Thanks Sergey,

You are really great!

I tried both of your solutions and both wroked fine! Still there is a small thing I have to ask. Both returned for the record number 20:
C74190B6-8589-11D1-B16A-00C0F0283628 and it really was the treeview CLSID
but for the record number 21 (imagelist) returned value was:
0000005C-0000-0000-0100-000000000000 this CLSID didn't exist in the registry.

Any Ideas?

Sincerely,

AT
