Look at figure 4.19 and note how the result is different than with a grouping operation. As with nested queries (see figure 4.17), publishers with no books appear in the results this time. After group joins, we ll now take a look at inner joins, left outer joins, and cross joins. Inner join An inner join essentially finds the intersection between two sequences. With an inner join, the elements from two sequences that meet a matching condition are combined to form a single sequence. The Join operator performs an inner join of two sequences based on matching keys Figure 4.19 Group join result extracted from the elements. For example, it can be used to display a flat view of publishers and books like the one in figure 4.20. The query to use to get this result looks like listing 4.24. This query is similar to the one we used in the group join sample. The difference here is that we don t use the into keyword to group the elements. Instead, the books are projected on the publishers. As you can see in figure 4.20, the result sequence contains an element for each book. In our sample data, one publisher isn t associated with any book. Note that this Figure 4.20 Inner join result publisher isn t part of the results. This is why this kind of join operation is called an inner join. Only elements from the sequences that have at least one matching element in the other sequence are kept. We ll see in a minute how this compares with a left outer join.

Figure 18-10. When Windows detects that you ve inserted a new disk (or other media) into a removable storage device, it asks how you want to handle the content.

4. In the Auditing Entry For dialog box for the file or folder, select the Successful check box, the Failed check box, or both check boxes for the events that you want to audit. Table 13-4 describes the events that can be audited for files and folders.

The Windows AutoPlay settings allow you to define different default actions for different types of content. For instance, you can specify that you want music CDs to play automatically in Windows Media Player or another application, while disks that contain mixed content should open in a Windows Explorer window so that you can copy them to a local drive.

User Activity That Triggers the Event Performing any type of access to the audited file or folder Running a program or gaining access to a folder to change directories Displaying the contents of a file or a folder Displaying the attributes of a file or folder Changing the contents of a file or folder or creating new folders or files in a folder Changing attributes of a file or folder Deleting a file or subfolder in a folder Deleting a file or folder Viewing permissions for the file owner for a file or folder Changing permissions for a file or folder Taking ownership of a file or folder

Using object-oriented programming practices adds functionality to the business domain by taking base object structures and extending them to add the custom business logic. Prior to .NET 2.0, the main way to extend those structures was by inheriting from a base class. With .NET 2.0, Microsoft introduced the concept of partial classes. With partial classes, we can isolate specific functionality sets in separate files and then allow the compiler to merge them into a single class. The usefulness of partial classes is particularly evident when dealing with generated code. By default, both of the automated generation tools we ve explored (the designer and SqlMetal) generate the class definitions as partial classes. As a result, we can use either tool to dynamically generate our entities and enforce customized business logic in separate classes. Let s explore a simple use case that will entail adding a property to concatenate and format the author s name based on the existing properties in the Author object. In chapter 7, we defined the mapped version of our Author class. When we defined it manually, we set it up as public class Author. When we later let the tools generate our Author class, they defined it as a partial class. Because it was created as a partial class, we can create a second class file to define the other part. Listing 8.24 shows the code to add functionality to our Author class by using a partial class definition.

Disabling AutoPlay Some people see AutoPlay as a nuisance instead of a convenience. If you re in that camp, you can disable AutoPlay altogether as explained in the following procedures. If you re running Windows XP Professional, use Group Policy, as follows:

5. In the Apply Onto list, specify where objects are audited. By default, this box is set to This Folder, Subfolders And Files, so any auditing changes that you make to a parent folder also apply to all child folders and all files in the parent and child folders. Where objects are audited depends on the selection in the Apply Onto list and whether the Apply These Auditing Entries To Objects And/Or Containers Within This Container Only check box is cleared as shown in Table 13-5.
