Public Function TrackVector ( _ color As Color _ ) As Polyline |
Parameters
- color
- Type: System.Drawing..::.Color
The color of the partially completed line shown during the tracking operation.
Return Value
A new Polyline defined by two mouse clicks on the display.Remarks
This method returns a user-clicked vector on the map, using the specified line color while tracking. A vector is a special case of a Polyline with exactly two points, used only in ArcGIS Explorer during tracking operations (there is no vector geometry type).
This method will block the user interface (UI) thread until the user has completed tracking the vector. 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 BeginTrackVector(TrackDelegate), or the synchronous TrackVector()()() overload.
