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:Naitie= "styleItalic"
TargetType="{x:Type Button}">
<Setter Property="FontStyle" Value="Italic"/></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 = this.FindName("styleltalic") as Style;
• B. button1.Style = this.FindName("btnltalic") as Style;
• C. button1.Style = this.FindResource("styleltalic") as Style;
• D. button1.Style = this.FindResoucce("btnltalic") as Style;

You are developing a Windows Presentation Foundation (WPF) application. You have a class named Orders, which contains OrderId and ShipOn properties. You place a control in the MainWindow.xaml file, as follows. (Line numbers are included for reference only.)

When you run the application, the ComboBox control displays the class name for every row.
You need to ensure that the ComboBox control displays the Orderld and ShipOn values in columns.
Which markup segment should you add at line 03?

• A. <ItemsControlTemplate>
  <Datatemplate>
  <Grid>
  <TextB1ock Text="{Binding OrderId}"/>
  <TextB1ock Text="{Bindmg ShipOn}"/>
  </Grid>
  </DataTemplate>
  </ItemsControl.ItemTemplate>
• B. <ItemsControl.ItemTemplate>
  <BataTemplate>
  <Grid>
  <Grid.ColumnDefinitions>
  <ColumnDefinition />
  <CoIumnDefinltion />
  </Grid.CoIumnDefinitions>
  <TexcBlock Grid.Column""0" Text-"{Binding OrderId}"/>
  <TextB1ock Grid.Column="1" Text= Text="{Binding ShipOn}"/>
  </Grid>
  </DataTemplate>
  </ItemsControl.ItemTemplate>
• C. <ItemsControl.ItemsPanel>
  <ItemsPanelTemplate>
  <Grid>
  <TextB1ock Text="{Binding OrderId}"/>
  <TextB1ock Text="{Binding ShipOn}"/>
  </Grid>
  </ItemsPanelTemplate>
  </ItemsControl.ItemsPanel>
• D. <ItemsControl.ItemsPanel>
  <ItemsPanelTemplate>
  <Grid>
  <Grid.ColumnDefinltions>
  <ColumnDefinition />
  <ColumnDefinition />
  </Grid.ColunmDefinitions>
  <TextBlock Grid.Column="0" Text="{Binding OrderId}"/>
  <TextBlock Grid.Column="1" Text="{Binding ShipOn}"/>
  </Grid>
  </IcemsPanelTemplate>
  </ItemsControl.ItemsPanel>

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

You use Microsoft .NET Framework 4 to create a Windows Presentation Framework (WPF) application.
You plan to create a custom control that contains four text input fields. Each of the text input fields within the control will contain a label.
You need to ensure that the text input fields within the control can be validated by using a regular expression validator.
Which class should you inherit from?

• A. UIElement
• B. TextElement
• C. TextBox
• D. UserControl

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 <Canvas>
02 <Rectangle Stroke-"Red" StrokeThickness-"5" Height-"60"
03 Width-"60" Canvas. Left100" Canvas.Top-"100"> 04
05 </Rectangle>
06 </Canvas>
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. <Rectangle.RenderTransform>
  <RotateTransform Angle="45" CenterX="100" CenterY="100"
  /></Reccangle.RenderTransform>
• B. <Rectangle.RenderTransf orin>
  <RotateTransform Angle="45" CenterX="0" CenterY="0" />
  </Rectangle.RenderTransform>
• C. <Rectangle.LayoutTransform>
  <RotateTransform Angle="45" CenterX-"0M CenterY="0"/>
  </Rectangle.LayoutTransform>
• D. <Rectangle.LayoutTransform>
  <RotateTransforro Angle="45" CenterX="100"
  CenterY="100'7></Rectangle.LayoutTransform>
