 *  we indicate whether the object can currently be activated
 *  in-place.  Linked objects, for example, cannot, meaning we
 *  return S_FALSE.
 *
 * Parameters:
 *  None
 *

 *                  object in this site, S_FALSE if not.

 *  changes at this point.  See OnUIActivate.

 *
 * Parameters:
 *  fUndoable       BOOL indicating if the object will actually

 *  The container should call IOleInPlaceObject::UIDeactivate.

 *  Provides an in-place object with pointers to the frame and

 *  IOleInPlaceUIWindow) such that the object can do border
 *  negotiation and so forth.  Also requests the position and
 *  clipping rectangles of the object in the container and a
 *  pointer to an OLEINPLACEFRAME info structure which contains
 *  accelerator information.
 *
 *  Note that the two interfaces this call returns are not
 *  available through QueryInterface on IOleInPlaceSite since they
 *  live with the frame and document, but not the site.
 *
 * Parameters:
 *  ppIIPFrame      LPOLEINPLACEFRAME * in which to return
 *                  the AddRef'd pointer to the IOleInPlaceFrame.
 *  ppIIPUIWindow   LPOLEINPLACEUIWINDOW * in which to return
 *                  the AddRef'd pointer to the document's
 *                  IOleInPlaceUIWindow.
 *  prcPos          LPRECT in which to store the object's position.
 *  prcClip         LPRECT in which to store the object's
 *                  visible region.
 *  pFI             LPOLEINPLACEFRAMEINFO for accelerator info.

 *                  extents by which the container should scroll.

 *  prcPos          LPCRECT containing the new size of the object.
