how To pass an array of userdefined type from VB to Oracle stored procedure

Hi All...
how To pass an array of userdefined type from VB to Oracle stored procedure.

Thanks

As far as I've been able to determine from experience and reading around on the web, you can't.

<hint>Although I'd love to eat crow on this one if they can show how to do so with any Oracle ADO provider.</hint>

but if not user defined sets .. is it possible to pass in just the DB recordsets into an oracle SP.
