Microsoft TS: Windows Applications Development with Microsoft .NET Framework 4 : 070-511

You develop a Windows Presentation Foundation (WPF) application. The application runs
on 64-bit machines only.
The application architects want to store application settings in the registry. The users do not have write access to these settings. These application settings apply to everyone using the application.
You need to read the application settings successfully from the registry.
Which code segment should you use?

• A. RegistryKey
  *OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64)
  *OpenSubKey(@"Software\MyProgram")
  *GetValue("ConnectionString");
• B. RegiatryKey
  *OpenBaseKey(RegistryHive.LocalMachine. RegistryView.Registry64)
  *CreateSubKey(@"Software\MyProgram")
  *GetValue("ConnectionString") ;
• C. RegistryKey
  *OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64)
  *CreateSubKey(@"Software\MyProgram")
  *GetValue("ConnectionString");
• D. RegistryKey
  *OpenBaseKey{RegistryHive.LocalMachine, RegistryView.Registry64)
  *OpenSubKey(@"Sofware\MyProgram")
  *GetValue("ConnectionString") ;

The application contains a window as shown in the following exhibit.

You need to define a DockPanel control that fits the window. Which code fragment should you use?

• A. <DockPanel>
  <Button Content="Leftp7>
  <Button Content="Top" DockPanel.Dock="Top"/>
  <Button Content="Center">
  <Button Content="Bottom" DockPanel. Dock="Bottom">
  </DockPanel>
• B. <DockPanel>
  <Button Content="Left"/>
  <Button Content="Top" DockPanel.Dock="Top">
  <Button Content="Bottom" DockPanel.Dock="Bottom"/>
  <Button Content="Center"/>
  </DockPanel>
• C. <DockPanel>
  <Button Content="Top" DockPanel.Dock="Top"/>
  <Button Content="Left"/>
  <Button Content="Center'7>
  <Button Content="Bottoiti" DockPanel. Dock="Bottoinr7>
  </DockPanel>
• D. <DockPanel>
  <Button Content="Top" DockPanel.Dock="Top"/>
  <Button Content="Bottom" DockPanel. Dock="Bottom">
  <Button Content="Left"/>
  <Button Content="Center'7>
  </DockPanel>

You are developing a Windows Presentation Foundation (WPF) application.
You pull employee information from an XML file named EmployeeData.xml. The XML file is
as follows.

You need to display all the employee information from the XML file in EmployeeList.
Which markup segment should you use?

• A. <ListBox.Resources>
  <XmlDataProvider x:Key="FeedData" Source="EmployeeData.xml"
  XPath="/Employees/Employee"/>
  </ListBox.Resources>
• B. <Window. Resources>
  <XmlDataProvider x:Key="FeedDoca" Source="EmployeeData.xml"
  XPath="/Employees/Employee"/>
  </Window.Resources>
• C. <Window. Resources>
  <XmlDataProvider x:Key=FeedData" Source="EnployeeData.xml" XPath="/Employees" />
  </Window.Resources>
• D. <ListBox.Resources>
  <XmlDataProvider x:Key="FeedData" Source="EmployeeData.xml'' XPath="/Employees"
  />
  </ListBox.Resources>

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You add a TreeView control to show the hierarchical structure of orders and order details. Each order contains an ObservableCollection named OrderDetails.
You write the following code fragment. (Line numbers are included for reference only.)

---
You need to ensure that the TreeView control meets the following requirements:
Each order is shown as a TreeView node.
The order nodes have order detail nodes as children.
The order detail nodes have no children.
Which code fragment should you insert at line 07?

• A. <HierarchicalDataTemplate x:Key="OrderTemplate"
  ItemsSource="{Binding Path=orders}" DataType="Order">
  <TextBlock Text="{Binding Path=.}" />
  </HierarchicalDataTemplate>
• B. <HierarchicalDataTemplate x:Key="OrderTemplate"
  ItemsSource="{Binding Path=orders}"
  ItemTemplate="{StaticResource OrderDetailTemplate}">
  <TextBlock Text="{Binding Path=.}" />
  </HierarchicalDataTemplate>
• C. <HierarchicalDataTemplate x:Key="OrderTemplate"
  ItemsSource="{Binding Path=OrderDetails>"
  ItemTeinplate="{StaticResource OrderDetailTemplate} ">
  <TextBlock Text="{Binding Path=.}" />
  </HierarchicalDataTemplate>
• D. <HierarchicalDataTemplate x:Key="OrderTemplate" DataType="Order"
  ItemTernplate="{StaticResource OrderDetailTemplate} ">
  <TextBlock Text="{Binding Path=.}" />
  </HierarchicalDataTemplate>

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You plan to allow users to customize the background colors, foreground colors, and font style of the application. You also plan to add a TextBlock control to the application.
You write the following code fragment. (Line numbers are included for reference only.)

You need to ensure that the ContextMenu control is associated with the TextBlock control. You also need to ensure that the properties that can be customized are shown hierarchically.
Which code fragment should you insert at line 15?

• A. < Window.ContextMenu >
  < ContextMenu >
  < MenuItem Header="Color Scheme" DataContext="{StaticResource colorschemes)"
  ItemsSource="{ Binding Path ItemTemplate="{StaticRes ource StringTemplate}" />
  < MenuItern Header="Font" DataContext="{ StaticResource fonts!" ItemsSource=,,{
  Binding Path=.}" ItemTemplate="{StaticResource StringTemplate}" />
  < /ContextMenu >
  < /Window.ContextMenu >
• B. < Grid >
  <TextBlock Width="200" Height="100" Background="LightBlue" >
  < TextBlock.ContextMenu >
  < ContextMenu >
  < MenuItem Header="Color Scheme" DataContext="{StaticResource colorschemes)"
  ItemsSource="{Binding Path=.) ItemTemplate="{StaticResource ColorSchemeTemplate}" /
  >
  < MenuItem Header="Font" DataContext="{StaticResource fonts)" ItemsSource="{Binding
  Path=.}" ItemTemplate="{StaticResource StringTemplate}" >< /MenuItem >
  </ContextMenu >
  < /TextBlock.ContextMenu >
  < /TextBlock ></Grid >
• C. < Grid >
  < Menu >
  < MenuItem Header="Color Scheme" DataContext="{StaticResource colorschemes}"
  ItemsSource="{Binding Path=.}" ItemTemplate="{StaticResource StringTemplate}" / >
  < MenuItem Header="Font" DataContext="{StaticResource fonts}" ItemsSource="{Binding
  Path=.}" ItemTemplate="{StaticResource StringTemplate}" />
  < /Menu>
  < TextBlock width-"200" Height-"100" Background-"LightBlue" / ></Grid >
• D. < Grid >
  < TextBlock TJidth="200" Height= "100" Background="LightBlue" / ></Grid >
  < Window. ContextMenu >
  < ContextMenu>
  < TextBlock Width="200" Height="100" Background="LightBlue" / >
  < MenuItem Header="Color Scheme" DataContext="{StaticResource colorschemes}"
  ItemsSource="{Binding Path*.}" ItemTemplate="{StaticResource ColorSchemeTemplate}"
  />
  < MenuItem Header="Font" DataContext="{StaticResource fonts}" ItemsSource="{Binding
