You are developing an outofbrowser application by using Silverlight 4. The application contains the following code segment. (Line numbers are included for reference only.)

01 public partial class App : Application
02 {
03 public App()
04 {
05 this.Startup += this.Application_Startup;
06 InitializeComponent();
07 }
08 void Application_Startup(object sender, StartupEventArgs e)
09 {
10 this.RootVisual = new MainPage();
11
12 }
13 }

You need to ensure that when a new version of the application is available, it is automatically installed and the user is notified.
Which code segment should you insert at line 11?

You are developing a Silverlight 4 application. You define the visual behavior of a custom control in the ControlTemplate by defining a VisualState object named Selected. You need to change the visual state of the custom control to the selected state. Which code segment or XAML fragment should you use?

You are developing a Silverlight 4 application. The Web page of the application contains a Text Box that has the txtTime ID. You define the following JavaScript function on the Web page.
function ShowTime(strTime) {
document.getElementById(‘txtTime’).value = strTime;
}
You need to pass the current time to the ShowTime function from Silverlight. Which code segment should you use?

You are developing a ticketing application by using Silverlight 4.
You have a listbox named lstTickets that contains a list of the tickets. The page contains a button that allows the user to print the tickets. The PrintView UserControl binds to the type in lstTickets and is designed to fit a standard sheet of paper. You add the following code segment to the button event handler. (Line numbers are included for reference only.)

01 var doc = new PrintDocument();
02 var view = new PrintView();
03 doc.PrintPage += (s, args) =>
04 {
05 var ppc = doc.PrintedPageCount;
06 if (ppc < lstTickets.Items.Count)
07 {
08 var data = lstTickets.Items[ppc];
09 view.DataContext = data;
10 args.PageVisual = view;
11
12
13 }
14 };
15 doc.Print(“tickets”);

You need to use the Silverlight printing API to print each ticket on its own page. You also need to ensure that all tickets in the listbox are printed.
Which code segment should you insert at lines 11 and 12?

You are developing an application by using Silverlight 4 and Microsoft .NET Framework 4.
You add the following code segment. (Line numbers are included for reference only.)

01 public class MyControl : Control
02 {
03
04 public string Title
05 {
06 get { return (string)GetValue(TitleProperty); }
07 set { SetValue(TitleProperty, value); }
08 }
09 }

You need to create a dependency property named TitleProperty that allows developers to set the Title. You also need to ensure that the default value of the TitleProperty
dependency property is set to Untitled. Which code segment you add at line 03?
