Creating an ADO recordset in C++

I need sample code to show me how to build my own ADO recordset in VC++.  So, I need to create a blank recordset, append field names, open the blank recordset without having a live connection, add new values to the fields I created, and then update the recordset.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
