virtual IMessage^ Invoke( IMessage^ myMessage ) override
{
   IMethodCallMessage^ myCallMessage = dynamic_cast<IMethodCallMessage^>(myMessage);

   IMethodReturnMessage^ myIMethodReturnMessage =
      RemotingServices::ExecuteMessage( myMarshalByRefObject, myCallMessage );
   if ( myIMethodReturnMessage->Exception != nullptr )
   {
      Console::WriteLine( "{0} raised an exception.",
         myIMethodReturnMessage->MethodName );
   }
   else
   {
      Console::WriteLine(  "{0} does not raise an exception.",
         myIMethodReturnMessage->MethodName );
   }

   return myIMethodReturnMessage;
}

public override IMessage Invoke(IMessage myMessage)
{
   IMethodCallMessage myCallMessage = (IMethodCallMessage)myMessage;

   IMethodReturnMessage myIMethodReturnMessage =
      RemotingServices.ExecuteMessage(myMarshalByRefObject,myCallMessage);
   if(myIMethodReturnMessage.Exception != null)
      Console.WriteLine(myIMethodReturnMessage.MethodName +
         " raised an exception.");
   else
      Console.WriteLine(myIMethodReturnMessage.MethodName +
         " does not raised an exception.");

   return myIMethodReturnMessage;
}

Public Overrides Function Invoke(myMessage As IMessage) As IMessage
