Hi!
What you meant '...to check many considerations and user response'? Middle-tire COM object works just in the request-response way and it is stateless, so what checking you need? Just query data and send it.
Look to West Wind site for Rick's articlles about XML and SOAP. Look to his classes (wwXML, wwSOAP). They help to organize communication between tires using XML, that guarantee correct data transfer.

> However, I am wondering that, how will the COM object (middle tier) being designed since it need to check many considerations and user response?
> Any body can provide me a simple sample code for it?

The professional level of programmer could be determined by level of stupidity of his/her bugs
It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
