Methods

	Name	Description
	ActivateDocumentIfOpen(String)	Activates a document with the specified moniker, if the document is open.
	ActivateDocumentIfOpen(String, Guid)	Activates a document with the specified moniker and logical view, if the document is open.
	CreateObjectNode	Creates a new node in the data view hierarchy, but one without context and that is not placed anywhere in the hierarchy tree.
	DropObjectNode	Drops an existing node that represents an object from the data source from the data view hierarchy.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	ExecuteCommand(Int32, OleCommand)	Executes an OLE command without arguments directly on the data view hierarchy.
	ExecuteCommand(Int32, OleCommand, Object)	Executes an OLE command on the data view hierarchy with arguments.
	ExecuteCommand(Int32, OleCommand, OleCommandExecutionOption, Object)	Executes an OLE command directly on the data view hierarchy, with a specific execution option and arguments.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetChildSelectionTypes	Retrieves an array of the object types enumerated when a parent node is expanded to show its child nodes.
	GetChildStaticNodeIds	Retrieves an array of the static node IDs that are children of the specified item ID.
	GetCommandStatus(Int32, OleCommand)	Retrieves the status of an OLE command.
	GetCommandStatus(Int32, OleCommand, OleCommandTextType)	Retrieves the status of an OLE command with a request for a particular type of command text.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetItemIdFromNodePath	Infers the item ID of a node in the data view hierarchy given a path to the node.
	GetNodeId	Retrieves the node ID as specified in the data view support XML from an item ID.
	GetNodeName	Retrieves the display name of a specified node.
	GetNodePath	Infers a node path from the location of a node in the data view hierarchy.
	GetObjectIdentifier	Retrieves the data-source-specific identifier of the object associated with the node matching the specified item ID.
	GetObjectProperty	Retrieves a property of a data object associated with the node matching the specified item ID.
	GetObjectType	Retrieves the type of the data object associated with the node matching the specified item ID.
	GetProperty	Retrieves a hierarchy property.
	GetSelectedItems	Retrieves an integer array representing item IDs for currently selected nodes in the tree.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDocumentOpen(String)	Retrieves a Boolean value that indicates whether a document with a particular moniker is currently open.
	IsDocumentOpen(String, Guid)	Retrieves a Boolean value that indicates whether a document with a particular moniker and logical view is currently open.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetNodePath	Sets the node path for a node identified by a particular item ID.
	SetProperty	Sets a specified hierarchy property.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

Use this class to make communicating with the data view hierarchy object from managed code simpler. Using this class is preferred over talking directly to the IVsHierarchy or IVsUIHierarchy interfaces.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
