If I have this code to get the data into a dataset:

            Dim loDT As New OleDbDataAdapter(tcSQL, _
             "Provider=VFPOLEDB.1;Data Source=" + tcTable + ";Password='';Collating Sequence=MACHINE")
            loDT.Fill(loData, "Temp")

How can I detect if loDT is in fact a dataset? Because, if the query returns no result, this will generate an error as soon as I try to make a reference to loDT.
