   //Creates an exception with an error message.
   Exception^ myException = gcnew Exception( "This is an exception test" );
   
   //Creates an ErrorEventArgs with the exception.
   ErrorEventArgs^ myErrorEventArgs = gcnew ErrorEventArgs( myException );
   
   //Extracts the exception from the ErrorEventArgs and display it.
   Exception^ myReturnedException = myErrorEventArgs->GetException();
   MessageBox::Show( String::Concat( "The returned exception is: ", myReturnedException->Message ) );
}

public static void Main(string[] args) {
   //Creates an exception with an error message.
   Exception myException= new Exception("This is an exception test");

   //Creates an ErrorEventArgs with the exception.
   ErrorEventArgs myErrorEventArgs = new ErrorEventArgs(myException);

   //Extracts the exception from the ErrorEventArgs and display it.
   Exception myReturnedException = myErrorEventArgs.GetException();
   MessageBox.Show("The returned exception is: " + myReturnedException.Message);
}

Public Shared Sub Main()
    'Creates an exception with an error message.
    Dim myException As New Exception("This is an exception test")
