Listing 2-15. Deleting a Node private void button3_Click(object sender, EventArgs e) { XmlNode node = doc.SelectSingleNode("//employee[@employeeid='" + comboBox1.SelectedItem + "']"); if (node != null) { doc.DocumentElement.RemoveChild(node); } doc.Save(Application.StartupPath + "/employees.xml"); UpdateLabel(); } The code retrieves the node that we wish to delete by using the SelectsSingleNode() method. To delete a node from the ChildNodes collection, the XmlNode class provides a method called RemoveChild(). The RemoveChild() method accepts a reference to the XmlNode that is to be removed from the ChildNodes collection. In our case, we wish to remove the entire <employee> node, which is a child node of the <employees> root element. Hence the code calls the RemoveChild() method on the DocumentElement, that is, the root node of the document. After the node is deleted, the file is saved to disk by using the Save() method of the XmlDocument class. The UpdateLabel() helper method simply updates the current record number displayed on the status label.

document by answering questions and following a wizard-based interface. This replaces the templatebased approach within Microsoft Office, although it s worth noting that OpenOffice.org is still able to use templates. A wizard will usually offer a variety of document styles. Some wizards will even prompt you to fill in salient details, which they will then insert into your document in the relevant areas. Note that within some components of OpenOffice.org, such as Writer, the wizards offered on the File menu won t work unless Java Runtime Environment (JRE) software is installed. This can be done quickly and easily by closing any open OpenOffice.org applications, opening the Ubuntu Software Center (Applications Ubuntu Software Center), and installing the following programs: Standard Java or Java-compatible runtime (default-jre) Office productivity suite (arch-independent Java support files [openoffice.orgjava-common])

In this example, you use the ExecuteReader method to retrieve and then output the first and last names of all the employees in the Employees table. As with ExecuteScalar(), ExecuteReader() takes the CommandText property and sends it to the database using the connection from the Connection property. When you use the ExecuteScalar method, you produce only a single scalar value. In contrast, using ExecuteReader() returns a SqlDataReader object.

You will need to type your password when prompted. The software will probably be in the 200MB range, so it might take a while to download. Installation is automatic; after it has finished, close the Ubuntu Software Center and log out. When you log in again, open any OpenOffice.org application to test the installation by starting a wizard.

The code that adds a new employee is a bit lengthier than our previous examples. It is more interesting too. You will now learn how to create XML document contents from the ground up. Creating elements, attributes, text nodes, and CDATA sections will all be demystified in this section. First of all, let s count the elements, attributes, and nodes that we need to create in order to add a new employee to our XML document. Here is a list of nodes that we need to add: An <employee> element A <firstname> element A <lastname> element A <homephone> element A <notes> element An employeeid attribute for the <employee> element A text node for the <firstname> value A text node for the <lastname> value A text node for the <homephone> value A CDATA section for the <notes> value

Note In case you re wondering why this useful software isn t included by default, you can blame the fact that it s over 200MB. Put simply, it just won t fit on the Ubuntu installation CD-ROM.
