XTYP_CONNECT_CONFIRM transaction

A Dynamic Data Exchange (DDE) server callback function, DdeCallback, receives the XTYP_CONNECT_CONFIRM transaction to confirm that a conversation has been established with a client and to provide the server with the conversation handle. The system sends this transaction as a result of a previous XTYP_CONNECT or XTYP_WILDCONNECT transaction.

#define XTYPF_NOBLOCK 0x0002
#define XCLASS_NOTIFICATION 0x8000
#define XTYP_CONNECT_CONFIRM (0x0070 | XCLASS_NOTIFICATION | XTYPF_NOBLOCK)

A server cannot block this transaction type; the CBR_BLOCK return code is ignored.
