;IDataAdviseHolder
:The methods of '''IDataObject''' that pertain to data change notifications can be implemented by calling the methods of this interface.
:''Usually the stock implementation is used.''
;IOleAdviseHolder
:The methods of '''IOleObject''' that pertain to notifications can be implemented by calling the methods of this interface.
:''Usually the stock implementation is used.''
;IDropSource
:Implemented by objects that can be dragged, i.e. that can be the source of a drag-and-drop operations. When implemented it allows the object to draw drag-and-drop effects, and to specify when the object is dropped, or the drag-and-drop operation is cancelled.
;IDropTarget
:Implemented by objects that accept dropped objects, i.e. that can be the target of drag-and-drop operations. When implemented it allows the target to specify if a dropped object will be accepted, and what happens to an object after it is dropped.
;IOleCommandTarget
:Can be implemented by objects (OLE objects, OLE containers, and other objects) that wish to support certain standard commands. It allows callers to query if commands are supported, and to execute commands. Commands that an object might typically wish to implement may include things like "delete", "cut", "copy", "paste", "undo", "find", "print", "save", "zoom", and so on. Currently 58 standard commands have been defined, and they include commands commonly used by office software, web browsers and similar applications.
;IOleUndoUnit
:Represents an action that can be undone. It contains all information necessary to undo an action. It is created by objects and containers, so that undoable actions can be added to the container's '''IOleUndoManager'''.
:;IOleParentUndoUnit
::Allows an undo unit to contain other undo units. In essence this allows the undo unit to act as an undo stack, grouping undo units together. For example, if a macro is run, all undo-able actions performed by the macro may be grouped together in one undo unit.
;IOleWindow
:This interface represents a window of a container or contained object. It allows callers to obtain the handle of the window, and to toggle the context-sensitive help function. When the context-sensitive help function is turned on, typically the mouse-pointer changes to an arrow with a question mark to indicate that clicking a user interface element will result in opening a help window.
