A data table is made up of columns and rows. Columns are also referred to as fields, and rows are sometimes called records. Still, in a relational database, a good deal of hidden logic exists behind a simple list of data rows. Because this chapter covers only the departments list, you ll only need to create one data table: the Department table. This table will store your departments data and is one of the simplest tables you ll work with. With the help of tools such as Visual Studio or Visual Web Developer, it s easy to create a data table in the database if you know what kind of data it will store. When designing a table, you must consider which fields it should contain and which data types should be used for those fields. Besides a field s data type, there are a few more properties to consider; we ll learn about them in the following pages. To determine which fields you need for the Department table, write down a few examples of records that would be stored in that table. Remember from the previous figures that there isn t much information to store about a department just the name and description for each department. The table containing the departments data might look like Figure 4-6.

Listing 9-17. Retrieving a Value Stored in a Session Variable private void button2_Click(object sender, EventArgs e) { Service proxy = new Service(); proxy.CookieContainer = cookiecontainer; MessageBox.Show(proxy.GetNameFromSession()); } The code creates an instance of the proxy class as before. It then sets the CookieContainer property of the proxy to the CookieContainer object we created previously. This way, the previously issued session identifier can be passed back to the web service. Finally, the GetNameFromSession() method is called. The value returned by the GetNameFromSession() method is displayed in a message box.

The way you work with data tables in a relational database is a bit different from the way you usually work on paper. A fundamental requirement in relational databases is that each data row in a table must be uniquely identifiable. This makes sense because you usually save records into a database so that you can retrieve them later; however, you can t do that if each row isn t uniquely identifiable. For example, suppose you add another record to the Department table shown previously in Figure 4-6, making it look like the table shown in Figure 4-7.

While developing clients for a web service, you add a web reference to the web service by specifying the URL of the .ASMX file, and it is this URL that Visual Studio uses when generating the required proxy object. However, after adding a web reference, the web service could be moved to some other location. In such cases, the easiest way out is to re-create the proxy object. But what if this happens after you deploy your web service client It would be nice if you could change the URL programmatically so that even if the original web service is moved, your clients need not be recompiled. The Url property of the web service proxy class allows you to do just that. Listing 9-18 shows the relevant code. Listing 9-18. Changing the Web Service URL at Run Time Service proxy=new Service(); proxy.Url="http://localhost/newlocation/Service.asmx";
