You are developing a Windows Presentation Foundation (WPF) application.
Two styles, Blue and Green, are used for Border objects. The two styles have the same values for the CornerRadius and BrushThickness properties and different values for the Background property.
You need to define the CornerRadius and BrushThickness settings in either the Blue or the Green style, but not both.
What should you do?

• A. Separate Blue and Green into two files. Put the base settings in Blue and use MergedDictionaries. Ensure that the Blue file is second in the list.
• B. Put Blue and Green into the same file. Put the base settings in Blue and mark Blue as BasedOn Green.
• C. Separate Blue and Green into two files. Put the base settings in Blue and use MergedDictionaries. Ensure that the Green file is second in the list.
• D. Put Blue and Green into the same file. Put the base settings in Blue and mark Green as BasedOn Blue.

You use Microsoft -NET Framework 4 to create a Windows Forms application.
You have a form named Forml that has a TableLayoutPanel control named tableLayoutPanel1. tableLayoutPanel1 has two rows and two columns.
You need to create a method that meets the following requirements:
Accepts a string parameter Dynamically creates a Label control that appears in the first column Dynamically creates a TextBox control that appears directly below the Label control

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

You are developing a Windows Presentation Foundation (WPF) application.
Users can enter formatted percentages into text boxes.
The markup is as follows.
<TextBox Text="{Binding Path=Percentage,
Converters StaticResource PercentValueConverter}}" />
Percentage is a decimal property.
You need to store the percentages as their decimal values, not their display values.
Which code segment should you use?

• A. Public Function Convert (
  ByVal value As Object, ByVal targetType As Type,
  ByVal parameter As Object, ByVal culture As CultureInfo)
  As Object
  Return CDec (parameter) .ToStrmg ("P")
  End Function
• B. Public Function Convert (
  ByVal value As Object, ByVal targetType As Type,
  ByVal parameter As Object, ByVal culture As CultureInfo)
  As Object
  Return CDec(value).ToString("P")
  End Function
• C. Public Function ConvertBack{
  ByVal value As Object, ByVal targetType As Type,
  ByVai parameter As Object, ByVal culture As CultureInfo)
  As Object
  Return (Decimal.Parse(value.ToString()) / 100)
  End Function
• D. Public Function ConvertBack(
  ByVal value As Object, ByVal targetType As Type,
  ByVal parameter As Cliiert, ByVal culture As cultureInfo)
  As Object
  Return (Decimal.Parse (parameter.ToString ()) / 100)
  End Function
