Hi, Mike,
You should still be able to.
Let's say you designed the datatable for DtCustomers in the VS designer, as part of a DataSet (let's call it DsLocalTables).
Going back to my example, you'd use the object reference when you create an instance of the datatable...
MyLocalData.DtCustomers = new DsLocalTables.DtCustomersDataTable();
And then everything after that should be the same.
When you type "DsLocalTables.", Intellisense should show the list of data tables for the dataset that you designed. Note that .NET puts 'DataTable' at the end of whatever tablename you provided in the designer (at least it does for me).
Hope this helps...
Kevin
