You are creating a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
You plan to use the application to preview video files. You write the following XAML code fragment.

01 <Window x:Class="myClass" xmlns= "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="myWindow" Height="300" Width="300">
02 <StackPanel Background="Black">
03
04 <StackPanel HorizontalAlignment="Center" Orientation="Horizontal">
05 <Button Name="btnPlay" Margin="10" Content="Play" />
06 </StackPanel>
07
08 </StackPanel>
09 </Window>

You need to ensure that the application plays only the first 10 seconds of a video that you want to preview.

You are creating a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
You add a window that displays a Button control. You need to ensure that the Button control displays an ellipse that occupies the entire button control area.
Which code fragment should you use?

You are creating a Windows Presentation Foundation (WPF) application by using Microsoft .NET Framework 3.5.
The application contains a window that programatically displays an image. The window contains a Grid control named theGrid. You write the following code segment.
(Line numbers are included for reference only.)

01 Image theImage = new Image();
02 theImage.Width = 200;
03 BitmapImage theBitmapImage = new BitmapImage();
04 theBitmapImage.BeginInit();
05 theBitmapImage.UriSource = new Uri("imageToDisplay.jpg");
06 theBitmapImage.DecodePixelWidth = 200;
07 theBitmapImage.EndInit();
08
09 theGrid.Children.Add(theImage);

You need to crop an elliptical region of the image such that the ellipse is centered at the location X=75 and Y=50.
Which code segment should you insert at line 08?

You are creating a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
The application has a window that programatically displays an image. The window contains a grid named theGrid. The window displays images in their actual size. You want the images to be 200 pixels wide. You write the following code segment.

01 Image theImage = new Image();
02 theImage.Width = 200;
03 BitmapImage theBitmapImage = new BitmapImage();
04
05 theImage.Source = theBitmapImage;
06 theGrid.Children.Add(theImage);

You need to ensure that the application meets the following requirements:

* The window uses the least amount of memory to display the image.
* The image is not skewed.

* The graphic and the descriptive text appear as a sidebar at the beginning of the document.
* The exact placement of the sidebar is not critical.
* The existing document text flows around the graphic and descriptive text.
* The descriptive text is not truncated.

You are creating a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
You include functionality in the application to troubleshoot the window behavior.
You need to display a list of UI elements at a position in the window that is decided by the mouse click. You also need to ensure that the list of elements is displayed in a message box.
Which code segment should you include in the code-behind file?

You are creating a partial trust XAML Browser Application (XBAP) in Windows Presentation Foundation by using Microsoft .NET Framework 3.5.
The application needs to display an image named Forest.jpg. The image can be replaced without rebuilding the application. You need to ensure that the application correctly references the image.
Which code fragment should you use?

You are creating a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
The application-definition file contains the following XAML code fragment.

<Application.Resources>
<Style x:Key="ContentControlStyle">
<Setter Property="ContentControl.Background" Value="Magenta" />
</Style>
</Application.Resources>
You add a window to the application. The window definition includes the following XAML code fragment.

<Window.Style>
<Style>
<Setter Property="Button.Background" Value="Green" />
</Style>
</Window.Style>
<Button Content="Open" Background="Yellow" >
<Button.Style>
