Thanks for your reply.
So, sometimes ago I got a form with a treeview, this one was attched with a table.
This table contain the querys, I mean when the user make click on a node thisone find the code in the table and check if the user has permission to do the option, and others thing, but my hard disc had problem and I get lost almost all the informaction and my backup files isn´t this file.
Well, I lament that honestly.... :-(
