Sets or clears the user-control flag, which is explained in the reference for AfxOleGetUserCtrl.
void AFXAPI AfxOleSetUserCtrl( BOOL bUserCtrl );
Specifies whether the user-control flag is to be set or cleared.
The framework calls this function when the user creates or loads a document, but not when a document is loaded or created through an indirect action such as loading an embedded object from a container application.
Call this function if other actions in your application should put the user in control of the application.
