Hi Listers
 
- I have a table of Elementary Street Units (ESUs), essentially
polylines, each with an ESU-ID, all comprising my STREETS table
- This I inherited
- I select ESUs from this table and save them to another table, RouteESU
(created by me), along with a Route ID composite key, to store a bus
route, copying the STREET obj to this so routes appear on the map.
- I need to write a copy of my tables to Visual Foxpro-like tables
(.dbf) when I've updated the Routes table above.  Similarly, when a
route is deleted in my VFP application, I need to delete the Route-ESU
records pertaining to it
 
Now somewhere along the line the Route-ESU table has lost its objects
and, although I can browse the table and the records are there, I can't
map them.
 
I have 3 problems here:
 
1.  How did the table lose its objects?
2.  I want to reinstate the objects but I can't figure out HOW I did it
in the first place.  There is, and was, no X/Y, Eastings/northings etc.
in it.  When you go to the "Create Points" menu item it wants to know
what columns to get the X and Y co-ords from;  there's only the Route ID
and ESU ID.
3.  I looked to the "parent" STREETS table to see how that was geocoded
and I can't see what THAT is based upon, there being no obvious x/y,
E/N.  Besides, I've never geocoded polylines so don't know how they get
their x1/y1, x2/y2 and Centre x/y.
 
Can someone help me with this please?  Although I'm getting quite
skilled now at programming in MB, it's the initial setting up/MI side of
things that I'm green at.
 
'ppreciate it
