We're trying to import a file from a C# dll into MapPoint, and can get it to read the data just fine, but we are having trouble with MapPoint not recognizing all of the addresses. Currently, our file contains not only address information, but latitude and longitude as well (under the headers of Lat and Lon). Is there any options we can set, or any methods we can use that will allow us to tell MapPoint to use the latitude and Longitude in place of, or in addition to the address? So far I've not found any, but I could be looking in the wrong place anyway. Thanks.
