    code problem

    Hello people,

    I'm trying to execute the following code but get an exception on the map object (objmap.location) in the querycircle function. Any ideas...thanks

    PublicSub getshape()
    Dim objMap As MapPoint.Map
    Dim objDataSet As MapPoint.DataSet
    Dim objRecords As MapPoint.Recordset
    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)"
    location = objMap.FindResults("reston, va")
    objRecords = objDataSet.QueryCircle(objMap.Location, 1000)
    DoWhileNot objRecords.EOF
    lngcount = lngcount + 1
    MsgBox("Number of records in circle: " & lngcount)

    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.
