Guy,

Yours is the only feedback I've received on this even though I put it up here and News Groups and List Servers.

I like the code-behind and will for now use it as front end code, and have it call any business rules, that middle tier then will call any data needs.

Since it compiles with the page I don't think it should be used for middle tier code.

Thanks,
Terry
