This treeview lists all the objects that it knows about for the instance of SQL Server to which it is connected. At the root of the tree, you can see the actual instance name to which you have connected. Below that, you see two main tree nodes: one to group together all the system databases that it found (in order to distinguish them from user databases you will see in a short while), and the other to manage all the user accounts that have access to connect and manipulate objects on the SQL Server instance. Across the top of EM, you have a toolbar with some buttons available to perform the more common operations. Table 3-1 lists the buttons with their functional descriptions. Table 3-1.

One possible approach is to continuously send a command to the sponsors so that they stay alive This can be accomplished with a simple KeepAlive() method that is called periodically from a background thread of the client application Another thing to watch out for is that the sponsor will be called from the NET Remoting framework s LeaseManager This call might well increase the time to live of your sponsor, depending on the RenewOnCallTime set in the configuration file Without taking special care here, you might end up with sponsors that keep running forever when Unregister() has not been called correctly for each and every sponsored object This could happen, for example, when the client application crashes or experiences a network disconnect To remove this potential problem, I suggest you add a DateTime instance variable that holds the time of the last call to the sponsor s KeepAlive() method.

Figure 13 5. IsolatedStorageSettingsDemo In the IsolatedStorageSettingsDemo application, as shown in Figure 13 5, when the Save button is clicked, the value in the Value text box will be added to the isolated storage settings using the key in the Key text box. Whenever new key-value pair data is added to the isolated storage settings, the key will be added to the list box of keys. When any of the keys in the list box of keys is selected, the Key text box and the Value text box will be populated with the data retrieved from the isolated storage settings. The Delete button will delete the selected key from the isolated storage settings. To build the demo, you ll first create a new project, then add XAML markup to create a new main page and its controls. Finally, you ll add behavior to the application with C# code that makes use of isolated storage APIs to save and retrieve key-value pairs.
