EXTCONN

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;

If this value is specified, the external connection must keep the object alive until all strong external connections are cleared through IExternalConnection::ReleaseConnection.
