Rick
I sympathise with your request. Actually, quite a few or our customers
maintain a table view of the coordinates, and update that view to match the
map locations after MapInfo editing. Or they want to drop points on a
mapper and print out the locations for surveying contractors and the like.
In our commercial GeoBasemap Mapping system product we have a module that
works as the reverse of the MapInfo create points item. It writes x/y back
into the MapInfo columns in the native projection of the table. Yes, you do
need to rerun the module each time you edit the map locations, but most
users find this quite workable.
For a more sophisticated solution, we comonly build custom applicaitons
that take over the point drawing function. We base these on the standard
MapLinker custom butttons function (MapLinker is the version 2 release of
the GeoBasemap Images+ product) which passes the x/y location of a click
point (and attributes of any map objects at that point) to any external
application. This is commonly an applicaiton (such as a VB or Microsoft
Access module) that presents a database form to enter external attributes.
When the user clicks OK on the external form, the applcation calls back to
MapLinker to invoke a MapBasic routine to add symbols on the mapper. Neat,
but quit a bit of coding if you don't have MapLinker.
I guess the approach that is right for you depends on whether this is a
one-off operation for a GIS tecko or part of a sequence that you need to
run regularly, or need to make available to less technical operators. But
it is my guess that the standard Mapping Systems "update points" module
will do the trick without needing custom development.
