I do have a database named bom(bill of materials database).dbc

This database and application resides on winnt server.
And clients map their systems to some drive(temporary) and start their applications which connects to bom.dbc.

But my users are very smart. On their local machines they do have foxpro or visual foxpro, through which they access that database through visual foxpro and start their own manipulation in tables.

I want to make this database secured in such a way that they cant see the contents they cant do anything, but they can do read and write operations once they login into application.

I think you understand the situation, if any problems i will explain again.

Regards,
Sunil
