>Resolving loRow repeatedly in that last line looks a bit slow. Why not:

Dim rows as DataRowCollection = oDataProvider.oDataSet.Tables("Temp").Rows
>For lnCounter2 = lnStart To lnMax - 1
>       loRow = rows(lnCounter2)

Come to that why not allow a flexible batch size.Something like:

Public Sub ProcessAll(ByVal lnBatchSize As Integer)
>        Dim i As Integer = 0
>        Dim lnCount As Integer = oDataSet.Tables("Temp").Rows.Count
>        While i < lnCount - lnBatchSize
>            ProcessBatch(i, i + lnBatchSize - 1)
>            i += lnBatchSize
>        End While
>        ProcessBatch(i, lnCount)
>    End Sub
>    Public Sub ProcessBatch(ByVal first As Integer, ByVal last As Integer)
>        Dim loRow As DataRow
>        Dim rows As DataRowCollection = oDataSet.Tables("Temp").Rows
>        For lnCounter2 As Integer = first To last
>            loRow = rows(lnCounter2)
>        Next
>    End Sub

For its use so far, it was not an impact. But, doing it on a large scale dataset, then, the idea sounds good. I will have to check it out. Thanks for the info.

The idea about allowing the class to exposure a property for the number of items to be processed in the batch sounds good. I will make it to default to 1000.

Thanks
