Stop double click from copying label contents to clipboard?

[therks]

I'm not sure when this started happening but it's very annoying and it took me a while to realize it wasn't a bug in my code. Is there some way to keep this from happening? Is it a bug or a feature? I checked on a few other Static controls in Windows and it doesn't copy on double click so I can only think it's AutoIt exclusive.

AutoIt:3.3.9.5 (Os:WIN_7/SP1/X64 OSLang:0409)

Example:

#include <GUIConstants.au3>

$hGUI = GUICreate('', 150, 100)
GUICtrlCreateLabel('Double click me', 5, 5, 100, 20)
GUISetState()

ClipPut('Example')

While 1
    ToolTip('ClipGet() = ' & ClipGet())
    $iGUIGetMsg = GUIGetMsg()
    Switch $iGUIGetMsg
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
WEnd

Damn, 2 weeks and nothing?

It's a feature of Static controls. If you don't want it then remove SS_NOTIFY style.

[PhoenixXL]

The reason of this problem is that the Label receives the WM_GETTEXT message when we double click on it. To stop this behavior, we can ignore the WM_GETTEXT message when double-clicking operation happens.

To do this, create a new class derived from the Label class and override the WndProc method. In the override method, if the Label has received the WM_LBUTTONDBLCLK message before it receives the WM_GETTEXT message, we ignore the WM_GETTEXT message.

The following is a sample:

class MyLabel:Label

{

int WM_GETTEXT = 0xD;

int WM_LBUTTONDBLCLK = 0x203;

bool doubleclickflag = false;

protected override void WndProc(ref Message m)

{

if (m.Msg == WM_LBUTTONDBLCLK)

{

doubleclickflag = true;

}

if (m.Msg == WM_GETTEXT && doubleclickflag)

{

doubleclickflag = false;

return;

}

base.WndProc(ref m);

}

}The reason of this problem is that the Label receives the WM_GETTEXT message when we double click on it. To stop this behavior, we can ignore the WM_GETTEXT message when double-clicking operation happens.

But how to use this class through Autoit [i dont have any idea]

I got this from this Link

Its not just for Autoit, its for all the Static controls in Windows Vista and above

try Subclassing

orelse try tracking the doubleclick event and restore the Clipboard

[PhoenixXL]

i tried to remove the SS_NOTIFY but it didnt work

This will work

Create the label with $SS_SIMPLE

& Disable the Label

This will stop receive you messages from the label and the text wont be copied

Code

#include-once
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
$hGUI = GUICreate('', 150, 100)
GUICtrlCreateLabel('Double click me', 5, 5, 100, 20,0x0B)
GUICtrlSetState(-1,$GUI_DISABLE)
GUISetState()

ClipPut('Example')

While 1
ToolTip('ClipGet() = ' & ClipGet())
$iGUIGetMsg = GUIGetMsg()
Switch $iGUIGetMsg
Case $GUI_EVENT_CLOSE
ExitLoop
Case Else
If $iGUIGetMsg > 0 Then
ToolTip($iGUIGetMsg &amp; ':' &amp; GUICtrlRead($iGUIGetMsg))
EndIf
EndSwitch
WEnd

PhoenixXL,

Removing the SS_NOTIFY style is just one line:

#include <GUIConstants.au3>

$hGUI = GUICreate('', 150, 100)
GUICtrlCreateLabel('Double click me', 5, 5, 100, 20)
GUICtrlSetStyle(-1, 0) ; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
GUISetState()

ClipPut('Example')

While 1
    ToolTip('ClipGet() = ' & ClipGet())
    $iGUIGetMsg = GUIGetMsg()
    Switch $iGUIGetMsg
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case Else
            If $iGUIGetMsg > 0 Then
                ToolTip($iGUIGetMsg & ':' & GUICtrlRead($iGUIGetMsg))
            EndIf
    EndSwitch
WEnd

Your subclassing idea is interesting but I am not sure that it is entirely correct. When I subclass the label as you propose I certainly do not get the content of the label on a double click, but the clipboard content is still erased:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <WinAPI.au3>

OnAutoItExitRegister("_AutoExit")

Global $fDblClk = False

; Register callback function and obtain handle to _New_WndProc
$hNew_WndProc = DllCallbackRegister("_New_WndProc", "int", "hwnd;uint;wparam;lparam")

; Get pointer to _New_WndProc
Local $pNew_WndProc = DllCallbackGetPtr($hNew_WndProc)


$hGUI = GUICreate('', 150, 100)
$clabel = GUICtrlCreateLabel('Double click me', 5, 5, 100, 20)
GUISetState()

; Store old WndProc
$pOld_WndProc = _Label_SubClass(GUICtrlGetHandle($cLabel), $pNew_WndProc)


ClipPut('Example')

While 1
    ToolTip('ClipGet() = ' & ClipGet())
    $iGUIGetMsg = GUIGetMsg()
    Switch $iGUIGetMsg
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case Else
            If $iGUIGetMsg > 0 Then
                ToolTip($iGUIGetMsg & ':' & GUICtrlRead($iGUIGetMsg))
            EndIf
    EndSwitch
WEnd


