Mappers,
I'm having a problem with MapBasic. Is it possible to create a drop-down
list within a dialog box of files currently open. From what I gather,
drop-down boxes (popupmenu) seem to be pretty static, and I can't seem to
find a way of making it list files 'on the fly'. If anyone could help
People,
I'm sure there's an easy answer to this one. How can I draw a line a
specified length/distance, say 1.75km?
TIA,

After a plethora of responses, I now feel like the only person on the list
who didn't know this one. For those of you who also don't know, the answer
is:
- draw a line
- double-click on it
- enter the correct length in the dialog box
Another method, and far more accurate, is to use the Cogo
MI-L'ers,
A colleague of mine was trying to draw a line (using the line tool) from one
point to another. The problem was, MI drew the line from the centre
outwards, much like the radius/marquee select tool. It was almost as if it
wanted to draw a circle but only with a line. All very strange.
MI-Listers,
Okay people, how much do you know about Date functions in MI? Is it possible
to select a row from Table1 where the date is within 10 days (for example)
from another row in Table2? As far as I can tell, I can only select rows
based on month, day of the week, day or year.
Thanks in

Dearest MapInfo users,
I have a problem that's been plaguing me for a few days now. I have a table
with two columns, one containing an ID and the other a date. Most of the IDs
appear more than once, with different dates each time. What I need to find
out is the earliest and latest date for each

The solution that I finally used was from Peter who suggested the following

Thanks to all those who helped me with my node snapping dilema (Steve W,

correct projection and everything is now working fine.

Just a quick question regarding snapping to nodes.
What is the extreme limit of MI's snapping abilities? I'm trying to snap one
boundary to another one, with 'SNAP' turned on (the snap tolerance doesn't
make a difference here!) but when zoomed in you can clearly see that the two

I'm trying to edit a table, but when I do I get an error message saying that
someone else is editing the table so I can't do anything. Trouble is, no one

I would like to have a couple of map windows open, each showing different

Dear all,
Has anyone out there successfully linked an Excel table to MI (and
vice-versa)? Unfortunately we can't use Access because we use many
formulas to calculate the data, and since the data is constantly
changing we can't just open up the Excel table in MI. Anyone got any
ideas?

Dear list,
Is it possible for MI to create contour lines? I need to produce a
map showing different rainfall ranges across an area, and thought
this would be the best way.
All help appreciated.
