your data access tier. As of the writing of this book, the EF is scheduled to be released after the official release of the LINQ technologies. Due to the release schedule and the scope of the project itself, we re unable to cover it with the sufficient attention it deserves.

' We're outta here! frmMain_Exit: On Error GoTo 0 DoCmd.Close acForm, Me.Name ' In a production application, would quit here DoCmd.SelectObject acForm, "frmMain", True Exit Sub frmMain_Error: ErrorLog "frmMain", Err, Error Resume frmMain_Exit End Sub

After confirming that the user really wants to exit, the code looks at every open form All forms have a public cmdCancel_Click event procedure that this code can call to ask the form to clear any pending edits and close itself The DoEvents statement gives that code a chance to complete before going on to the next form Notice that the code skips the form named frmMain (the form where this code is running) If there were no errors closing all the forms, then the code opens a table that contains a count of how many times this application has run and the date of the last backup Every tenth time the application has run or every two weeks since the last backup, the code offers to create a backup of the application data.

If the user confirms creating a backup, the code creates a Backup subfolder if it does not exist, deletes the oldest backup if there are three or more in the folder, and then backs up the data using the CompactDatabase method of the DBEngine Next, the code checks to see if more than 20 errors have been logged by code running in the application If so, it opens a dialog box that gives the user the option to e-mail the error log, print out the error log, skip printing the error log this time, or turn off the option to print the log Because the error log option form opens in Dialog mode, this code waits until that form closes Finally, the code closes this form and selects an object in the Database window to reveal that window.

Summary

If this weren t a demonstration application, the code would use the Quit method of the Application object to close and exit Access This might seem like a lot of extra work, but taking care of details like this really gives your application a professional polish..

As noted earlier, the LawTrack Contacts sample application (Contacts.mdb) has an AutoKeys macro defined to intercept pressing Ctrl+F4. You can normally press this key combination to close any window that has the focus, but the application is designed so that you must close the frmMain form using the Exit button, not Ctrl+F4. You can create an AutoKeys macro to define most keystrokes that you want to intercept and handle in some other way. You can define something as simple as a StopMacro action to effectively disable the keystroke, create a series of macro actions that respond to the keystrokes, or use the RunCode action to call complex Visual Basic code. Figure 24-26 shows you the AutoKeys macro in the LawTrack Contacts database open in Design view.

21 The configuration manager creates the \Registry key object in the object manager namespace and copies the initial registry data passed by Winload into the HARDWARE and SYSTEM hives 22 The errata manager initializes and scans the registry for errata information, as well as the INF (driver installation file, described in 7) database containing errata for various drivers 23 SuperFetch and the prefetcher are initialized 24 The current time zone information is initialized 25 Global file system driver data structures are initialized 26 Phase 1 of debugger-transport-specific information is performed by calling the KdDebuggerInitialize1 routine in the registered transport, such as Kdcomdll 27 The Plug and Play manager calls the Plug and Play BIOS 28 The advanced local procedure call (ALPC) subsystem initializes the ALPC port type and ALPC waitable port type objects The older LPC objects are set as aliases 29.