Func _New_WndProc($hWnd, $iMsg, $wParam, $lParam)

    ; Set DBLCLK flag if one detected
    If $iMsg = 0x203 Then
        $fDblClk = True
    EndIf

    ; If GETTEXT message sent
    If $iMsg = 0x000D Then ; WM_GETTEXT
        ; Check state of DBLCLK flag
        If $fDblClk Then
            ; Clear flag
            $fDblClk = False
            ; Ignore specific message from subclassed control
            Return 0
        Else
            ; Pass message to original WindowProc
            Return _WinAPI_CallWindowProc($pOld_WndProc, $hWnd, $iMsg, $wParam, $lParam)
        EndIf
    Else
        ; Pass other messages to original WindowProc
        Return _WinAPI_CallWindowProc($pOld_WndProc, $hWnd, $iMsg, $wParam, $lParam)
    EndIf

EndFunc   ;==>_New_WndProc

Func _Label_SubClass($hWnd, $pNew_WindowProc)

    Local $iRes = _WinAPI_SetWindowLong($hWnd, -4, $pNew_WindowProc)
    If @error Then Return SetError(1, 0, 0)
    If $iRes = 0 Then Return SetError(1, 0, 0)
    Return $iRes

EndFunc   ;==>_Label_SubClass

Func _AutoExit()

    ; Unsubclass the label
    _Label_SubClass(GUICtrlGetHandle($cLabel), $pOld_WndProc)
    ; Now free UDF created WndProc
    DllCallbackFree($hNew_WndProc)

EndFunc

So I think there is something else going on with the clipboard.

Anyway, trancexx's solution works fine - and is a lot simpler!

Edit:

In fact all you need to do is to prevent the DBLCLK message being actioned:

Func _New_WndProc($hWnd, $iMsg, $wParam, $lParam)

    If $iMsg = 0x203 Then
        Return 0
    EndIf

EndFunc   ;==>_New_WndProc

But I would still just remove the SS_NOTIFY style.

Added code

[PhoenixXL]

Yup

removing SS_NOTIFY works that way

but this is even the same thing i guess then why isnt this working

#include <GUIConstants.au3>

$hGUI = GUICreate('', 150, 100)
GUICtrlCreateLabel('Double click me', 5, 5, 100, 20,0)
;GUICtrlSetStyle(-1, 0) ; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
GUISetState()

ClipPut('Example')

While 1
ToolTip('ClipGet() = ' & ClipGet())
$iGUIGetMsg = GUIGetMsg()
Switch $iGUIGetMsg
Case $GUI_EVENT_CLOSE
ExitLoop
Case Else
If $iGUIGetMsg > 0 Then
ToolTip($iGUIGetMsg & ':' & GUICtrlRead($iGUIGetMsg))
EndIf
EndSwitch
WEnd

and BTW does the following work

#include-once
#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
$hGUI = GUICreate('', 150, 100)
GUICtrlCreateLabel('Double click me', 5, 5, 100, 20,0x0B)
GUICtrlSetState(-1,$GUI_DISABLE)
GUISetState()

ClipPut('Example')

While 1
ToolTip('ClipGet() = ' & ClipGet())
$iGUIGetMsg = GUIGetMsg()
Switch $iGUIGetMsg
Case $GUI_EVENT_CLOSE
ExitLoop
Case Else
If $iGUIGetMsg > 0 Then
ToolTip($iGUIGetMsg & ':' &GUICtrlRead($iGUIGetMsg))
EndIf
EndSwitch
WEnd

Unfortunately I can't just disable double clicking entirely in my program because I'm actually using the double click to trigger something. I just don't want it to affect the clipboard.

*Edit: I actually thought that copying label contents to clipboard on double click was something that happened only recently, and I was thinking it was almost bug-like, but I just found an old compiled script (3.1.1.61) and labels in it do the same thing, so I guess I just over looked it all this time.

*Edit 2: Although I just tested on a WinXP VM and it doesn't copy, so maybe that's where I'm getting mixed up (I haven't done nearly as much scripting since I moved to Win 7).

Stop double click from copying label contents to clipboard?

CS_DBLCLKS style issue again.

My solution for the static/button click lag/slowdown issue a few years back solves this one too.

expandcollapse popup

#include <GUIConstants.au3>
#include <WinAPIEx.au3>

$hGUI = GUICreate('', 150, 100)
$cLbl = GUICtrlCreateLabel('Double click me', 5, 5, 100, 20)
_Remove_CS_DBLCLKS(-1)
GUISetState()

ClipPut('Example')

While 1
ToolTip('ClipGet() = ' & ClipGet())
$iGUIGetMsg = GUIGetMsg()
Switch $iGUIGetMsg
     Case $GUI_EVENT_CLOSE
         ExitLoop
;Case $cLbl
;ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $cLbl = ' & $cLbl & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
     Case Else
         If $iGUIGetMsg > 0 Then
             ToolTip($iGUIGetMsg & ':' & GUICtrlRead($iGUIGetMsg))
         EndIf
EndSwitch
WEnd
