Hi all,

I fill my datagrid using this code :
Private Sub LoadData()
        'Construct data adapter
        SelectCmdString = "select * from SMSQUEUE WHERE Acknowledged=0 order by SMSQueueID"
        da = New SqlDataAdapter(SelectCmdString, conn)
        da.Fill(ds, "SMSQUEUE")
        LabelID.DataBindings.Add("Text", ds, "SMSQUEUE.smsqueueid")
        LabelDate.DataBindings.Add("Text", ds, "SMSQUEUE.createdon")
        LabelDestination.DataBindings.Add("Text", ds, "SMSQUEUE.destination")
        LabelDescription.DataBindings.Add("Text", ds, "SMSQUEUE.description")
        DataGrid1.SetDataBinding(ds, "SMSQUEUE")
        Timer1.Interval = CInt(myInterval) * 1000
        Timer1.Enabled = True

    End Sub

This gives a Datagrid with 13 columns
I only want the 8th column to be editable(boolean, so just click on/off)
If the checkin this row has been changed, I need to update the 1st and 5th column with a timestamp and the user that performed the update.
I also need to be able to do this in batch.

Now, I am saving changes to other columns in batch like this :

SelectCmdString = "select * from SMSQUEUE WHERE Acknowledged=0 order by SMSQueueID"
        Dim strUser As String = UCase(InputBox("Your Login Name?", "Security"))
        If Verify_user_Settings(PrivGroup, DomController, strUser) Then
            If ds.HasChanges() Then
                Dim da As SqlDataAdapter
                Dim command_builder As SqlCommandBuilder
                 da = New SqlDataAdapter(SelectCmdString, conn)
                da.TableMappings.Add("Table", "SMSQUEUE")
                 command_builder = New SqlCommandBuilder(da)
                 da.Update(ds)
                MsgBox("Changes have been Committed")
            End If
        Else
            MsgBox("Group Security Policies denies you changing data.")
        End If

Any suggestions ?
I HATE ADO.NET !!!! Things I always found easy are sudenly hard to do...... GRRRRRRR!!!!!!!
