/*
 * CImpIOleInPlaceObject::GetWindow
 *
 * Purpose:
 *  Retrieves the handle of the window associated with the object
 *  on which this interface is implemented.
 *
 * Parameters:
 *  phWnd           HWND * in which to store the window handle.
 *
 * Return Value:
 *  HRESULT         NOERROR if successful, E_FAIL if there is no
 *                  window.

 * CImpIOleInPlaceObject::ContextSensitiveHelp
 *
 * Purpose:
 *  Instructs the object on which this interface is implemented to
 *  enter or leave a context-sensitive help mode.

 * Parameters:
 *  fEnterMode      BOOL TRUE to enter the mode, FALSE otherwise.
 *
 * Return Value:

 *
 * Purpose:
 *  Instructs the object to deactivate itself from an in-place state

 *
 * Parameters:
 *  None
 *
 * Return Value:
 *  HRESULT         NOERROR or an error code

 *
 * Purpose:

 *  but to do no other deactivation.  The object should just hide
 *  the UI components but not destroy them until InPlaceDeactivate
 *  is called.
 *
 * Parameters:
 *  None

 *
 * Purpose:
 *  Provides the object with rectangles describing the position of
 *  the object in the container window as well as its visible area.
 *
 * Parameters:
 *  prcPos          LPCRECT providing the object's full rectangle
 *                  relative to the continer's document.  The object
 *                  should scale to this rectangle.
 *  prcClip         LPCRECT describing the visible area of the object
 *                  which should not draw outside these areas.
 *
 * Return Value:
 *  HRESULT         NOERROR or an error code
