[OnDeserializing] public void OnDeserializing(StreamingContext context) { //no code here } [OnDeserialized] public void OnDeserialized(StreamingContext context) { strFName = Decode(strFName); strLName = Decode(strLName); strHPhone = Decode(strHPhone); strNotes = Decode(strNotes); } The four methods are marked with the [OnSerializing], [OnSerialized], [OnDeserializing], and [OnDeserialized] attributes. These attributes allow you to customize the serialization and deserialization process by using pre- and post-methods: The method marked with [OnSerializing] is automatically called by the serialization framework before the data is serialized. The method marked with [OnSerialized] is called when the serialization is complete. Similarly, the methods marked with [OnDeserializing] and [OnDeserialized] are called before and after the deserialization operation. All these methods must accept a parameter of type StreamingContext. The StreamingContext parameter provides additional information about the serialization or deserialization process. In our example, the OnSerializing() method calls the Encode() helper method that we created earlier to encode the variable values into Base64 format. Thus the data being serialized is not a plain string but a Base64 string. After the serialization is complete, we may still need the same data in plain-string format. That is why the Decode() method is called in the OnSerialized() method. The OnDeserializing() method doesn t include any code in our example. However, if you wish to execute some code before deserialization takes place, you can add your custom logic in this method. After the previously serialized data is deserialized, it should give us the values in plain-string format and not in Base64 format. Hence the OnDeserialized() method calls Decode() and converts the Base64 values into plain text. Figure 8-9 shows a sample run of the application.

IIS is the web server included by Microsoft in its server-capable Windows versions. These are Windows Vista Business, Windows Vista Home Premium, Windows XP Professional, Windows XP Media Center Edition, Windows 2000 Professional, Server, Advanced Server, and Windows Server 2003 but it s not installed automatically in all versions. IIS isn t available (and can t be installed) with Windows XP Home Edition or Windows Vista Home Basic. To follow the examples in the book, you can use either IIS or the web server included in Visual Web Developer 2008 Cassini. Using Cassini, you can run the ASP.NET Web Application from any physical folder on your disk. For example, when creating the Web Site project, you can specify as destination a folder such as C:\BalloonShop. Whenever possible, we suggest that you use IIS, because this resembles more accurately the deployment environment in which the ASP.NET application will ultimately run on. To install IIS under Windows Vista, follow these steps: 1. In the Control Panel, select Programs Programs and Features. 2. Choose Turn Windows features on or off.

To keep your hard drive tidy, we ll use a single web application for all the exercises in this book, which will be located in the C:\BalloonShop\ folder. (Of course, you can use a different folder or location if you prefer.) We ll cover the web application setup steps for Windows Vista. IIS 7 in Windows Vista supports multiple root web sites on the same web server, so we ll create a web site called, which will point to the C:\BalloonShop\ folder that you create for your application. This way, your new web site will not interfere with the existing http://localhost/. IIS 5 and 6 don t support multiple root web sites, so if you have Windows XP, just stick to http://localhost/ and skip the following exercise don t worry, the whole application functionality will remain the same, except the URL you ll use to access BalloonShop during development. Follow these steps to prepare your BalloonShop web site in Windows Vista: 1. First, you need to add the host to the Windows hosts file. This will tell Windows that all domain name resolution requests for should be handled by the local machine instead of your configured DNS.
