When using the find nearby method I am having problems retrieving the custom data that I have imported into a MapPoint template. When iterating through the nearby location on a route the location returns null when it hits an imported recorded. All other locations are found.

The Import data is included in the total count and the custom data is found using the interface but not programmatically. I am just interested in finding the custom location on a particular route. Is there a better solution or does anyone know what I am doing wrong? Any help is appreciated. Here is my code.

Code:

oResults = oMap.ActiveRoute.Directions.FindNearby(0.1);
			int i = oResults.Count;
			IEnumerator ienum = oResults.GetEnumerator();
			ienum.Reset();
			//Loop through the enumerator
			while(ienum.MoveNext())
			{
				MapPoint.Location loc = ienum.Current as MapPoint.Location;
				if(loc != null)
				{
					//process the location
					ssCat = loc.Location.PlaceCategory.Name.ToString();
					ssName = loc.Name.ToString();
				}

I know it's been a while, but did you find a solution to this? I am experiencing the same problem with custom imported data. My code is nearly identical to yours - I am getting a "Count" of results, but I can't seem to iterate the results by casting them as Location objects. Any help would be appreciated. keith.mcgill@gmail.com

Hi,

Code:

MapPoint.Location loc = ienum.Current as MapPoint.Location;
            if(loc != null)

Do you mean this evaluate always to null ? Because in that case there is no Location object in the result set.
