NOTIFYING AND LOGGING USERS OUT OF AN APPLICATION

When dealing with live systems, you need a mechanism for logging and keeping people out of an application's back end. As with most system problems, a number of different solutions exist.

One solution to keeping a property on the back end is to keep track of whether users are to be logged out. The preceding section describes the method for creating a property for a database. The difference is that this time, you have to use the back-end database, VideoDat.mdb, rather than the front-end database. Figure 26.3 shows the database properties of VideoDat.mdb, with a LogUserOut property added. You can examine this property from VBA and act accordingly. VideoDat.mdb, like VideoApp.mdb, is on the accompanying CD-ROM in the \Examples folder.
