Remarks
Note
To use this data member within your control class, you must declare it as a data member in your control class. Your control class will not inherit this data member from the base class because it is declared within a union in the base class.
This flag is checked by IOleObjectImpl::SetExtent and, if TRUE, SetExtent notifies the container of view changes. if this flag is set, the OLEMISC_RECOMPOSEONRESIZE bit in the OLEMISC enumeration should also be set.
