Here's some code I use. Hopefully self explanatory:

// Set the horizontal scroll
int oldwidth = m_cListBox.GetHorizontalExtent();
CDC* pDC = m_cListBox.GetWindowDC();
if (pDC) {
      int newwidth = (int)(pDC->GetTextExtent(szMsg,
(int)_tcslen(szMsg)).cx);
      m_cListBox.ReleaseDC(pDC);
      if (newwidth > oldwidth)
           m_cListBox.SetHorizontalExtent(newwidth);
}

// Add the new one at the end
if(bFileMsg) {
      int nLast = m_cListBox.GetCount();
      if(nLast > 0)
           m_cListBox.DeleteString(nLast-1);
}

m_cListBox.AddString(szMsg);

if(m_bAutoScrollStatus) {
      // Keep the last one in view
      m_cListBox.SetTopIndex(m_cListBox.GetCount()-1);
}

Hello NG,

I have a normal CListBox in my dialog. I insert text with AddString. The
string is longer than the area to show the listbox. But I cannot
horizontal
scroll the text.
I changed the properties: horizontal scrollbar = true, vertical scrollbar
=
true, deactivate no scrolling = true.
But I cannot horizontal scroll.

I use MSVC Developer 2003, Version 7.1.3088 and Windows XP.

Can you help me?
Thanks,
Guido
