Hello.

OnlineMapsUtils.NearestPointStrict method is created for internal use in drawing API, so it is not documented.
But in this particular situation this method is very useful.

How it works:
You know that the user should be somewhere between points A and B.
You pass to the method the user's coordinates (U) and the coordinates of points A and B.
The method returns the coordinates of the point (C) on the segment AB, which is closest to U.
You calculate the distance between points C and U.
If the distance is more than 150 feet, you need to find a new route.
Example attached.

Yes, you can assign TextValue.value to an integer variable.

Hey Alex,
I am trying to find the users distance from the route, so if the user gets a certain distance from the route (makes a wrong turn), i can trigger a re-calculation of the route from the users current GPS location. In this post (http://forum.infinity-code.com/viewtopic.php?id=743) you mentioned using OnlineMapsUtils.NearestPointStrict, however i could not find it in the API docs. could you explain how to use it? or if there is a better way?

I am already using distancebetweenpoints to display the next step instruction when the user is within 150 feet of the next point.

Also, OnlineMapsGoogleDirectionsResult.Step.distance returns a TextValue, Does this mean I can just assign the returned value to an integer variable or is some conversion needed? I looked at the distance and duration example that uses this but i wasn't sure.

Thanks for your help!
