unsigned m_bWndless:1;
Remarks
Flag indicating the control is windowless.
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 TRUE, m_spInPlaceSite is an IOleInPlaceSiteWindowless interface pointer. See m_spInPlaceSite for a table showing the complete relationship between these data members.
