Although the binding that has just been defined works quietly behind the scenes, it is not the only way to bind configuration settings to control properties. Simple assignment can be used to retrieve and update the setting information. And if the settings are defined properly, the Properties.Settings class will be automatically extended so that newly created settings show up as properties on the Properties.Settings class. For example, if a setting called demoFormPosition has been created, you would access with the following code:

Microsoft doesn't document a way to prevent the setup program from installing Windows Messenger a common request. I've added the component msmsgs to Listing 15 2, however, which prevents the setup program from installing it. The file Sysoc.inf, which you learn about in the next section, hides this component in Windows Components Wizard. You can edit that file to show Windows Messenger in the wizard, but doing so relies on users to remove Windows Messenger. Instead, you can add the component to the [Components] section of your answer file to prevent the setup program from installing it. This is a great technique for preventing the operating system from installing things such as the games, but it doesn't prevent the installation of components such as Movie Maker, because the [Components] section doesn't include settings for those components. You can use it to prevent the installation of Windows Media Player and Windows Messenger, though, which strikes two 303

You can use the CLR integration in SQL Server to create data types that do not already exist within SQL Server. You must enable the CLR within the SQL Server Surface Area Configuration utility to use a CLR UDT. If the CLR is ever disabled, all columns defined with CLR UDTs will no longer be accessible. To create a CLR UDT, you must create a class by using one of the .NET programming languages, such as C#, that conforms to the UDT specification. The class then has to be compiled to a dll. A member of the sysadmin fixed server role must register the assembly in the SQL Server instance. Only then can you implement a CLR UDT within a database.

sions required by an application. However, if you develop and test your application using SecurityAction.RequestOptional CAS declarations, the runtime grants your assembly only those permissions you specify. If you add code that requires additional permissions, the runtime throws System.Security.Policy.PolicyException, indicating the required permission. You can then add another SecurityAction.RequestOptional CAS declaration, ensuring that you maintain an accurate list of required permissions.

Full database backups back up all the data in the database. Differential database backups back up all the data that has been changed since the last full backup. Transaction log backups back up the active portion of the transaction log that is, the portion that has been active since the last transaction log backup. The active portion of the transaction log the part that has not yet been backed up is known as the tail of the log. You should perform a tail-log backup before
