DB/Reporting :: DataTable Updates To Database ?

I have one specific problem, that is relative to DataTable Updates to Database.

Code:

auxDatatable = Mydataset.MyDatatable.GetChanges

Now i'm going to Accept or Reject Changes based on some Criteria. The problem is that I wish to Update Only the Records that in Fact exist on the Database, as you can imagine I was forced to create some Dummy Records in Datatable, to a specific job.

My approach to this issue was to do something like this :

Code:

Private Sub MySub (ByVal auxDatatable As DataTable)

Dim drView As Mydataset.Mydatatable

For i As Integer = 0 To auxDatatable.Rows.Count - 1

[CODE]...

As you can see I tried to Delete the rows that are Dummys, but the rows in fact are not being deleted. As consequence I get an error after that Sub, when i try to make :

Code:

MyTableAdapter.Update(auxDatatable)

This is naturaly caused by the dummy Records.
