I DataSet can have more than one table so you need to iterate the collection of tables and see if any have any rows in them like this:

    Private Function hasRecords(ByVal ds As DataSet) As Boolean
        If Not (ds Is Nothing) Then
            Dim dtCol As System.Data.DataTableCollection = ds.Tables
            If dtCol.Count > 0 Then
                Dim dt As DataTable
                For Each dt In dtCol
                    If dt.Rows.Count > 0 Then
                        Return True
                    End If
                Next
                Return False
            Else
                Return False
            End If
        Else
            Return False
        End If
    End Function
