The EXTCONN enumeration specifies the type of external connection existing on an embedded object. Currently, the only supported type is EXTCONN_STRONG, meaning that the external connection is a link. This EXTCONN constant is used in the IExternalConnection::AddConnection and IExternalConnection::ReleaseConnection methods.
typedef enum tagEXTCONN { EXTCONN_STRONG = 0X0001, EXTCONN_WEAK = 0X0002, EXTCONN_CALLABLE = 0X0004 } EXTCONN;
