| How to find nearest city? I work with MS MapPoint 2002 under Delphi using TOleContainer. Everything works fine, but I have this problem: I have Lat and Long and want to search for nearest city. I need name of the city and name of the country, where it resides. I use this code: Code: Dist:= 1; Loc:= self.GetLocation(X, Y); Results:= Loc.FindNearby(Dist); while (Results.Count = 0) and (Dist < CMaxDist) do begin Results:= Loc.FindNearby(Dist); Dist:= Dist*2; end; if Results.Count > 0 then //here I have all locations ... Thanks for all replies. Bye Petr         |

One of the problems with the FindNearby method is results are limited to the CURRENTLY VISIBLE PlaceCategory objects (Like Restaurants, Airports etc..) So even if there is/was a way to get the city from the nearest "Place" the results could not be depended on. A better approach might be what David is exploring (Also Delphi). http://www.mp2kmag.com/mappoint/disc...pic.asp?t=3187

Hi Petr, as said above I am doing the same sort of thing although I am searching for the nearest road from a point so I can get a postcode. The Map.ObjectsFromPoint method: Code: mpResults := mpMap.ObjectsFromPoint(mpMap.LocationToX(mpLocation), mpMap.LocationToY(mpLocation));
