No, actually I was just trying to access a node's index in the TreeNodeCollection in order to be able to insert another node before or after it in the collection. I just noticed the somewhat incomprehensible code in the Managed C++ section of the MSDN help for that method while I was browsing around.
Please don't bother me... I'm hacking code right now. Doesn't anybody remember what "hacking" really means? :sigh:
