There is no accurate method
to estimate the number of TableIDs the Access database engine uses during the
process of compiling a database as an MDE.  However, each VBA module and
each form uses one TableID, as a result, if the database has 500 forms, and
each form's HasModule property is set to Yes, as
many as 1,000 TableIDs are used.
