What I'm trying to achieve is a single, quick test that will compare 2 sets of states and give the following results:

State1 State2 Result
 T       T      T
 T       F      F
 F       T      T
 F       F      T

The first state indicated if something if being used and the second if access is granted. I really want to do this check when creating nodes for a treeview so speed is quite important.

Can anyone point me to a solution?
Thanks in anticipation.
