I am trying to verify a number of addresses, all of which lack the city
information. Is there any way to filter the results returned from a find
address, so that the only address objects returned are those that are in one of the four cities I am interested in? (All of the addresses are in the same state.)

I tried working with the ThresholdScore to resolve this issue, but it didn't
give me exactly what I want.

Can I use a FilterExpression to do this, if so, how? What about trying to match EntityType? (And how would I do this?)

Thanks!

Hi, if you have Postal or Zip codes, this method I wrote once might help you. Sorry about the indenting...it looks much better in Vis Studio.

Private Sub DeObfuscate(ByVal fr As MapPoint.FindResults, ByVal Results As GeoCodeResults, ByVal Map As Map, Optional ByVal MaxDistanceFromPcode As Double = 1)

'this function attempt to disobfuscate a "no good results" by testing all
'returned locations and comparing them to the location of a postal code. If
'an address level location is close to the postal code, it is deemed to be the valid one.

Dim aLoc As MapPoint.Location
Dim i As Long

'look for a postal code match
For i = fr.Count To 1 Step -1

aLoc = CType(fr.Item(i), Location)

If aLoc.Type = GeoShowDataBy.geoShowByPostal1 Then
Results.PcodeLoc = aLoc
Exit For
End If

Next

'if a postal code location was found, then scan the list again
'to see if there is a trust-worthy location
If Not Results.PcodeLoc Is Nothing Then
i = 0
For Each aLoc In fr
'scan each plausible location but give up after maximim of 5
'to avoid wasting time.
i = i + 1
If i > 5 Then
Exit For
End If

If aLoc.Type = GeoShowDataBy.geoShowByStreetAddress Or aLoc.Type = GeoShowDataBy.geoShowByDefault Then

If Map.Distance(aLoc, Results.PcodeLoc) < MaxDistanceFromPcode Then
Results.Loc = aLoc
Exit For
End If

End If
Next
End If

End Sub
