Re: last added line always visible in listbox

This is a code snippet, but this is a way I use listboxes to do status. I
always have a check box to stop it from autoscrolling but you could do
something like if the focus is not on the bottom line it would stop (this is
how VS works while compiling for example). This one also turns on the
horizontal scroll bar if some text gets too wide ...

void CMyDlg::AddStatusMessage(LPCTSTR szMsg)
{
    // Set the horizontal scroll
    int oldwidth = m_cStatus.GetHorizontalExtent();
    CDC* pDC = m_cStatus.GetWindowDC();
    if (pDC) {
        int newwidth = (int)(pDC->GetTextExtent(szMsg,
(int)_tcslen(szMsg)).cx);
        m_cStatus.ReleaseDC(pDC);
        if (newwidth > oldwidth)
            m_cStatus.SetHorizontalExtent(newwidth);
    }
    // Add the new one at the end
    m_cStatus.AddString(szMsg);
    if(m_bAutoScrollStatus) {
        // Keep the last one in view
        m_cStatus.SetTopIndex(m_cStatus.GetCount()-1);
    }
}
