I have made an .mdb file that I want to distribute to a variety of users that will each have their own copy. The underlying data does not need to be updated. The database will be used only to query the data (dialog forms are used to get query criteria from users and reports pop up automatically). What can I do to secure the database from users changing or corrupting the underlying data and the forms. I've seen the FAQ's on MDE files--anything else? Can I lock the tables? Thanks!
