Stonefield Database Toolkit (SDT) will handle this for you automatically. All you do is build our class libraries into your application, let SDT create some meta data tables for you, then ship the new EXE, DBC, and meta data tables to the client. Your application would instantiate one of our classes and call the Update method. Update will see that although the tables should be part of the DBC, in fact they're free tables, so it will automatically convert them to DBC tables (it even handles FoxPro 2.6 structures). It will also make any other structural changes required, such as adding or dropping fields, renaming fields, changing data types, etc.

For more information on SDT (it does a lot of other things like recreate corrupted indexes and repairing corrupted table and memo headers), check out Stonefield's Web site.
