How do i trap error from mappoint ?

I am trying to find addresses and pushpin it . But, I need a way to check whether the address is valid in mappoint or not, before calling findaddresresults.

(valid address is working fine.) But i have some junk in my database. It gives a pb error ' Error accesing external function....'

I am calling mappoint with address parameter as a separate application. ( not OLE)

TIA

I'm not sure if this is what you are looking for but here is how I would find if the address can be matched in mappoint. I'm using Visual Basic 6 with the ActiveX Control on my form Named MPC. The ADDR, CITY, ST and ZIP would be your variables.

Dim objmap As MapPointCtl.Map
Set objmap = MPC.ActiveMap
Dim objloc As MapPointCtl.Location


Set objLoc = objmap.FindAddress(ADDR, CITY, ST, ZIP, geoCountryUnitedStates)
If objLoc Is Nothing Then
Msgbox "Can't find address"
End if

But i am calling Mappoint as external applicaton. SO i need a way to check the validity before i call that function. Bcz, error comes before i check for the returned value.

You might try calling a MapPoint COM Add-in instead.. not trivial, but would be one way to attack the problem.
