unsigned m_bInPlaceSiteEx:1;
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.
The data member m_spInPlaceSite points to an IOleInPlaceSite, IOleInPlaceSiteEx, or IOleInPlaceSiteWindowless interface, depending on the value of the m_bWndLess and m_bInPlaceSiteEx flags. (The data member m_bNegotiatedWnd must be TRUE for the m_spInPlaceSite pointer to be valid.)
If m_bWndLess is FALSE and m_bInPlaceSiteEx is TRUE, m_spInPlaceSite is an IOleInPlaceSiteEx interface pointer. See m_spInPlaceSite for a table showing the relationship among these three data members.
