Copy Datatable from one Dataset to another Dataset
Copying a datatable from one dataset to another was not that straightforward as I thought.
Dim dsSource As New DataSet Dim dsDestination As New DataSet 'Your way to get data from XML or DB. dsSource = object.getdata() dsDestination = object.getmoredata() 'This is important, without this it will result in error 'when you try to copy the datatable from one dataset to another dsSource.Tables(0).TableName = "NewTableName" dsDestination.Tables.Add(dsSource.Tables(0).Copy) dsDestination.Tables(0).Tablename = "SomeTable" dsDestination.Tables(1).Tablename = "NewTableName" 'The one we copied from other Dataset
Note 1 : When you are using more than one datatable in a dataset it is advisable you name the datatables.
Note 2 : These kinds of scenarios arise, when you are trying to establish Relation between datatables in a dataset.

Thanks for the lesson! I have a question though. If dsSource and dsDestination are from different databases, like a live DB and a test one, will calling dsDestination.AcceptChanges() then add the new table to its database?
