Hi Forum!

In this example, it work with _GUICtrlRichtEdit, how to implemente a character's total counter when is typing?

I try with GUIRegisterMsg($WM_NOTIFY, 'WM_NOTIFY') without success.

Thank you.

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

Example()

Func Example()
    Local $hGui, $hRichEdit, $iMsg
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, 4) & ")", 320, 350, -1, -1)
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
            BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    _GUICtrlRichEdit_AppendText($hRichEdit, @CRLF & "This is more text")
    GUISetState(@SW_SHOW)

    While True
        $iMsg = GUIGetMsg()
        Select
            Case $iMsg = $GUI_EVENT_CLOSE
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                ; GUIDelete()   ; is OK too
                Exit
        EndSelect

It's not WM_NOTIFY but WM_COMMAND with EN_UPDATE or EN_CHANGE message IIRC.

Detefon,

How about this: :)

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

Global $hRichEdit, $cLabel

Example()

Func Example()
    Local $hGui, $iMsg
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, 4) & ")", 320, 350, -1, -1)
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
            BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    ConsoleWrite($hRichEdit & @CRLF)
    $cLabel = GUICtrlCreateLabel("", 10, 250, 200, 20)
    GUICtrlSetData($cLabel, _GUICtrlRichEdit_GetTextLength($hRichEdit, True, True))
    GUISetState(@SW_SHOW)

    ; Tell RichEdit to send EN_CHANGE messages <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    _SendMessage($hRichEdit, $EM_SETEVENTMASK, 0, $ENM_CHANGE)

    GUIRegisterMsg($WM_COMMAND, "_WM_COMMAND")

    $nBegin = TimerInit()

    While True
        $iMsg = GUIGetMsg()
        Select
            Case $iMsg = $GUI_EVENT_CLOSE
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                ; GUIDelete()   ; is OK too
                Exit
        EndSelect

        If TimerDiff($nBegin) > 1000 Then
            _GUICtrlRichEdit_AppendText($hRichEdit, @CRLF & "This is more text")
            $nBegin = TimerInit()
        EndIf

    WEnd
EndFunc   ;==>Example

Func _WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
    Local $iCode = BitShift($wParam, 16) ;HiWord
    If $lParam = $hRichEdit And $iCode = $EN_CHANGE Then
        GUICtrlSetData($cLabel, _GUICtrlRichEdit_GetTextLength($hRichEdit, True, True))
    EndIf
EndFunc   ;==>_WM_COMMAND
Please ask if you have any questions. :)

Melba,

No need of _SendMessage if as Firefox suggested $EN_UPDATE is used in the _WM_COMMAND func

mikell,

 

No need of _SendMessage

Have you tried running the code without that line? :huh:

You might want to read the Remarks on this MSDN page. ;)

Detefon,

 

It is important or irrelevant?

_WM_COMMAND and WM_COMMAND are the same commands/functions?

Completely irrelevant - you could name the handler function "Fred" if you so desired. What is important is the message you are registering ($WM_COMMAND) as otherwise you will not intercept the Windows message stream and the code will not work. ;)
