SceneGraph

Hi all!
I was trying to write a script to display a scenegraph editor from which it is possible to edit hiearchy of the scene, edit simple properties for object in the scene (such as name, color, see-through, etc) and (if possible) implement functionalities such as drag and drop of objects in the tree list.
I was using the "scene tree list" example from the 3DStudioMax 8 Script Reference guide, which uses an ActiveX control to generate the tree-list.

Is it possible to modify that example to implement the functionalities I wrote above plus make it auto-refreshing when editing the scene??

Thanks in advance!
Regards,
Adriano
