Suzanne,
Here are a few answers for you. Hope they help.
First of all, to cycle through your points, you'll want to do something like
the following:
Spin through all the points in the layer. (Create a new Feature object, and
do a For Each ftr In lyrNewLayer.AllFeatures.)
Create a new Point object for each point in the layer. Use the Point.Set
with the ftr.CenterX and ftr.CenterY properties.
Stuff each Point object into a new Points collection, one at a time.
Use the MapX.FeatureFactory object to create a new line based on the Points
collection.
Sorry for the pseudo-pseudocode. I'd supply the actual VB code, but it
would probably take about half an hour to type it up, plus another 15
minutes to explain in detail.
Secondly, yup. You can join several tables together in the SQL statement
for you ODBCQueryInfo object.
Third, right again. The documentation is (I'm being polite here) "sketchy".
There is a free User's Guide downloadable from the MapX beta web site. Go
to www.mapx.com, follow the links to the new beta, and you'll see a PDF
developer's guide you can download. It's still a work in progress, and it
does contain some MapX 4 stuff, but it ought to help.
Good luck,

Subject: MI Referencing points on layer
Hi,
I am new to MapX and I have a couple of relatively simple questions. I
am creating a layer of points through X/Y data binding using the ODBC
QueryInfo object.
Once I get my layer on the map, I am having trouble getting the specific
points that I want. (The end goal is to connect certain points with
lines).
How can I reference this points once they are on the layer and in the
dataset? Also, is it possible to bring columns from multiple tables in
through the SQL connect string?
Also, I discovered that there wasn't much documentation included in the
MapX software and the help files don't have everything I need. Could
anyone point me to a good source of MapX info?
Thanks,
-Suzanne
