    mappoint from PB

    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
    Roopa

    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.
