    Scrolling a multiline Edit(box) automatically (Win32)

    I'd like to scroll to the bottom of an Edit automatically whenever a line is added, so I wrote this:


    SendMessage(hWnd(), LOWORD(WM_VSCROLL), SB_BOTTOM, 0);




    hWnd() returns the hwnd of the edit.

    This worked just fine under Win2k but it doesn't work at all under Win98. What am I doing wrong?

    Try writing something like this:

    Code:
    //////////////// My Edit Box Control settings: ////////////////////
    EDITTEXT        IDC_EDIT1,12,88,396,98,ES_MULTILINE | ES_AUTOVSCROLL | WS_VSCROLL
    CString	m_EditBoxValue;
    DDX_Text(pDX, IDC_EDIT1, m_EditBoxValue);
    //////////////////////////////////////////////////////////////////////////
    
    CEdit * eb;
    eb = (CEdit*)GetDlgItem(IDC_EDIT1); // Set V
    
    //this is an example
    
    for (int i = 0; i < 1000; i++)
    {
    
       m_EditBoxValue += "New Text ABCDEFGHIJKLMNOPQRSTUVWXYZ Tralalalalalalalalal";
    
       UpdateData(FALSE); 
    
       eb->LineScroll(eb->GetLineCount());
    Hope, someone finds it useful.

    "Hope, someone finds it useful."

    I do not expect some people to understand what they read and why I have posted that replay. Some are just too narrow minded i.e. lack of imagination Have a nice day "Einstein".

    Sorry, I really didn't understand how important is to solve Win98 problems... It is not enough that program runs successfully in Win2K - we should not forget about Win98/95 users.

    The question is: was this solution even tested on Win98?
