• Question 184:

  You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. You want to add an audio player that plays .wav or .mp3 files when the user clicks a button. You plan to store the name of the file to a variable named SoundFilePath.

  You need to ensure that when a user clicks the button, the file provided by SoundFilePath plays.

  What should you do?

  A. Write the following code segment in the button onclick event. System.Media.SoundPlayer player = new System.Media.SoundPlayer(SoundFilePath); player.Play() ;
  B. Write the following code segment in the button onclick event. MediaPlayer player = new MediaPlayer() ; player.Open(new URI(SoundFilePath), UriKind.Relative)); player.Play() ;
  C. Use the following code segment from the PlaySound() Win32 API function and call the PlaySound function in the button onclick event. [sysimport (dll="winmm.dll") ] public static extern long PlaySound(String SoundFilePath, long hModule, long dwFlags);
  D. Reference the Microsoft.DirectX Dynamic Link Libraries. Use the following code segment in the button onclick event. Audio song = new Song(SoundFilePath); song.CurrentPosition = song.Duration; song.Play ();

  B. Use UISpy.exe to extract the user interface (UI) Information. Then, use MSTest.exe.
  C. Use classes in the System.Windows.Automation and System.Windows.Automation.Text namespaces.
  D. Use the Action Recording methodology to record the user interface (UI) actions. Then, use MSTest.exe.
  C. Use classes in the System.Windows.Automation and System.Windows.Automation.Text namespaces.

• Question 186:

  You are developing a Windows Presentation Foundation (WPF) application. The application consists of:

  

  A window that contains controls organized into groups.

  

  Groups that are ordered vertically and that have individual headings.

  

  Controls within the groups that are ordered horizontally.

  

  Groups and controls that will be added dynamically at run time.

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

  

  The window must be resizable without affecting the layout of the controls.

  

  The controls within the groups must be laid out such that there is a minimum amount of spacing between groups.

  What should you do?

  A. Use a WrapPanel control to organize the groups with its Orientation property set to Vertical. Use WrapPanel controls to organize the controls with their Orientation property set to Horizontal.
