List of elements of isolated objects in VB Script

[RGenin]

Hello, 

How could I replicate the "Find isolated objects" list (Right-Click on Environnement menu) in VB Script ?

 Find isolated objects

In VB, I usually have to specify the type of objects for querying with a GetCollection or GetSelection, but I don't know how to do that for every type of objects.

Thanks a lot, 
Raphaël.
