Saving dataset changes with TableAdapter.Update(DataTable)

[dougancil]

I have a dataset that fills a tableadapter and I'd like to be able to post changes made to the dataset to a database with a date marking the changes. I've never used the TableAdapter.Update method before and was wondering if someone has any good tutorial links for that method.

Here is the code:

Imports System.Data.SqlClient
Imports System.Data
Public Class ExceptionEdit
    Private Sub ExceptionEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'MDRDataSet.scratchpad3' table. You can move, or remove it, as needed.
        Me.Scratchpad3TableAdapter.Fill(Me.MDRDataSet.scratchpad3)
        Exceptioncopy()
    End Sub
    Private Sub SaveExceptionButton(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles saveexceptionsButton.Click
        Try
            Me.Validate()
            Me.Scratchpad3BindingSource.EndEdit()
            Me.Scratchpad3TableAdapter.Update(Me.MDRDataSet.scratchpad3)
            MsgBox("Update successful")

        Catch ex As Exception
            MsgBox("Update failed")
        End Try
    End Sub

is it possible to update another database and not the scratchpad3 (since that's a temporary table and the actual table I need to update is a table called "Exceptions")

thank you

Doug

Hannes,
I looked at those and when I tried the code in what I've built so far, I get the error:

InvalidOperationException occured:
Update requires a valid UpdateCommand when passed DataRow collection with modified rows.

I've looked that error up and have seen a variety of answers. What I'm needing to do is to save the data back to another database and not the one that's filling the tableadapter. Is that possible?

[HanneSThEGreaT]

another ( totally different ) database, or another tabel ( within the same database ) ?

[dougancil]

Same database just another table. The table that is filling the table adapter is a temporary table ... and I want to update a table called Exceptions and not scratchpad3.

If you bind it to the actual table, it'd be easy to update. Use TEXT BOXES for the temporary record that the user sees. You can even fill it automatically for them.

[dougancil]

The table that I'm updating is "raw" data but the table that's filling in the table adapter is filtered with a stored procedure. So hence why I can't bind the table that I'm updating to the form.

Either use a SP to update the table.

If they don't go for that, don't use the SP's. This is .Net, not VB6
