You are converting a Windows Forms application to a Windows Presentation Foundation (WPF) application.
You use Microsoft .NET Framework 3.5 to create the WPF application.
The WPF application will reuse 30 forms of the Windows Forms application. The WPF application contains the following class definition.
public class OwnerWindow : System.Windows.Forms.IWin32Window
{
private IntPtr handle_Renamed;
public IntPtr Handle
{
get { return handle_Renamed ; }
set { handle_Renamed = value ; }
}
}
You write the following code segment in the WPF application.
(Line numbers are included for reference only.)
01 public System.Windows.Forms.DialogResult LaunchWindowsFormsDialog
(System.Windows.Forms.Form dialog, Window wpfParent)
02 {
03 System.Windows.Interop.WindowInteropHelper helper = new
System.Windows.Interop.WindowInteropHelper(wpfParent) ;
04 OwnerWindow owner = new OwnerWindow() ;
05
06 }
You need to ensure that the application can launch the reusable forms as modal dialogs.
Which code segment should you insert at line 05?

You are creating a Windows Presentation Foundation application. You create a window for the application.
The application contains an audio file named AudioFileToPlay.wav.
You need to ensure that the following requirements are met:
The audio file is played each time you click the client area of the window.
The window provides optimal performance when the audio file is being played.
What should you do?

You deploy a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
Users use Microsoft Windows Internet Explorer to launch the application. The application uses an XML file to persist user information. The XML file is used by multiple assemblies within the application. The company
security policy requires that each user has a separate copy of the XML file. During testing, you discover that the application can persist information to the XML file on the development computer but not on the client
computers. You need to ensure that the application can persist information to the XML file on all the client computers. You also need to ensure that the application maintains the required security level.
