>I need to scan all the fields in a dataset. I am assuming a For\Each syntax would apply. What would be the simplest way to do that?

I doubt that you need me to come up with this, but this at least compiles alright :)

    Sub Main()
        Dim ds As New DataSet
        For Each dt As DataTable In ds.Tables
            For Each dc As DataColumn In dt.Columns

            Next
        Next
    End Sub
