If, for any reason, you find that Ubuntu s default partitioning choices are not for you, you can opt to manually edit the partition table. There are essentially two stages to work through if you choose this option: You re given the chance to repartition the disk manually. You can resize or delete any existing partitions and create the partitions Ubuntu needs. While creating/editing the partitions, you ll be asked to assign mount points. You ll be prompted to tell Ubuntu which of the partitions on the disk it should use for the root file system (that is, the main partition for Ubuntu s use) and which should be used for the swap partition. Manually partitioning offers ultimate flexibility but requires a relatively high level of knowledge of how Ubuntu works. Therefore, we recommend that only experts undertake this step, unless you have no other choice because the default Ubuntu partitioning choices do not offer what you need or do not work properly for you. In the following steps, we explain how to resize an existing partition, create the new partitions that Ubuntu needs, and assign mount points so that Ubuntu is able to use them.

Note .NET assemblies often contain a large amount of code. For example, a single assembly may contain as

xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="employees"> <xs:complexType> <xs:sequence> <xs:element name="employee" type="EmployeeType" minOccurs="0" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType name="EmployeeType"> <xs:all> <xs:element name="firstname" type="NameSimpleType" /> <xs:element name="notes" type="NotesSimpleType" /> <xs:element name="lastname" type="NameSimpleType" /> <xs:element name="homephone" type="PhoneSimpleType" /> </xs:all> ... The Click event handler of the Validate button is shown in Listing 13-25. Listing 13-25. Validating Against the XSD Schema private void button1_Click(object sender, EventArgs e) { XDocument doc = XDocument.Load(textBox1.Text); XmlSchemaSet schema=new XmlSchemaSet(); schema.Add(null,textBox2.Text); ValidationEventHandler handler = new ValidationEventHandler(MyHandler); doc.Validate(schema, handler); } public void MyHandler(object sender, ValidationEventArgs e) { MessageBox.Show(e.Message); } The code loads the source XML document in an instance of the XDocument class. It then creates an XmlSchemaSet and adds the specified XSD schema to it using the Add() method. The Validate() extension method of the XDocument class accepts two parameters: XmlSchemaSet and an event handler that gets called if validation fails. The event handler is of type ValidationEventHandler. The MyHandler() method acts as the event handler in our example. The validation is triggered by calling the Validate() method. If there are any validation errors, the MyHandler() event handler gets invoked. The MyHandler() event handler receives a parameter of type ValidationEventArgs. The Message property of the ValidationEventArgs class provides information about the validation errors. In order to test the code, remove the employeeid attribute from the first <employee> element of the Employees.xml file and run the application. Figure 13-17 shows a validation error message after a sample run.

be important if users are registering accounts for malicious purposes, but not necessarily posting. This is a glaring omission, which luckily can be rectified by installing a modification known as Log Registration IP. I consider it vital, and I highly recommend this feature, even if you do not install any additional ones. You can obtain the Log Registration IP modification from http://www.phpbbhacks.com/download/2975.
