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;

Elements

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

EXTCONN_WEAK
