Check if DataAdapter holds rows

Hi EE,

I am trying to figure out how to tell if a dataadapter has rows.  I know how to do it with a datareader, but haven't been able to figure out how with a dataadapter.
Please provide an example.  Clicking on links crash my IE.
Below is the code I use to fill the dataadapter.
Dim ds As New DataSet
        If DatabaseToUse() = BizObjs.DBType.Access Then
            'Access Database
            Dim dc As New OleDb.OleDbConnection(ConnectionString)
            Dim da As New OleDb.OleDbDataAdapter(SelectStatement, dc)
            Catch ex As Exception
                'Throw ex
            End Try
        End If
        Return GenerateDataTable(ds)

You can use ds.tables(0).rows.count.
if ds.tables(0).rows.count>0 then

 ' Block Of Code

End If

Please let me know if I am not following your question correctly.

How does the dataset know what is in there since the fill will go after the "if ds.tables(0).rows.count>0 then".  There is no other reference to the dataset until then?
Where are you getting the exception in your code? I am guessing it is not when you fill the dataset. You need to check for the row count before you use the dataset( You need to fill the dataset and then check for row count before using it).

I was getting the error right on the da.fill(ds).  I just tried again and I no longer get the error.  Not sure what is going on, but thanks for your help
