A synchronous (blocking) call returning a new vector (Polyline with two points) at the location of two mouse clicks on the display, using the specified line color while tracking.

Namespace:  ESRI.ArcGISExplorer.Mapping

Assembly:  ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.1500 (2.0.0.1500)

Syntax

C#
public Polyline TrackVector(
	Color color
)
Visual Basic (Declaration)
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 use an asynchronous equivalent, see the BeginTrackVector methods.
