at.
      I need help understanding this.  What I am looking for is Help file or Tutorial explaining how this works?  
      Perhaps if there is a script showing both the working of an AutoIt macro and the WM_NOTIFY  in action, it would help.
      Right now I am so lost, I do not even know what are the right questions to ask.  One issue I have is on ListViews, how to combine the "Click" of a line with a standard Switch loop?  Like users clicks a line, then get the loop to detect the click and ;do something ...
      Any ideas?

      Hey guys,
      After much searching and reading I Siao's example script from the below link is the closest to what I need to do.
      I have a ListView that is populated with the names of different configurations.  When a Listview item is selected, a form is populated with that items data.  Right now I have a column that shows which item's data is shown in the form, but it would be much cleaner to just have the current item highlighted.
      My problem is this - The highlighting in Siao's example works great, but inside the Listview when you select in the "empty" space to essentially deselect everything the highlighting disappears.
      How can I keep the last selected item highlighted when clicking in this empty space?
      Also - I do not understand enough about Windows notifications to understand if we could utilize SendMessage to initiate a custom draw....  It seems to me that you could specify an item and then invoke the DLL function to redraw the item that you specified with the colors that you specified.... That's the idea I get when I read the MSDN documentation on it: https://msdn.microsoft.com/en-us/library/windows/desktop/ff919573(v=vs.85).aspx
       
      Siao's Example modified for latest AutoIt:

      I have a script that writes a message to the console whenever a WM_NOTIFY event is detected. but I don't get the events.
      Here is my test script:

      Issue: If either date picker controls receive focus, then use arrow keys to change date in edit portion, flags do not set to True until mouse move or mouse click.
      I have used this exact method in the past & it works perfectly. I just can't figure out what I am doing wrong here. The only thing different I can think of is I just updated my Autoit version to ;Autoit v3.3.14.0 & if it matters system I am using is running Win7 Pro x86.
