This project was brought about by a customer request. They wanted a method of clicking on a Google Map and having the Longitude and Latitude come up that could then be cut and pasted into a FileMaker record. The project was for wildlife observation software sold as a FileMaker Runtime. Google has recently changed their Maps API (again) and it broke an existing method in the Runtime.
Very cool! Be sure to read the whole thing, as he encountered some difficulties that he found ways around.
