peter,
Please don't crosspost to so many groups. You've definitely hit some
unrelated groups. For example, this group: .data.ado. as well as the vstudio
groups, I suspect (I may be wrong about that however. I think the vsnet
groups may be more apprpriate, but maybe the people in the vstudio groups
handle .Net questions as well ... )

Here is my canned reply which shold be ignored in the groups where this
question is relevant:
There was no way for you to know it (except maybe by browsing through some
of the previous questions before posting yours - always a recommended
practice) , but this is a classic ADO newsgroup. ADO.Net bears very little
resemblance to classic ADO so,
while you may be lucky enough to find a dotnet-knowledgeable person here who
can answer your question, you can eliminate the luck factor by posting your
question to a group where those dotnet-knowledgeable people hang out. I
suggest microsoft.public.dotnet.framework.adonet.
.... or even one of the vsnet groups.
