SetScrollSizes is for setting the limits of the scrollbar, if you did that
it would mess up the scrolling process.

If SB_LINEDOWN is too slow then pass SB_PAGEDOWN or SB_THUMBPOSITION to
OnVScroll.

BOOL CMyFormView::PreTranslateMessage(MSG* pMsg)
{
    if (pMsg->message == WM_KEYDOWN)
    {
       if (pMsg->wParam == VK_DOWN)
       {
          ScrollInfo Info;
          GetScrollInfo(SB_VERT,&Info);
          OnVScroll(SB_THUMBPOSITION,Info.nPos+25,NULL);
       }
    }

    return CFormView::PreTranslateMessage(pMsg);
}

How about this?

BOOL CMyFormView::PreTranslateMessage(MSG* pMsg)
{
   if (pMsg->message == WM_KEYDOWN)
   {
      if (pMsg->wParam == VK_DOWN)
      {
         OnVScroll(SB_LINEDOWN,0,NULL);
      }
   }

   return CFormView::PreTranslateMessage(pMsg);
}

Hi,

I would like to know how I could scroll a CFormView with some scrollbars
by using arrow keys.
When using spy it seems scrollbar is directly managed by the view so I
don't know how to move it.

And if I found that SB_LINEDOWN scrolling is too slow, should I use
SetScrollSizes ?
