ActiveX dll with a Treap class. A Treap is a high performance alternative to Collection and Dictionary. You can also compile it directly into your code and get rid of the sccrun.dll dependency.
Very good implementation for use in VB. Source code has an error with the Value iterator. E-mail to author bounces - hopefully he will get in touch if he reads this!
