I want to use a linked list, stack, tree, etc in a VB based product. I am
sure someone has already done this job of writing standard COM libraries
for these datastructures. Can you point me to one such library? Is any free
library available too?

What do you call a Tree which can have more than two branches and is not
ordered in any particular fashion (like the one that stores the file strucute
on a drive)? It's not a binary tree.. is there a particular name for it?

Thanks in advance.
