When this feature is not in use, you must issue the OPEN MASTER KEY statement and supply the same password initially used to encrypt the DMK whenever you need to use it The potential downside to encrypting your DMK with the SMK is that any member of the sysadmin server role can decrypt the DMK You can use the ALTER MASTER KEY statement to change the method SQL Server uses to decrypt the DMK Listing 8-3 shows how to turn off encryption by SMK for a DMK Listing 8-3 Turning Off DMK Encryption by the SMK ALTER MASTER KEY DROP ENCRYPTION BY SERVICE MASTER KEY; When the DMK is regenerated, all the keys it protects are decrypted and reencrypted with the new DMK The FORCE keyword is used to force SQL Server to regenerate the DMK even if there are decryption errors.

' Use this value in your page... End Sub you can simply ask the server-side widget directly via the Text property for use in your program: Protected Sub btnGetFormData_Click(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles btnGetFormData.Click ' Get value for a widget with ID txtFirstName. Dim firstName As String = txtFirstName.Text ' Use this value in your page... End Sub Not only does this approach lend itself to solid OO principles, but also you do not need to concern yourself with how the form data was submitted (GET or POST) before obtaining the values. Furthermore, working with the widget directly is much more type-safe, given that typing errors are discovered at compile time rather than runtime. Of course, this is not to say that you will never need to make use of the Form or QueryString property in ASP.NET; rather, the need to do so has greatly diminished and is usually optional.

Another very important member of HttpRequest is the IsPostBack property. Recall that postback refers to the act of returning to a particular web page while still in session with the server. Given this definition, understand that the IsPostBack property will return true if the current HTTP request has been sent by a currently logged on user and false if this is the user s first interaction with the page. Typically, the need to determine whether the current HTTP request is indeed a postback is most helpful when you wish to perform a block of code only the first time the user accesses a given page. For example, you may wish to populate an ADO.NET DataSet when the user first accesses an *.aspx file and cache the object for later use. When the caller returns to the page, you can avoid the need to hit the database unnecessarily (of course, some pages may require that the DataSet always be updated upon each request, but that is another issue). Assuming your *.aspx file has handled the page s Load event (described in detail later in this chapter), you could programmatically test for postback conditions as follows: Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load ' Only fill DataSet the very first time ' the user comes to this page. If Not IsPostBack Then ' Populate DataSet and cache it! End If ' Use cached DataSet. End Sub

combinations of the layout containers, and you threw the GridSplitter into the mix to make resizable split pages. You even considered how to build your own layout containers to get custom effects. Finally, you saw how to take control of the top-level user control that hosts your entire layout by resizing it, rescaling it, and making it fill the entire screen.

As with the SMK, the FORCE keyword should be used only as a last resort You can expect to lose data if you have to use FORCE You can also back up and restore a DMK with the BACKUP MASTER KEY and RESTORE MASTER KEY statements The BACKUP MASTER KEY statement is similar in operation to the BACKUP SERVICE MASTER KEY statement When you back up the DMK, you must specify the password that SQL Server will use to encrypt the DMK in the output file When you restore the DMK, you must specify the same password in the DECRYPTION BY PASSWORD clause to decrypt the DMK in the output file In addition, you must specify an encryption password that SQL Server will use to encrypt the password in the ENCRYPTION BY PASSWORD clause Listing 8-4 demonstrates backing up and restoring a DMK..
