re: "I remember running across when I did this is that I when I sub-classed my Typed DataSet it was *not* marked as serializeable and that caused problems until I changed it."

Bonnie, that is indeed the case here. I just got word from Kevin that in the version of MM.NET that I am using the mmDataSet class is not marked [Serializable()]. He is taking care of this (talk about good tech support!).

Thanks, Bonnie, for your assistance.

So, are you ready for NBC's "10.5 Earthquake" movie? <g> I think they have you folks sliding into the Pacific...
