IOleWindow

The IOleWindow interface methods allow an application to obtain the handle to the various windows that participate in in-place activation, and also to enter and exit context-sensitive help mode.

Five other in-place activation interfaces are derived from the IOleWindow interface. Containers and objects must implement and use these six interfaces in order to support in-place activation. The following table briefly summarizes each of these interfaces:

IOleWindow
The base interface. Implemented and used by containers and objects to window handles and manage context-sensitive help.
IOleInPlaceObject
Implemented by objects and used by an object's immediate container to activate and deactivate the object.
IOleInPlaceActiveObject
Implemented by objects and used by the top-level container to manipulate the object while it is active. Provides a direct channel of communication between an active object and its frame and document windows.
IOleInPlaceUIWindow
Implemented by containers and used by objects to manipulate the container's document window.
IOleInPlaceFrame
Implemented by containers and used by objects to control the container's frame window.
IOleInPlaceSite
Implemented by containers and used by objects to interact with the in-place client site.

These interfaces can be arranged in three hierarchical levels with various interfaces implemented at each level. Calls that install user-interface menus and frame adornments, activate and switch between windows, and dispatch menu and keystrokes take place between the top-level container and the active object. Calls that support activating, deactivating, scrolling, or clipping span the containment hierarchy, with each level performing the correct actions.

When to Implement

The inherited methods of this interface are implemented by all in-place objects and containers.

When to Use

Use this interface to obtain the window handle to the windows associated with in-place activation (frame, document, parent, and in-place object). It is also used to enter and exit context-sensitive help.
