You are developing a Windows Presentation Foundation (WPF) application for a travel reservation system.
You need to ensure that users can select a range of travel dates.
What should you do?

• A. Add the appropriate Windows Forms references to the project references. Add a single windows Forms DoteTimePicker control to the design surface.
• B. Add a single MediaElement control to the design surface to display a calendar.
• C. Add a single Calendar control to the design surface.
• D. Add a single DatePicker control to the design surface.

You are developing a Windows Presentation Foundation (WPF) application. You have the following style defined in the app.xaml file.
<Style x:Key="btnItalic" x:Name="styIeItalic"
TargetType="{ x:Type Button}">
Setter Property="FontStyle" Value="Itallc"/></Style>
You need to apply this style to a button named button1 in the application at run time.
Which code segment should you use?

• A. button1.Style = TryCast(Me.FindName("btnItalic"), Style)
• B. button1.Style = TryCast(Me.FindResource("styleItalic"), Style)
• C. button1.Style = TryCast(Me.FindName("styleItalic"),Style)
• D. button1.Style = TryCast(Me.FindResource("btnItalic"), Style)

You are developing a Windows Presentation Foundation (WPF) application.
You are implementing the security features for a function that requires File 10. The callers of this function that are higher in the stack do not have permission to read the C:\temp directory.
The function also accesses other resources that require permission.
You need to ensure that the function has the proper permissions to read the C:\temp directory, and that all other resources in the function can still be accessed.
Which attribute should you include with the function?

• A. [FileIOPermissionAttribute(SecurityAction.PermitOnly, Read = "C:\\TEMP")]
• B. [FileIOPermissionAttribute(SecurityAction.Assert, Read = "C:\\TEMP")]
• C. [FileIOPermissionAttribute(SecurityAction.Demand, Read = "C:\\TEMP")]
• D. [FileIOPermissionAttribute(SecurityAction.InheritanceDemand,
  Read = "C:\\TEMP")]

You use Microsoft .NET Framework 4 to create a Windows Forms application.
You add a new class named Customer to the application. You select the Customer class to create a new object data source.
You add the following components to a Windows Form:
- A BindingSource component named customerBindingSource that is data-bound to the Customer object data source.
- A set of TextBox controls to display and edit the Customer object properties. Each TextBox control is data-bound to a property of the customerBindingSource component.
- An ErrorProvider component named errorProvider that validates the input values for each TextBox control.
You need to ensure that the input data for each TextBox control is automatically validated by using the ErrorProvider component.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Add the following code segment to the InitializeComponent method of the Windows
  Form.
  this.errorProvider.DataSource = this.customerBindingSource.DataSource;
  this.errorProvider.DataMember = this.customerBindingSource.DataMember;
• B. Implement the validation rules inside the Validating event handler of each TextBox
  control by throwing an exception when the value is invalid.
• C. Implement the validation rules inside the setter of each property of the Customer class
  by throwing an exception when the value is invalid.
• D. Add the following code segment to the InitializeComponent method of the Windows
  Form.
  this.errorProvider.DataSource = this.customerBindingSource;
• E. Implement the validation rules inside the TextChanged event handler of each TextBox
  control by throwing an exception when the value is invalid.

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

You need to implement the MyProject.AverageConverter class. What should you do?

• A. Apply the TypeConverterAttribute attribute
• B. Inherit from the TypeConverter class
• C. Implement the IValueConverter interface
• D. Implement the IMultiValueConverter interface
