| Programming in VB.Net I'm trying to give a location in Lat/Lon, and return a list of attributes at that location. I can get a map, and place pushpins ok, but the next part is causing an error. The code I have so far (to find 1 location) is: Code: 'Get a location on the map
oloc = omap.FindResults("51.577141, 0.291178").Item(1)
'Find nearby places 0.5 miles from that location
MsgBox("Closest place: " + oloc.FindNearby(0.5).Item(1).Name)
The above code came straight off MSDN. Can anyone help with this problem, or expand the code to produce a full list of attributes at that location? Thanks Nick         |

You need to use the "GetLocation method" insted of "FindResults Method"

The reason you got the error (The requested member of the collection does not exist. Use a valid name or index number) is because there was not anything nearby. Try this example. Put this code in a command button and see if it works better. It should find Pushpin1. Code: Try
Dim omap As MapPoint.Map
omap = AxMappointControl1.ActiveMap
Dim oloc As MapPoint.Location
Dim opin As MapPoint.Pushpin
oloc = omap.GetLocation(51.577141, 0.291178, 250)
opin = omap.AddPushpin(oloc, "Pushpin1")
opin.BalloonState = MapPoint.GeoBalloonState.geoDisplayBalloon
opin.Location.GoTo()
'Find nearby places 0.5 miles from that location
MsgBox("Closest place: " + oloc.FindNearby(0.5).Item(1).Name)
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
