Hierarchical Drop Down Combo without Activex
Recently while I was working on a new application and trying to find an efficient way for selecting an option from a ComboBox I remembered the article of Predrag Bosnic in the FoxTalk magazine (December 2002 - you are a subscriber, Isn't it?) that explains the making of a combined ComboBox control with a Treeview ActiveX. For some (mysterious) reasons, I dislike activeX controls. Instead of them, I prefer to build or use only pure VFP controls. So I decided to make one on my own.
Definitely, my control has serious limitations over Predrag's ComboTree view control (images, deep nesting level,drag n drop, etc...) but for now I can live with it.
My scope is to make it public in order to improve it. The control has code / ideas from Megafox book (Andy Kramek, Marcia Akins, Rick Schummer), Craig Boyd, Predrag Bosnic, Art Bergquist and I would like to say a big THANK you to all of them. Also, I would like to thank Tasos Bazotis and Fay Bazoti for their contribution.

P.S : Please show mercy, as it is my first try to make public some code bits.
