int index = m_myListCtrl.GetTopIndex();
int last_visible_index = index + m_myListCtrl.GetCountPerPage();
if (last_visible_index > m_myListCtrl.GetItemCount())
last_visible_index = m_myListCtrl.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;
m_myListCtrl.GetItemRect(index, &r, LVIR_BOUNDS);
if (r.PtInRect(pia->ptAction))
