Problem building one way routing index

Hello,

I Have a problem when I try to search the short path between to points.

System.OutOfMemoryException: Se produjo una excepción de tipo 'System.OutOfMemoryException'. en ThinkGeo.MapSuite.Routing.x7f88fd6dcd379046.ReadString(Int32 byteLengthOfSting) en ThinkGeo.MapSuite.Routing.x919970c45e3a742e.ReadRoad(Int32 roadPosition, String featureId) en ThinkGeo.MapSuite.Routing.x919970c45e3a742e.ReadRoadById(String id) en ThinkGeo.MapSuite.Routing.RtgRoutingSource.GetRouteSegmentByFeatureIdCore(String featureId) en ThinkGeo.MapSuite.Routing.RoutingSource.GetRouteSegmentByFeatureId(String featureId) en ThinkGeo.MapSuite.Routing.RoutingEngine.GetRouteCore(String startFeatureId, String endFeatureId) en ThinkGeo.MapSuite.Routing.RoutingEngine.GetRoute(String startFeatureId, String endFeatureId) en EjemplosMS.Form1.ShowTheShortestPath(RoutingLayer routingLayer) en C:\Documents and Settings\mario_aldana\Mis documentos\Visual Studio 2008\Projects\EjemplosMS\EjemplosMS\Form1.cs:línea 94

I think that the problem is when I build the index file. In the proyect attached I have the option to rebuild the route index.

Thanks

mario,

The error is caused by the code in BuildRouteIndex class at line 28, which is shown as below:

RtgRoutingSource.GenerateRoutingData(rootPath + "med_laureles_polyline", featureSource, BuildRoutingDataMode.Rebuild, "");

The input parameter "rtgFilePathName" misses the suffix ".rtg", please use the code blow:

RtgRoutingSource.GenerateRoutingData(rootPath + "med_laureles_polyline.rtg", featureSource, BuildRoutingDataMode.Rebuild, "");

Thanks for handing the error, and we will add some validations in the future.

Johnny,
