A user control responds to a click event. The click event handler sets the Handled property to True.
You need to ensure that a parent control responds to the event after the user control's handler executes.
What should you do?

• A. Programmatically add an event handler to the parent control and set the HandledEventsToo property to False.
• B. Programmatically add an event handler to the parent control and set the HandledEventsToo property to True.
• C. Add a tunneling routed event handler to the parent control.
• D. Add a bubbling routed event handler to the parent control.

You are develping a Windows Presentation Foundation (WPF) application.
You plan to deploy the WPF application by using ClickOnce. The application will be associated to files that have an extension of .abc.
You need to ensure that when a user opens the application by double-clicking an .abc file, a TextBlock named txtBlockl displays the path of the file.
Which code should you use?

• A. txttBlock1.Text = App.Current.Properties["ActivationData"].ToString();
• B. txtBlock1.Text = DataContext .ToString ();
• C. txttBlock1.Text = App.Current.Properties["FilePath"].ToString();
• D. txtBlock1.Text = AppDomain. CurrentDomain.Setup Information. ActivationArguments. ActivationData \0\ .ToString ();

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application contains an ObservableCollection object named Pictures that contains several Picture objects. Each Picture object contains the Name and PictureFilePath properties.
You add a ListBox control to the application.
You need to ensure that the pictures are displayed in the ListBox control.
Which code fragment should you use?

• A. <ListBox ItemsSource="{Binding Source={StaticResource pictures}}">
  <ListBox. ItemTemplate>
  <DataTemplace>
  <Image Source="{Binding Source={StaticResource pictures},
  Path=PictureFilePath)"/></DataTemplate>
  </ListBox.ItemTemplate>
  </ListBox>
• B. <ListBox ItemsSource="{Binding Source={StaticResource
  pictures))"><ListBox.ItemTemplate>
  <DataTemplate>
  <Image Source-"{Binding Path PictureFilePath>"/>
  </DataTemplate>
  </ListBox.ItemTemplate>
  </ListBox>
• C. <ListBox ItemsSource="{Binding Source={StaticResource pictures}>">
  <ListBox.ItemTemplate>
  <DataTemplate>
  <TextBlockxTextBlock.Text>
  <Binding Path="Name" />
  </TextBlock.TextX/TextBlock>
  </DataTemplate>
  </ListBox.ItemTemplate>
  </ListBox>
• D. <ListBox ItemsSource="{Binding Source={StaticResource
  pictures}}"><ListBox.Item>Template><DataTernplate>
  <TextBlock>
  <TextBlock.Text>
  <Binding Path="PictureFilePath" />
  </TextBlock.TextX/TextBlock>
  </DataTemplate>
  </ListBox. ItemTeioplate>
  </LiscBox>

You use Microsoft. NET Framework 4 to create a custom Windows Presentation Foundation (WPF) application.
Your environment includes several WPF applications. The applications use the same logo and style configuration as part of a corporate standard.
You need to ensure that the existing applications can be updated to use the same logo and style settings without recompiling.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Use Resource Manager to read the content of the resource. Manually assign the style configurations included in the resource file to the appropriate control in each application.
• B. Create a resource in a custom control that contains the logo and style configurations.
• C. Create a resource in an XAML file that contains the logo and style configurations.
• D. Add the resource as a Resource Dictionary in the Merged Dictionaries collection of each application.
• E. Mark the resource as an embedded resource in each application.
