title: How to access elements from a CMap?
body: <p>Can someone please enlighten me about how to get a particular element based on a particular key. Say If i have a CMap ButtonProp; 
  and now i want to access the property for any int value supplied, how to do that? 
  P.S. First time with CMap. Does "ButtonProp.Lookup(int)" suffice?</p>
