// OnClick in the handler for the NM_CLICK notification
void CMyListCtrl::OnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
   // Get the current mouse location and convert it to client
   // coordinates.
   DWORD pos = GetMessagePos();
   CPoint pt(LOWORD(pos), HIWORD(pos));
   ScreenToClient(&pt);

   // Get indexes of the first and last visible items in 
   // the listview control.
   int index = GetTopIndex();
   int last_visible_index = index + GetCountPerPage();
   if (last_visible_index > GetItemCount())
       last_visible_index = GetItemCount();

   // Loop until number visible items has been reached.
   while (index <= last_visible_index)
   {
       // Get the bounding rectangle of an item. If the mouse
       // location is within the bounding rectangle of the item,
       // you know you have found the item that was being clicked.
       CRect r;
       GetItemRect(index, &r, LVIR_BOUNDS);
       if (r.PtInRect(pt))
           {
               UINT flag = LVIS_SELECTED | LVIS_FOCUSED;
               SetItemState(index, flag, flag);
               break;
          }

       // Get the next item in listview control.
       index++;
   }

   *pResult = 0;
