Listing 7-19. Declaring a Typed DataSet Variable private string strConn = @"data source=.\sqlexpress; initial catalog=northwind;integrated security=true"; EmployeesDataSet ds = new EmployeesDataSet(); SqlDataAdapter da = new SqlDataAdapter(); SqlConnection cnn; Notice the line marked in bold. The code declares a variable of our typed DataSet, which bears the same name as the DataSet XSD schema file. This typed DataSet is filled in the Load event of the form. The code in the Load event remains the same as before but for the sake of completeness is given in Listing 7-20. Listing 7-20. Filling a Typed DataSet private void Form1_Load(object sender, EventArgs e) { cnn = new SqlConnection(strConn); SqlCommand cmdEmployees = new SqlCommand(); cmdEmployees.CommandText = "SELECT * FROM employees"; cmdEmployees.Connection = cnn; da.SelectCommand = cmdEmployees; da.Fill(ds, "Employees"); FillEmployees(); } The code uses a SqlDataAdapter and calls its Fill() method to populate the typed DataSet. One thing to note here is that the name of the DataTable specified in the Fill() method must match the name of the DataTable that you created in the typed DataSet. Listing 7-21 shows the modified version of the code responsible for inserting, updating, and deleting DataRow objects. Listing 7-21. Inserting, Updating, and Deleting Data from a Typed DataSet private void button2_Click(object sender, EventArgs e) { EmployeesDataSet.EmployeesRow row = ds.Employees.NewEmployeesRow(); row.EmployeeID = int.Parse(comboBox1.Text); row.FirstName = textBox1.Text; row.LastName = textBox2.Text; row.HomePhone = textBox3.Text; row.Notes = textBox4.Text; ds.Employees.AddEmployeesRow(row); FillEmployees(); }

Finally we create a context object to represent the process of establishing the authentication with the server. As yet, this context is unauthenticated, which implies that the user principal is not yet authenticated on both of the machines that will share the context:

ASP .NET AJAX provides functions that allow you to check if the start or end of a string matches a specific value. These return a Boolean indicating whether there is a match. Here s an example:

GSSContext context = manager.createContext( serverName, krb5Mechanism, userCreds, GSSContext.DEFAULT_LIFETIME);

private void button1_Click(object sender, EventArgs e) { string id = comboBox1.SelectedItem.ToString(); EmployeesDataSet.EmployeesRow[] rows = (EmployeesDataSet.EmployeesRow[])ds.Employees.Select("EmployeeID=" + id); rows[0].BeginEdit(); rows[0].FirstName = textBox1.Text; rows[0].LastName = textBox2.Text; rows[0].HomePhone = textBox3.Text; rows[0].Notes = textBox4.Text; rows[0].EndEdit(); } private void button3_Click(object sender, EventArgs e) { string id = comboBox1.SelectedItem.ToString(); EmployeesDataSet.EmployeesRow[] rows = (EmployeesDataSet.EmployeesRow[])ds.Employees.Select("EmployeeID=" + id); rows[0].Delete(); FillEmployees(); } Notice the changes made to the original code. In the Click event handler of the Insert button, the new DataRow is created by calling NewEmployeesRow(). The typed DataSet automatically show the available DataTable objects as properties, and each DataTable provides the NewEmployeesRow() method to create a new row. The newly created row is of type EmployeesRow, which is a nested class generated by Visual Studio in the EmployeesDataSet class. EmployeesRow exposes each column of the row as a property, and these properties can then be assigned new values. The newly created row is then added to the Employees DataTable by using its AddEmployeesRow() method. There are similar modifications in the Click event handlers of the Update and Delete buttons.

The client and server code invokes the methods of the GSSContextUtil class to establish a secure context, and we invoke a method in the Authentication class that we ve already discussed in order to establish a login prior to this. The code for the client is

var str = "This is a string"; var a = str.startsWith('this'); //returns 'false' because it is case insensitive var a = str.endsWith('string'); //returns 'true'

Though Visual Studio provides a visual way to create typed DataSets, the .NET Framework also provides a command-line tool called xsd.exe that can generate typed DataSets for you. The tool accepts an XSD schema and outputs the typed DataSet class. Though we will not discuss the xsd.exe tool at great length, here is a sample use of it: xsd.exe /d /l:CS Employees.xsd /n:MyTypedDataSets The /d switch indicates that the tool should generate a typed DataSet. The /l switch specifies the language used to create the output typed DataSet class. In our example, we specify the language as C# (CS). Finally the /n switch specifies the namespace in which the typed DataSet class will be placed. The output of the preceding command will be a class file named Employees.cs. You can compile this class file separately or along with your other classes.

// AuthClient.java import java.io.*; import java.net.Socket; import javax.security.auth.Subject; import org.ietf.jgss.GSSContext; public class AuthClient { public AuthClient(String server, int port) throws IOException { socket = new Socket(server, port); output = socket.getOutputStream(); input = socket.getInputStream(); } public void close() throws IOException { socket.close(); } public void createContext( String clientPrincipal, String clientPassword, String serverPrincipal) throws Exception { Authentication.setKerberosSystemProperties(); Subject subject = Authentication.jaasLogin( "ClientAuthentication", clientPrincipal,

String trimming involves removing whitespace from the start and end of the string. The ASP .NET AJAX extensions offer three methods:
