Public method ExecuteCommand(Int32, OleCommand, Object) Executes an OLE command on the data view hierarchy with arguments.
Public method ExecuteCommand(Int32, OleCommand, OleCommandExecutionOption, Object) Executes an OLE command directly on the data view hierarchy, with a specific execution option and arguments.
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetChildSelectionTypes Retrieves an array of the object types enumerated when a parent node is expanded to show its child nodes.
Public method GetChildStaticNodeIds Retrieves an array of the static node IDs that are children of the specified item ID.
Public method GetCommandStatus(Int32, OleCommand) Retrieves the status of an OLE command.
Public method GetCommandStatus(Int32, OleCommand, OleCommandTextType) Retrieves the status of an OLE command with a request for a particular type of command text.
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)

Public method GetObjectProperty Retrieves a property of a data object associated with the node matching the specified item ID.
Public method GetObjectType Retrieves the type of the data object associated with the node matching the specified item ID.

Public method IsDocumentOpen(String, Guid) Retrieves a Boolean value that indicates whether a document with a particular moniker and logical view is currently open.
Protected method MemberwiseClone Creates a shallow copy of 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.
