    Dim objMap As MapPoint.Map
    Dim objDataSet As MapPoint.DataSet

    Dim location As MapPoint.FindResults
    Dim objfield As MapPoint.Field
    Dim lngcount AsInteger
    AxMappointControl1.NewMap(MapPoint.GeoMapRegion.ge oMapNorthAmerica)
    objMap = AxMappointControl1.ActiveMap
    objDataSet = AxMappointControl1.ActiveMap.DataSets.GetDemograph ics(MapPoint.GeoCountry.geoCountryUnitedStates)
    Dim datafieldkey AsObject = "Population (2002)"
    Stop
    location = objMap.FindResults("reston, va")
    objRecords = objDataSet.QueryCircle(objMap.Location, 1000)

    Re: code problem

    Do you mean "objMap.Location"?

    Or do you mean use your "location" variable? Note that the find methods return a FindResults object. This reports the results quality an a collection of results.
    You might need something like "location.item(1)" instead, to choose the first result.
