_GUICtrlEdit_AppendText with rollover

Recommended Posts


As you know _GUICtrlEdit_AppendText is limited to the length of the Edit control.
For my need, I modifiied _GUICtrlEdit_AppendText to allow rollover and keep adding news lines removing previous ones.
I am using it to display logging traces of a running program.

Hope it helps some of us

Func _GUICtrlEdit_AppendText_Rollover($hWnd, $sText)
    If Not IsHWnd($hWnd) Then $hWnd = GUICtrlGetHandle($hWnd)

    Local $iLength = _GUICtrlEdit_GetTextLen($hWnd)
    Local $iLengthStr = StringLen($sText)

    if $iLength + $iLengthStr > _GUICtrlEdit_GetLimitText ($hwnd) Then
        ;remove a piece of edit
        _GUICtrlEdit_SetSel($hWnd, 0, $iLengthStr)
        _GUICtrlEdit_ReplaceSel ( $hWnd, "",False)
    _GUICtrlEdit_SetSel($hWnd, $iLength, $iLength)
    _SendMessage($hWnd, $EM_REPLACESEL, True, $sText, 0, "wparam", "wstr")

EndFunc   ;==>_GUICtrlEdit_AppendText_Rollover
