Return Value
A new Polyline defined by a series of mouse clicks on the display.Remarks
This method returns a user-clicked Polyline on the map, using the specified line color and width while tracking.
This method will block the user interface (UI) thread until the user has completed tracking the Polyline. The method can be cancelled if the ESC key is pressed after the method has been called or the CancelTracking()()() method is called; in this case the method will return nullNothingnullptra null reference (Nothing in Visual Basic).
Alternatively you may wish to try the asynchronous alternative BeginTrackPolyline(TrackDelegate), or the synchronous TrackPolyline()()() overload.
