You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You write the following code fragment.
< StackPanel TextBox.PreviewTextInput="StackPanel_PreviewTextInput" >
< TextBox Name="TxtBoxA"/>
< TextBox Naroe="TxtBoxB"/>
< TextBox Name="TxtBoxC"/>
< /StackPanel>
You create an event handler named StackPanel_PreviewTextInput. You also have a collection of strings named Keywords.
You need to ensure that TxtBoxA and TxtBoxB do not contain any of the strings in the Keywords collections.
Which code segment should you use?

• A. Handled = true; return; )
  }
• B. Handledfalse;
  return;
  }
  }
• C. Handled = true; return;
  }
  }
• D. Handled = true;
  } }
• E. Handled = true;
  }
  }
• F. Handled = false; return;
  }
  }

  object sender, TextCompositionEventArgs e)
  (
  FrameworkElement feSource = e.Source as FrameworkElement; if
  (feSource.Name == "TxtBoxA" || feSource.Name == "TxtBoxB")
  {
  foreach(string keyword in Keywords)
  {
  if(e.Text.Contains(keyword))

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application contains a custom control that is used to display customer Information.
You discover that the custom control is not rendering correctly.
You need to identify the WPF element that is causing the issue.
What should you do?

• A. Enable IntelliTrace and configure Visual Studio to generate a trace log.
  Start the application by double-clicking the executable file (.exe).
• B. Start the application in debug mode.
  Place a breakpoint at the main entry point of the application.
  Use the WPF Tree Visualizer tool.
• C. Enable IntelliTrace and configure Visual Studio to generate a trace log.
  Start the application in debug mode.
• D. Start the application in release mode.
  Place a breakpoint at the main entry point of the application.
  Use the debugger to step through the application code.

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You want to localize the application to use the German locale settings.
