Is it possible to make a module invisible through code.

The SQL-database has a table 'Relation' with a field 'Type'. With the field 'Type' a relation can be defined as manager or employee. The table 'Relation' has a field 'DNN_User' too which gives the user name of the DNN-user. With a SELECT-statement I can see if a user is a manager or an employee.

When a manager logs in at the DNN website I want to show more modules (Text/HTML, Media, etc.) than when an employee logs in. So, I want to make some modules invisible when an employee logs in.

Is this possible?

Thanks in advance.

I know seperate paged can be made to show on each type of relation.
Both pages are almost the same with several modules. 1 or 2 modules are different.

Because I don't want to maintain the same modules on both pages I would like to make the different module invisible when an employee is logged in.

That's the idea.

The permission for a module can be set for administrators, all users, registered users, subscribers and Unauthenticated Users.
Both of my users (managers and employees) are registered users. How can I make a difference between them.

So, all modules on the page have permissions for registered users at this moment. I think I need an extra permission for visibility of 1 or 2 modules for the managers.

May be I need a extra module to buy or I need to program some code.
I hope someone can give me that solution.
