The Subversion developers, many of whom are longtime CVS users and developers, have taken great care to preserve the portions of CVS that are most useful, while simultaneously improving upon it in countless ways Specifically, Subversion provides the following big-ticket improvements over CVS, described in the next section..

In this example, you ll see what alternative methods you can employ to deal with Web list controls that allow multiple selections. You can t rely on using the SelectedItem property, because that will return only the first item selected in the list. Instead, you must iterate through the list each time and build up a SQL query accordingly.

Some Android handsets, like the T-Mobile G1, offer a slide-out keyboard that triggers rotating the screen from portrait to landscape orientation. Other handsets might use accelerometers to determine screen rotation, as the iPhone does. As a result, it is reasonable to assume that switching from portrait to landscape orientation and back again may be something your users will want to do. As you ll learn in this chapter, Android has a number of ways for you to handle screen rotation, so your application can properly handle either orientation. But realize that these facilities just help you detect and manage the rotation process. You are still required to make sure you have layouts that look decent in each orientation.

1. In Visual Web Developer, create a new Web Form called List_DataReader_Multiple.aspx. 2. Change the <title> of the page to Multiple Selection Using a DataReader. 3. Make sure you ve included the correct Import statements at the top of the page. <%@ Page Language="C#" %> <%@ Import Namespace="System.Data.SqlClient" %> <%@ Import Namespace="System.Text" %> 4. In the Design view, add a ListBox, a Button, and a GridView to the page. Change the Text for the Button to Select. You can use a table to lay out the Web controls in a more userfriendly manner, as shown in Figure 6-17.

Whereas CVS works in terms of individual files, Subversion versions entire trees, which allows it to track historical data that CVS simply can t store. Many CVS users will admit to being shocked when they first realized there was no simple way to rename a file or delete a directory, or that they couldn t have an empty directory in their CVS repository.

Figure 6-17. Laying out the Web list controls 5. For the ListBox, set DataTextField to ManufacturerName, DataValueField to ManufacturerID, and SelectionMode to Multiple. 6. The code for the Page_Load event is pretty much the same as in the previous DataReader example: protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack == false) { // create SqlConnection object string ConnectionString = ConfigurationManager. ConnectionStrings["SqlConnectionString"].ConnectionString; SqlConnection myConnection = new SqlConnection(ConnectionString); // create SqlCommand object SqlCommand myCommand = new SqlCommand(); myCommand.Connection = myConnection;

By default, when there is a change in the phone configuration that might affect resource selection, Android will destroy and re-create any running or paused activities the next time they are to be viewed. While this could happen for a variety of different configuration changes (e.g., change of language selection), it is most likely to trip you up for rotations, since a change in orientation can cause you to load a different set of resources (e.g., layouts). The key here is that this is the default behavior. It may even be the behavior that is best for one or more of your activities. You do have some control over the matter, though, and can tailor how your activities respond to orientation changes or similar configuration switches.

try { // open the database connection myConnection.Open(); // set up SQL query for Manufacturer table myCommand.CommandText = "SELECT ManufacturerID, ManufacturerName FROM Manufacturer"; // run query SqlDataReader myReader = myCommand.ExecuteReader(); // set up the list control ListBox1.DataSource = myReader; ListBox1.DataBind(); // close the reader myReader.Close(); } finally { // always close the connection myConnection.Close(); } } } 7. Add a Click event handler for the Button. First, add the code to create the Command and Connection objects, and then open the connection: protected void Button1_Click(object sender, EventArgs e) { // create SqlConnection object string ConnectionString = ConfigurationManager. ConnectionStrings["SqlConnectionString"].ConnectionString; SqlConnection myConnection = new SqlConnection(ConnectionString); // create SqlCommand object SqlCommand myCommand = new SqlCommand(); myCommand.Connection = myConnection; try { // open the database connection myConnection.Open();
