Members

Public Methods

Name	Description
IOleInPlaceObjectWindowlessImpl::ContextSensitiveHelp	Enables context-sensitive help. The ATL implementation returns E_NOTIMPL.
IOleInPlaceObjectWindowlessImpl::GetDropTarget	Supplies the IDropTarget interface for an in-place active, windowless object that supports drag and drop. The ATL implementation returns E_NOTIMPL.
IOleInPlaceObjectWindowlessImpl::GetWindow	Gets a window handle.
IOleInPlaceObjectWindowlessImpl::InPlaceDeactivate	Deactivates an active in-place control.
IOleInPlaceObjectWindowlessImpl::OnWindowMessage	Dispatches a message from the container to a windowless control that is in-place active.
IOleInPlaceObjectWindowlessImpl::ReactivateAndUndo	Reactivates a previously deactivated control. The ATL implementation returns E_NOTIMPL.
IOleInPlaceObjectWindowlessImpl::SetObjectRects	Indicates what part of the in-place control is visible.
IOleInPlaceObjectWindowlessImpl::UIDeactivate	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.
