[Mapserver-users] ASP and MapServer

[Lowell Filak]

Unfortunately the index field must be in the dbf/database to provide a
link to the shape.
You could always take the original dbf and create a new dbf from it
which contains the index field or if your loading the data from the dbf
into something else you could populate the field as it is loaded.
