Answer: If you've tried setting your tables as hidden objects and the users are still able to find them, you can always set your tables up as system tables. Inside of your Access database, there are several system tables that even you can't see. These tables are used internally by the Access database.

Bind combo box to primary key but display a description field in Access

Question: In Access 2003/XP/2000/97, I've set up a table that contains an autonumber field as the primary key and a description field. I want to be able to create a combo box that displays the description, but stores the primary key. How do I set up the combo box?
Answer: Quite often the primary key value can mean nothing to the user. Instead, there is a description field in the table that relays the meaning of the record. In Access you can link a combo box to the primary key, but display the description in the combo box itself.
To do this, first create a combo box object. Right-click on the combo box and select Properties from the popup menu.

interval is the interval of time to use to calculate the difference between date1 and date2. Below is a list of valid interval values.
