Yes, you certainly could write a MapBasic program. We started that a while
back and ended up investing five man years in the Images+ product. But you
are on the right track with the overall concept.
Opening the tables is relatively simple in MapBasic. The hard part come
when you want to make lots of mappers, document them, add thematics, set
map projections and open everything robustly. And sometimes we want to
create a new mapper but at other times we just want to change the later
attributes or add and remove layers from the current mapper.
Our solution was to add a "save" button to MaInfo that interrogates a
mapper, saves the mapper definition into a database, and gives it a unique
database ID. On the way through we catalogue the individual table files so
we can reference them by ID rather than less robust file systems location
(we gave up on MapInfo workspaces as customers needed something more
reliable that did not break when you moved a file - especially in our
geology work where 20 to 50 map layers in quite common).
We built a catalogue browse interface to manage and document the mappers
and browsers and another tool that lets you pick a window definition (or
group or definitions) from the database interface and hot-link them to any
MapInfo map object.
When you click on the object we look through the MapInfo attributes to find
the database ID, look up the database, and then invoke the required
actions. In your case we would open a mapper, but commonly we open a word
file, an external database form or invoke some other external process, that
make use of the MapInfo attribute values or location of the clicked object. .
Like you, we thought it was going to be a simple MapBasic program � but
have ended up using MapBasic, VB, C++ and OLE. But the good news is you can
licence it from your local GeoBasemap reseller for a very modest fee.
