The UndoManager type exposes the following members.

Constructors

	UndoManager(IServiceProvider, IOleUndoManager)	Create a new UndoManager with the specified service provider and IOleUndoManager.

Properties

	Name	Description
	IsDirty
	VSUndoManager	This is what should be pushed to the SEID for a window frame that wants to use this undo manager. We can't wrap IOleUndoManager in a managed object because the property browser QI's for MS.VS.NativeMethods.IOleCommandTarget, which is private, so we can't implement it on this class.

Methods

	Name	Description
	Add	Adds an undo unit to the stack and updates the UI.
	DiscardUndoStacks	Throws away undo/redo stacks. If the bool is true, then in addition to discarding the undostack the routine will mark the stack as clean.
	Dispose()	Releases all resources used by the current instance of the UndoManager class.
	Dispose(Boolean)	Disposes the state of this object.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Exec	Implementation of IOleCommandTarget interface. Passes the call to the wrapped IOleUndoManager.
	Finalize	Finalizer. (Overrides Object.Finalize().)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnInterveningUnitBlockingLinkedUndo	Indicates that the undo manager is blocking another undo manager from executing a linked action.
	QueryStatus	Implementation of IOleCommandTarget interface. Passes call to the wrapped IOleUndoManager instance.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
