I should have stated more clearly that I'm using a typed dataset (you can see it in my code, but I didn't mention it explictly).

That's why I'm working so hard to use FillDataSet. I'm still stuck on the fact that there is no overload for FillDataSet that just takes one dataset parameter.

In addition to the dataset, FillDataSet also wants an IDbCommand or string (SQL statement), which is what seems redundant, given that the SqlDataAdapter in my custom data access class already has the IDbCommand and TableMappings it needs (in the SelectCommand member) to fill the dataset.
