Microsoft 70-511 Exam Questions : TS: Windows Applications Development with Microsoft .NET Framework 4

You are developing a user control for a Windows Presentation Foundation (WPF) application.
The user control contains a button. Both the user control and the hosting control must receive the button click event.
You need to ensure that the user control responds to the button click event before the hosting control responds to the event.
What should you do?

• A. Use a standard Microsoft .NET event. Set the Handled property to true.
• B. Use a bubbling routed event. In the button click event handler, set the Handled property to true,
• C. Use a tunneling routed event. Set the Handled property to false.
• D. Use a bubbling routed event. In the button click event handler, set the Handled property to false.

You are developing a Windows Presentation Foundation (WPF) application that displays opportunities from List (Of T) named Leads, where T is a class named Lead. The Lead class contains the properties Title and Revenue.
You add a DataGrid control named dgQualifiedLeads to the MainWindow.xaml file. You set the ItemSource property of dgQualifiedLeads to Leads as follows. (Line numbers are included for reference only.)

You need to ensure that CollectionViewSource is used to filter the list to display only Lead objects with revenue of more than $1,000.
What should you do?

• A. Insert the following code at line 22.
  Leads.Filter =
  New Predicate (Of Object)(AddressOf FilterOut)
  Add the following code segment to the code-behind of the MainWindow.xaml file.
  Public Function FilterOut(ByVal item As Object) As Boolean
  Dim lead As Lead TryCast(item, Lead)
  Return IIf(lead.Revenue > 1000D, False, True)
  End Function
• B. Insert the following code at line 22.
  Leads.Filter = New Predicate (Of Object)(AddressOf FilterOut)
  Add the following code segment to the code-behind of the MainWindow.xaml file.
  Public Function FilterOut(ByVal item As Object) As Boolean
  Dim lead As Lead = TryCast(item, Lead)
  Return IIf(lead.Revenue < 1000D, True, False)
  End Function
• C. Insert the following code at line 22.
  Leads.SortDescriptions.Add(New SortDescription(
  "Revenue", ListSortDirection.Ascending))
• D. Insert the following code at line 22.
  Leads.Filter =
  New Predicate(Of Object)(
  Function(s) DirectCast(s. Lead).Revenue > 1000D)

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. <FileIOPeritiissionAttribute ( SecurityAction.Demand, Read:="C:\TEMP")>
• C. <FileIOPermissionAttribute( SecurityAction.Assert, Read:= "C:\TEMP")>
• D. <FileIOPermissionAttribute(
  SecurityAction.InheritanceDemand, Read:="C:\TEMP")>

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

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You need to ensure that users can view content in a book-reading format that displays two pages at a time.
Which control should you use?

• A. FlowDocumentReader
• B. FlowDocumentScrollViewer
• C. FlowDocument
• D. FlowDocumentPageviewer
