Microsoft 70-511 Online Questions & Answers

• Question 1:

  You are developing a Windows Presentation Foundation (WPF) application. A window is defined in the following markup segment.

  

  You need to add a Windows Forms Button control to the window programmatically.

  C. Dim wfButton As System.Windows.Controls.Button = New System.Windows.Controls.Button() wfButton.Content = "Button" grid1.Children.Add(wfButton)
  D. Dim host As WindowsFormsHost = New WindowsFormsHost() Dim wfButton As System.Windows.Controls.Button = New System.Windows.Controls.Button() wfButton.Content = "Button" grid1.Children.Add(wfButton)
  B. Dim host As WindowsFormsHost = New WindowsFormsHost() Dim wfButton As System.Windows.Forms.Button = New Systern.Windows.Forms.Button() wfButton.Text = "Button" host.Child = wfButton grid1.Children.Add(host)

• Question 2:

  You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application contains the following code fragment.

  Hello World Ok

  You need to define a style that applies the following properties to the text in the StackPanel object:

  

  FontSize = 32

  

  FontWeight = Bold

  Which code fragment should you use?

  B

• Question 3:

  You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. You write the following code fragment. (Line numbers are included for reference only.)

  01

  02

  03 Width-"60" Canvas. Leftoff Canvas.Top-"100"> 04

  05

  06

  You need to rotate the rectangle by 45 degrees by using its upper-left corner as the axis.

  Which code fragment should you insert at line 04?

  A

• Question 4:

  You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application uses the background worker process (BWP).

  When the user clicks a button, the background worker executes a method named DoCalculations asynchronously. You need to implement a progress bar on the user interface (UI) that Informs the user of the progress of DoCalculations.

  Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

  A. Modify the Value property of the progress bar in DoCalculations.
  B. Modify the Value property of the progress bar in the ProgressChanged event handler of the background worker.
  C. Modify the Value property of the progress bar in the RunWorkerCompleted event handler of the background worker.
  D. Call the ReportProgress method of the background worker in DoCalculations.
  E. Call the ReportProgress method of the background worker in the DoWork event handler of the background worker.
  B. Modify the Value property of the progress bar in the ProgressChanged event handler of the background worker.
  D. Call the ReportProgress method of the background worker in DoCalculations.

• Question 5:

  You are developing a Windows Presentation Foundation (WPF) application to play audio files. You add a MediaElement control named mediaElementl and a Button control named btnPlayAudio to the design surface. The MediaElement

  control Source attribute is set to an audio file. The LoadedBehavior attribute is set to Manual.

  You add the following code to the main window.

  Sub playCoinroand_Executed (ByVal sender As Object,

  ByVal e As RoutedEventArgs)

  MediaElenient 1.Play ()

  End Sub

  You set the command of the button to MediaCommands.Play.

  You need to ensure that the application will play the audio file when the button is pressed.

  What should you add to the constructor of the main window?

  A. Dim piayCommand As RoutedCommand = New RoutedCommand() AddHandler playCommand.CanExecuteChanged, New EventHandler(AddressOf playComrnand_Executed) Me.CommandBindings.Add(New CoinmandBinding (playCommand))
  B. Dim playCommand As RoutedUICommand = New RoutedUICommand() AddHandler playCommand.CanExecuteChanged, New EventHandler(AddressOf playCommand_Executed) Me . CommandBindings . Add (New CommandBinding (playCommand) )
  C. Dim playCommand As CoinmandBinding = New CommandBinding(MediaCommands.Play) AddHandler playCommand.CanExecute, New CanExecuteRoutedEventHandler( AddressOf playCommand_Executed) Me.CommandBindings.Add(playCommand)
  D. Dim playCommand As CoinmandBinding = New CoinmandBinding (MediaCommands.Play) AddHandler playCommand.Executed, New ExecutedRoutedEventHandler( AddressOf playCommand_Executed) Me.CommandBindings.Add(playCommand)
  D. Dim playCommand As CoinmandBinding = New CoinmandBinding (MediaCommands.Play) AddHandler playCommand.Executed, New ExecutedRoutedEventHandler( AddressOf playCommand_Executed) Me.CommandBindings.Add(playCommand)

• Question 6:

  App1 must be able to open files on local drives if the application is deployed from a file server.

  App1 must be prevented from opening files on local drives if the application is deployed from a Web server.

  Which file should you modify for each requirement? (To answer, drag the appropriate files to the correct requirements. Each file may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to
