~CNiCursors()

Destructor.

	CNiCursor	Add()	Adds a cursor to the collection and returns the new cursor.
	static const IID &	GetIid()	Returns the globally unique identifier (GUID) of the ActiveX interface to which this class connects.
	CNiCursor	Item( long cursorIndex )	Returns the specified cursor from the collection.
	CNiCursor	Item( const CString& cursorName )	Returns the specified cursor from the collection.
	const CNiCursors &	operator =( const CNiCursors& source )	Assignment operator.
	void	Remove( long cursorIndex )	Removes the specified cursor from the collection.
	void	Remove( const CString& cursorName )	Removes the specified cursor from the collection.
	void	RemoveAll()	Removes all cursors from the collection.

1. Set the snap mode and visibility of the first cursor on the graph.

    CNiGraph graph;
    CNiCursor cursor = graph.Cursors.Item(1);
    cursor.SnapMode  = CNiCursor::SnapNearestPoint;
    cursor.Visible   = true;

2. Set the crosshair style.

    CNiGraph graph;
    graph.Cursors.Item(1).CrosshairStyle = CNiCursor::CrosshairMinorXMinorY;

3. Add an additional cursor to the graph and hide it.

    CNiGraph graph;
    CNiCursor cursor = graph.Cursors.Add();
    cursor.Visible = false;

4. Remove all cursors from the graph.

    CNiGraph graph;
    graph.Cursors.RemoveAll();

5. Change the name of the first cursor.

    CNiGraph graph;
    graph.Cursors.Item(1).Name = "Time";

Subsequent accesses to this cursor must now use "Time" for its name. For example,

    graph.Cursors.Item("Time").Visible = true;
