Microsoft Access database applications are normally planned, designed and built using the standard single file format in either .MDB or the newer .ACCDB (Access 2007/2010) and then distributed with all the objects (Tables, Queries, Forms, Reports, Macros and Modules -VBA code) fully accessible with the standard default settings applied.
To help lock down and prevent certain objects especially Forms, Reports and any code being modified (via the design mode), you can convert your database file into an ‘executable‘ file format where the .MDB becomes a copy as an .MDE and the .ACCDB to a .ACCDE.
