passing data between dlls

[mfoster]

I am trying to convert an app into using a more object orientated approach. I have created active x dlls to handle business rules etc on client machines.

I have also made an active x exe to handle all data access which will sit on one machine.

I am uncertain however as to the best way to pass groups of data from the client to the data server.

I was going to use Lset but I gather that this has been dropped from vb.net therefore perhaps it would be best to avoid it.

For a single record, I could use the property bag object but I'm not sure how to pass groups of records - eg a list of suppliers that would be used to fill a combo box for example

Many thanks for any help you can offer
