In PHP I can use this code:
$url = "http://maps.googleapis.com/maps/api/distancematrix/json?origins=$location1& destinations=$location2&mode=bicycling&language=en-EN&sensor=false";
$data = @file_get_contents($url);
$obj = json_decode($data);
$arr = (array)$obj;
to get an array of values that return the distance between 2 locations.
Is this kind of web interaction possible with VSTO? I have Googled high and low and nothing I search is giving me any results to work with.
Ergo, I think I am missing something.
