I have posted this on C# group but got no response.

First time application with databases.   I am missing the point where it
actually updates the database table.  I am only updating a single table,  
this more or less directly from 'how to: save changes from a dataset to a
database' in MSDN.

I am totally lost and stuck.  What should I check?

Help

I am trying to get the database to update on change of a combobox Match.  
The table is tblMatch and I have a simple textbox defined with:

TextBox  - databindings - text: tblMatchBindingSource - Description

The description appears but the following does not write back the changes:

      private void Match_SelectedIndexChanged(object sender, EventArgs e)
       {
           Validate();
           tblMatchBindingSource.EndEdit();
           tblMatchTableAdapter.Update(AccessDBDataSet.tblMatch);

How do I commit the changes to the database.

Thanks
Ken
