Connecting Crystal Reports using OLEDB

I have a native driver ( thin client ) in the domino server machine for connecting MS SQL. I want to connect to a crystal report file using the thin client in browser through OLEDB. Can somebody provide me a sample code?

Note : I am successful in connecting crystal report using ODBC DSN in web but I am interested in doing the same through OLEDB method without using ODBC DSN.

Help in this regard will be appreciated.
