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
