title: CListCtrl - how to find it is selected
body: <p>I have got a CDialog Class, inside which there are two ClistCtrl classes.
  I want to find out which of the listCtrl's is selected at the moment.
  say, listCtrl A and B. Even when I move between A and B, suppose first I go to A and select a row. Then even when I go to B and select an item there, item in A remains selected as I don't come to know that I have gone in other list.</p>
  
  <p>Any suggestions, how I can find this.</p>
