Except on computers that are part of a domain (a configuration that doesn t support the Welcome screen), Windows XP is configured by default to use the Welcome screen. Tip Log on using hidden accounts While the Welcome screen is displayed, you can display the Log On To Windows dialog box shown in Figure 7-9 by pressing Ctrl+Alt+Delete twice. This allows you to log on using an account that isn t shown on the Welcome screen (Administrator, for example). Note, however, that this trick works only when no other users are logged on. If your system is not using the Welcome screen and you want it to, follow these steps:

You are a network administrator for Contoso Pharmaceuticals. Several servers in your organization store trade secrets that must be protected from attack. Firewalls and virus scanners are in place to keep these servers safe. In addition, you ve configured audit ing settings so that these servers will not lose any security auditing information. You are at home after the workday, and you receive a phone call from Josh Barnhill. Josh is a member of the Server Operators group. He says that Server2 stopped functioning. There is a message in the Log On To Windows box that reads The Security Log On This System Is Full. Only administrators can log on to fix the problem. Josh cannot log on. He needs your help. In order to experience this situation, first prepare Server2. 1. Log on to Server2 using the Administrator user name and password. 2. Click Start, click Run, and type gpedit.msc. Server2 s Local System Group Policy Object Editor opens.

2 Click the Change The Way Users Log On Or Off link. If a warning message about offline files appears, simply click Cancel. As the message points out, offline files and Fast User Switching are incompatible, but you don t need to disable offline files to enable only the Welcome screen. 3 Select Use The Welcome Screen, and then click Apply Options.

By default, whenever the screen saver kicks in and you subsequently press a key or move the mouse, you ll find yourself back at the Welcome screen. This provides some protection against someone using your computer when you ve stepped away. To resume working, you ll need to click your name and enter your password. If you d rather return to work without going through these extra steps, do the following:

This produces the display shown in figure 5.2 for an ascending sort by title. Figure 5.3 shows the display for a descending sort by title. After showing you how to parameterize the condition of a query s where clause and use a dynamic sort order, we d like to show you a more advanced scenario. This new example will demonstrate how to dynamically define a query, including or excluding clauses and operators depending on the context. This is something you d want to achieve often, so queries can take into account the application s context, settings, or the user s input. Conditionally building queries The previous examples showed how to customize queries by changing the values they use as well as the sort order. A new example will show you how to add criteria and operators to a query dynamically. This technique allows us to shape queries based on user input, for example. Let s consider a common scenario. In most applications, data isn t presented to the user directly as is. After being extracted from a database, an XML document, or another data source, the data is filtered, sorted, formatted, and so on. This is where LINQ is of great help. LINQ queries allow us to perform all these data manipulation operations with a nice declarative syntax. Most of the time, the data is filtered and dynamically shaped based on what the user specifies.

1 Right-click the desktop, and choose Properties to open the Display Properties dialog box. 2 Click the Screen Saver tab. 3 Clear the check box labeled On Resume, Display Welcome Screen (if Fast User Switching is enabled) or On Resume, Password Protect (if Fast User Switching is disabled).
