Free download:AuditTrail.mdb (intermediate)

This sample illustrates one way to produce a simple audit trail table containing: machine name, login name, user name (access security), record number, field name, original value, new value, and a date/time stamp. It tracks all changes made to a record in either the form or subform. It also tracks when new records are inserted and when records are deleted and the values of the deleted fields. It does not work properly for deleting if Cascade Deletes is set. It will show the deletes from the main form, but not the subform. Code is contained in Module1 and is called from each text box on each form. There are no doubt many improvements that can be made. This is just for illustration purposes.
