This class implements IUnknown and provides methods that enable a windowless control to receive window messages and to participate in drag-and-drop operations.
This class and its members cannot be used in applications that execute in the Windows Runtime.
Your class, derived from IOleInPlaceObjectWindowlessImpl.
Enables context-sensitive help. The ATL implementation returns E_NOTIMPL.
Supplies the IDropTarget interface for an in-place active, windowless object that supports drag and drop. The ATL implementation returns E_NOTIMPL.
Gets a window handle.
Deactivates an active in-place control.
Dispatches a message from the container to a windowless control that is in-place active.
Reactivates a previously deactivated control. The ATL implementation returns E_NOTIMPL.
Indicates what part of the in-place control is visible.
Deactivates and removes the user interface that supports in-place activation.
The IOleInPlaceObject interface manages the reactivation and deactivation of in-place controls and determines how much of the control should be visible. The IOleInPlaceObjectWindowless interface enables a windowless control to receive window messages and to participate in drag-and-drop operations. Class IOleInPlaceObjectWindowlessImpl provides a default implementation of IOleInPlaceObject and IOleInPlaceObjectWindowless and implements IUnknown by sending information to the dump device in debug builds.
