Description |
|---|---|
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. |
Remarks
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.
