Indexing the content on your site in a way that facilitates effective, fast, and intelligent searching is a computationally expensive operation. Therefore, Drupal performs indexing in batches during scheduled cron.php tasks. This means that the search index will not be built, and the search functions will not work, unless you have configured scheduled cron.php tasks. The second ramification of this fact is that new content will not be found by searching until a cron.php task has been run, so you will need to schedule these tasks frequently enough to keep the index up-to-date. If your site receives new content frequently, the scheduled tasks must also be run relatively frequently. Refer to 6 for instructions on configuring scheduled tasks.

In this section, you will learn how to create a DTD for representing the structure of the Employees.xml file. Listing 5-1 shows the complete DTD for the document. Listing 5-1. DTD for Employees.xml <!ELEMENT <!ELEMENT <!ELEMENT <!ELEMENT <!ELEMENT <!ELEMENT <!ATTLIST employees (employee*)> employee (firstname,lastname,homephone,notes)> firstname (#PCDATA)> lastname (#PCDATA)> homephone (#PCDATA)> notes (#PCDATA)> employee employeeid CDATA #REQUIRED>

The SelectSingleNode() is very similar to the SelectNodes() method that you just learned, with one difference. Instead of returning a list of XmlNode objects in the form of an XmlNodeList, it simply returns the first matching XmlNode. To test this method, you can modify the previous example as shown in Listing 2-11.

Click on the Administration tab at the top to perform basic printer configurations (see Figure 1 15). If you d like to get more refined (and you know how to properly edit config files), the CUPS server has a configuration file that is editable from within the CUPS web interface. To access this file, select the Administration tab and click on the Edit Configuration File button under the Server heading. Security settings that can be altered by editing this file include the following: MaxCopies Port BrowseAllow BrowseAddress SystemGroup The Location s directive s Allow option NOTE: The Location directive has an Allow option that can be used to dictate which addresses are allowed to access shared printing and remote administration. AuthType AuthClass The Limit directive s Require User option

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(); }

This code assumes no usage of a server-side proxy and the presence of required security definitions in a crossdomain.xml file. The cross-domain policy file is discussed in Part 2 of this book. The trick of generating XML instead of HTML is very simple and straightforward, but it does have its limitations. Such a transformation assumes that you still keep all the logic and state in the server. But that is not the best way of using Flex, which is capable of managing state and interaction logic on the client. This capability is a big driver for rich and engaging experiences. In the next case, you ll see how a serverside service orientation could be an improvement over plain XML data access.

method on the class types in the setUp method. The setUp method also creates the service instance to be tested and assigns these mock controls to it. Each of the test methods follows the same basic outline: the test data is prepared, the mock controls are scripted, the service method is invoked, and the expectations are checked. Two parts of this process require further explanation. The scripting of the mock controls (the mock DAOs) is carried out by executing methods on the mock object itself. Listing 10-25 shows an example from the testFindUser() method.
