An unhandled exception of type 'System.InvalidOperationException' occurred in system.data.dll

Additional information: Update unable to find TableMapping['Table'] or DataTable 'Table'.

To resolve this problem, make sure that the DataTable that you want to update is not Nothing or Null before you pass it into the Update method of the DataAdapter.

It looks like you're trying to pass an Update to an empty Dataset you've just created.
You need to fill the dataset with information:

Something like:
Da.Fill(DS);
