Hi!
I have two different applications one test-application that displays a map and another one that is just a server application.
Both have worked fine for a long time but recently I got a complaint for a calculated distance.

When I run my server application I get approx: 9.75 km.
Using the test-application I get approx: 15.7 km which seems much better.

The positions are:
Start Lat: 59.2686233333333
Long: 18.019825

Stop Lat: 59.3085966666667
Long: 18.2301466666667

Im using MapPoint 2006 (Europe)
The code for the server application looks like:

Map map = MapPointApp.ActiveMap;
map.ActiveRoute.Clear(); //clear the route if one exists
Route route = map.ActiveRoute;
route.Waypoints.Add(fromLocation, "Start");
route.Waypoints.Add(toLocation, "End");
route.Calculate();
return route.Distance;


And the code for the test-application looks like:

axMappointControl1.ActiveMap.ActiveRoute.Clear(); //clear the route if one exists
Route oRoute = axMappointControl1.ActiveMap.ActiveRoute;
oRoute.Waypoints.Add(FromLocation, "Start");
oRoute.Waypoints.Add(ToLocation, "End");
oRoute.Calculate();
axMappointControl1.ItineraryVisible = false; //hide the directions pane
MessageBox.Show(oRoute.Distance + " km");

Any help would be appreciated / Michael

Michael,

I plotted the route and got all highway 16.x km
Are the "Preferred" settings different on the machines?

Hi Mike!
I'm not sure whatt settings you're referring to, but when I tried to figure out what was happening I ran both applications on the same machine.

When you say "plotted the route" I assume that you used the ActiveX control. So it seems that using that you get almost the same result as I do.

It's the other result when I'm using the "Microsoft MapPoint 13.0 Object Library (Europe)" that I get the strange distance.

Hi,

Possible the default preferred settings are different using the object model versus the activeX control. You have to set them in both of the programs the same.

Hi!
Now I understand that I misunderstood the first reply

How do I check/set default preferred settings?

Thanks in advance / Michael

Can this problem in any way have anything to do with the fact that I upgraded fråm version 2004 to 2006?

Regards / Michael

Is MapPoint 2004 still installed? Maybe when you run the ActiveX it is still opening MapPoint 2004.

Hi!
No I deinstalled 2004 before installing 2006 and after reading your post I also searched my harddrive to make sure there was no old version of MappointControl.ocx laying around.

Check in the Help file, there is the PreferredRoads property of the DriverProfile object. Also, there are methods to reset the roads and PreferredSpeeds:

DriverProfile object

The DriverProfile object contains preferences for generating routes, such as travel time, methods for determining route costs, preferred roads, and so on. This object is invalidated after the map is closed.

Methods

ResetPreferredRoads
ResetSpeeds

Thanks a lot!
I'll try it out and see what I can find.
