Hello Marjorie and Listers,

I think this boils down to a matter of taste. I, for one, have to
disagree with your about "Arial Narrow." Some fonts that do well on
screen are, as you mentioned, "Lucida", then there's "Verdana", and
then there's always "Microsoft Sans Serif."
>- How big will the streets file be when I convert it to the editable file

Very very big. We don't know exactly how big, but it will be about
12 to 17 times as large as the compact version. We'd recommend selecting
and exporting only the regions you'll absolutely need.

There's a lot in this question. The "file pointers" are nothing more
than the full "pathname" of the file. That is to say, that the way the
map "remembers" which geographic files you used is that it simply
stores the full pathname of the geographic files. So, if you used
your geocoded customer layer in Maptitude folder it would refer to
that layer with something like "c:\program files\Maptitude\customer.dbd"
and then if you used the streets layer from your CD ROM it would
use "D:\ccstreet.cdf." These pathnames get saved as part of the map
file; when you open the map, the software goes and looks for exactly
these path and file names to re-open and recreate the map. The situation
Marjorie poses, where the streets CD is no longer in the CD ROM drive,
(or perhaps the customer layer's been moved, etc.) comes up all the
time. This is perfectly OK. When you open the map, the software first
goes looking for the geographic files it needs in the specific paths
that are saved as part of the map. If they're not there, in the path
that the map file initially saved, the software automatically starts
searching elsewhere, namely in all the paths you specify in the
"Search Path" box of the Edit-Preferences dialog box. After checking in
every directory listed in the "Search Path" box, it will give you the
"file not found" dialog box which has a "Browse" button allowing you
to browse for the new location of the file yourself. Once the software
has found all the geographic files and opened the map, you can force
the map to remember all the new paths simply by saving the map.
Secondly, the installer doesn't install the streets geographic file.
It installs the so-called "street speed-up files" , a set of
various index files which greatly increases the performance of
address matching. However, the streets geographic file itself,
CCSTREET.CDF, does not get copied over, though this can be done
manually, quite simply by using windows explorer.
I don't think anyone's yet made an add-in for detailing the contents
of a map file into a text file. I'll attempt to contribute a
suggested solution sometime soon.

This is relatively simple. You've got the form already to accept
the user input. All you really need to do in Maptitude is have a
point layer with a field for each field in your form, then a script
tied to the "submit" button that adds a new record to the database
and fills in the user-submitted values. For a point layer this
can be accomplished with one GISDK function, "AddRecord()". In
VBScript this would look something like:
' Read inputs from the HTML form
user_name = Request("usr")
phone_number = Request("phn")
type = Request("typ")
...
...
...
' assume the user's mouse-click on the map was captured
' earlier
new_values = Array(Array("User Name", user_name), _
Array("Phone", phone_number), _
Array("Type", type), _
...
)
new_rh = Gisdk.Function("AddRecord", "Bike Routes", new_values)
> > 4. What's the largest field size?
It depends on what type of table you're using. All the specs are
in the Maptitude User's Guide (and On-Line Help), see page 388 and
389.
I hope this helps to answer some of your questions.
