Helen,

are you aware, that some list member already ported the VirtualTreeview
into an IBVTree, which should run without too much modifications with
the latest VTree sources (Available in this lists file-area)? Rather
than trying to reprogram it, you could modify it and post an updated
version.I did never used it myself (although I use VTree Itself in
almost every app of mine), but afaik, it uses a TIB_Query, not TIBO, and
should be rather straightforward to use.

CU,
