IOleObjectImpl::SetExtent
Sets the extent of the control's display area.
STDMETHOD(SetExtent)(
DWORD dwDrawAspect,
SIZEL* psizel
);
Remarks
Otherwise, SetExtent stores the value pointed to by psizel in the control class data member CComControlBase::m_sizeExtent. This value is in HIMETRIC units (0.01 millimeter per unit).
If the control class data member CComControlBase::m_bResizeNatural is TRUE, SetExtent also stores the value pointed to by psizel in the control class data member CComControlBase::m_sizeNatural.
If the control class data member CComControlBase::m_bRecomposeOnResize is TRUE, SetExtent calls SendOnDataChange and SendOnViewChange to notify all advisory sinks registered with the advise holder that the control size has changed.
See IOleObject::SetExtent in the Windows SDK.
