CComControlBase::m_bResizeNatural
Flag indicating the control wants to resize its natural extent (its unscaled physical size) when the container changes the control's display size.
unsigned m_bResizeNatural:1;
Remarks
This flag is checked by IOleObjectImpl::SetExtent and, if TRUE, the size passed into SetExtent is assigned to m_sizeNatural.
The size passed into SetExtent is always assigned to m_sizeExtent, regardless of the value of m_bResizeNatural.
Notes
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.
