Remarks

• The DirectionAction enumeration is used with the Direction.Action property.

• The Waypoint.Name property allows you to define names for waypoints, which appear in the Depart and Arrive lines of the itinerary.

• If the Direction.DirectionType property value is Warning and the Direction.Action property value is KeepLeft, KeepRight, KeepStraight, TurnLeft, or TurnRight, the road name stays the same.

Example

'Calculate a route and add a note for construction
Dim latLongs(1) As LatLong
latLongs(0) = New LatLong()
latLongs(0).Latitude = 40
latLongs(0).Longitude = -120
latLongs(1) = New LatLong()
latLongs(1).Latitude = 41
