Is Nothing? I wish...

I need to do a comparison to see if an object is nothing (I'm parsing through a tree and I want to see if the next sibling is nothing).  Is there anything like an IsNothing() compare? How can I check to see if an object=nothing.

Jeff, very good.  I don't understand why the designers of VB chose to go with such different method of dealing with invalid types.  There's "ISNULL" "ISEMPTY" and then simply IS for the Nothing object.  That's not very intuative.  Thanks.

P.S. You are right, ISNULL won't work for nothing objects.  I've tried.
