I have a comma separated list of multiple routes. Each line in the list is a point. Each route has a starting location and ending location, and some routes have one or more waypoints, with a sequence specified in the list. The points are already pre-ordered, like so:
route A,start,123 my rd,anytown,CA
route a,end,456 my rd,anytown,CA
route b,start,789 yr rd,anytown,CA
etc.
I am writing a VB app to take this data, map it, and draw straight lines connecting all points in each route. The result would be multiple unique, nonconnecting lines, one for each route.
Is there a way in Mappoint 2002 to either
1. create/display multiple routes or a collection or routes on a single map?
2. When importing the list, have it imported in the order it is provided? Using .importdata to create the dataset, and .queryallrecords to create the recordset, when I walk the recordset using .movefirst and .movenext, the recordset is not in the order that the comma delimited list is in.
Thanks for any help anyone can provide!

1. No. Only one route per map is allowed in MapPoint 2002.
2. This is interesting. The importdata method may have imported them in the desired order but how would you know? How can you impose order on the recordset created by the queryallrecords method? I don't think you can.

Hi,
We are a French company, we are currently writing a VB application which seems to be similar as yours... First of all we were trying to import multiple points (from 40 to 60 different points) in MapPoint, each point became a pushpin icon, and we wanted to "draw" multiple routes linking from 4 to 8 different pushpin icon to finally be able to see on the map multiple unique and non-connecting routes following the exact drawing of the roads on the map,... This seems to be impossible to do in MapPoint !
But we find an other way to do quite the same thing; in fact instead of following the exact drawing of the road , we are “drawing” lines between each pushpin icon using the “Addline” method (see Mappoint example below)... this enables us to have multiple routes on the map, having the exact distance of each route in our VB application...
I hope this will help you… let us know (eric.bogaert@tasq.fr)
Addline Method
Dim objApp As New MapPoint.Application
Dim objMap As MapPoint.Map
Dim objLoc1 As MapPoint.Location
Dim objLoc2 As MapPoint.Location
'application
Set objMap = objApp.ActiveMap
objApp.Visible = True
objApp.UserControl = True
‘having two different positions
Set objLoc1 = objMap.FindResults("Seattle, WA").Item(1)
Set objLoc2 = objMap.FindResults("Redmond, WA").Item(1)
Set objMap.Location = objLoc1
'adding a straight line between those two positions
objMap.Shapes.AddLine objLoc1, objLoc2
