The OnError event is generated when an error occurs while
          the component is performing an operation. Visual Basic errors do not
          generate this event.
          The ErrorCode argument specifies the last error that has
          occurred. If the error is network related, the error code values
          returned by the component correspond to those returned by the
          standard Windows Sockets library.
          The Description argument is a string that describes the
          error. This corresponds to the LastErrorString property.
