Visual Basic

Public Shared Sub Main()
    'Creates an exception with an error message.
    Dim myException As New
 Exception("This is an exception test")
       
    'Creates an ErrorEventArgs with the exception.
    Dim myErrorEventArgs As New
 ErrorEventArgs(myException)
       
    'Extracts the exception from the ErrorEventArgs and display it.
    Dim myReturnedException As Exception =
 myErrorEventArgs.GetException()
    MessageBox.Show("The returned exception is: "
 _
       + myReturnedException.Message)
End Sub

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);
}

C++

int main()
{
   
   //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.
    System.Exception myException = 
        new System.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.
    System.Exception myReturnedException = myErrorEventArgs.GetException();

    MessageBox.Show("The returned exception is: " 
        + myReturnedException.get_Message());
} //main
