Hello,
I use the FindNearby fuction in a C# program to determine the nearest street to a position given by latitude/longitude. I have the following problem: the returned FindResult can contain Location and Pushpin objects. How can I find out the type of each element in the FindResult? It seems to me they are all of the type ComObject. I'm just trying to find out the nearest street.

Bye,

Hi,

Code:

            FindResults Nearby = PP.Location.FindNearby(10);
            foreach (object o in Nearby) {
                if (o is Pushpin)
                    // this is a pushpin
                else if (o is Location)
                    // this is a Location

If you only need Location and dont need any other you can do following:

Code:

            FindResults Nearby = PP.Location.FindNearby(10);
            foreach (object o in Nearby) {
                Location loc =  o as Location
                if (o != null) {
                    // voila !

FindNearest only give you "points of interest", so no streets. But of course these points of interest have a streetaddress in many case.

In many cases?

Hmmm, I'm having problems here with FindNearby. I was using it fine, but when you ask for the nearest ATMs within 20 miles say, it isn't much use if a dozen of them are all called "Bank of America". I need some (human) way to distinguish them, eg. street address. At the moment I'm finding StreetAddress is nothing.

Let me see how many are affected, it was looking like all of them a few minutes ago, though...

Looks like you're right Wilfried. Virtually all the POIs I've tried in the Dallas area have street information. A handful don't - just enough to crash my program unless I check the StreetAddress property for null/nothing!

Hi Richard,

Yes indeed the null checking filters them out. Is there something you like me to test/help on this ?

No I'm fine Wilfried. I was adding my own code to my own program and found it crashing. It is one more thing to check, but at least the data is there in most cases - which I think is enough for this customer.
