Re: [MS_AccessPros] Creating an executable in Access 2007

 

Sally

If you create an .accde file and set some of the database properties so that the Navigation Pane and default ribbons (menus) are hidden plus disallow context menus you can do a decent job of keeping the average user out of the tables. But it isn't perfect by any means.

A better way, now that ULS is not supported in the new file format, is to move your tables to SQL Server (the Express version is free). This gives you control over permissions right down to specific fields(columns) in tables. I do this on all my projects. I even base my form and report exposure to the user through user and user group tables.

It can be as simple or complicated as you want. The more you work with VBA code, the more ways you'll find to limit user access.
