Bootmgr s BIOS-interfacing functions briefly switch the processor back to a mode in which services provided by the BIOS can be executed, called real mode Bootmgr next reads the BCD file from the \Boot directory using built-in file system code Like the boot sector s code, Bootmgr contains read-only NTFS code (Bootmgr also supports other file systems, such as FAT, El Torito CDFS, UDFS, and WIM files); unlike the boot sector s code, however, Bootmgr s file system code can read subdirectories Note Bootmgr and other boot applications can still write to preallocated files on NTFS volumes, because only the data needs to be written, instead of performing all the complex allocation work that is typically required on an NTFS volume This is how these applications can write to bootsectdat, for example Bootmgr next clears the screen.

Automating Your Application with Visual Basic current request record (EmployeeNumber, CheckInDate, CheckOutDate, and Notes). The code starts a transaction because it must simultaneously enter a ReservationID in both the tblReservationRequests table and the tblReservations table. If either fails, the error-trapping code rolls back both updates. Notice that the code opens the tblReservations table for append only to make the insert of the new reservation more efficient.

As you learned in 3, Designing Your Database Application, storing a calculated value in a table isn t usually a good idea because you must write code to maintain the value. But sometimes, in a very large database, you need to calculate and save a value to improve performance for searching and reporting. The Housing Reservations application isn t all that large but it could be in real life. I chose to store the calculated total charge for each reservation to show you some of the steps you must take to maintain a value like this. Users can create and edit reservation requests, but the creation of the reservation records that contain the calculated value is controlled entirely by code, so maintaining the calculated TotalCharge value in this application is simple. You ve already seen the one place where a new reservation record is created in the public Bookit function in the frmUnbookedRequests form. The little piece of code that calculates the value is as follows:

Calculate the total charge rstRes!TotalCharge = ((Int(Me.CheckOutDate - Me.CheckInDate) \ 7) * _ curWeekly) + _ ((Int(Me.CheckOutDate - Me.CheckInDate) Mod 7) * _ curDaily)

C covered more than what comes with LINQ, but a good deal of what is now included as part of the LINQ technologies was already present in C . The C project was conceived to experiment with integrated queries, mixing C# and SQL, C# and XQuery, and so on. This was carried out by researchers such as Erik

However, in many applications, you might not be able to control the editing of a calculated value this closely. You need to carefully consider the ramifications of saving a calculated value in your table and perhaps write code that an administrator can run to periodically verify that any saved calculated value hasn t become out of sync with the other fields used to perform the calculation.

In a typical application, you ll probably spend 80 to 90 percent of your coding effort in event procedures for your forms. That doesn t mean that there aren t many tasks that you can automate on reports. This last section shows you just a few of the possibilities.

Have you ever wanted to create a mailing label report and come up with a way to use up the remaining labels on a partially used page You can find the answer in the LawTrack Contacts sample application (Contacts.mdb). Let s say you want to send a promotional mailing to all contacts who own the Single User product offering them an upgrade to Multi-User. Open the main switchboard form (frmMain), click Contacts, and then click Search in the Select Contacts pop-up window. Perform a search for all contacts who own the Single User 917
