Why do HIDDEN OBJECTS not show in the Navigation Pane when the Navigation Option is set to Show Hidden Objects?

Hi Experts,

Summary: Does anyone know why, when I make a table a hidden object using VBA code, and then turn on Show Hidden Objects from Navigation objects, the table don't show back up?

Situation:
I'm creating tighter security for a client's sensitive data with an MS Access front end and back end. The back end is password protected, which I know there are a lot of very easy to use utilities on the web where you can use to find out the Database password.  So I'm taking further steps to secure. One of them will be will be to remove the Navigation Pane, turn off the By Pass Key (with a secret way to turn it on) and use a custom ribbon that prevent a user from opening up Options. All that said, if a user can find the password for the database, they can Import or Link to the back end tables, UNLESS they are hidden. So I've written code to hide all the tables in the back end which is launched from an outside application.

tblDef.Attributes = dbHiddenObject

Select all Open in new window

All this works fine. My question is... when hide tables in this manner, and I by pass the start up (using my secret way), and then go into File / Options and turn on Show Hidden Objects
in the Navigation Options, the hidden tables DO NOT SHOW. Does anyone know why?

I've added some code to turn the the hidden object off from the outside app, and when I do that, the tables reappear.

Any help on this would be greatly appreciated.

Thanks,
Eddie
