XTYP_POKE transaction

A client uses the XTYP_POKE transaction to send unsolicited data to the server. A Dynamic Data Exchange (DDE) server callback function, DdeCallback, receives this transaction when a client specifies XTYP_POKE in the DdeClientTransaction function.


#define     XCLASS_FLAGS             0x4000
#define     XTYP_POKE               (0x0090 | XCLASS_FLAGS         )

hdata

A handle to the data that the client is sending to the server.

dwData1

dwData2

Return value

A server callback function should return the DDE_FACK flag if it processes this transaction, the DDE_FBUSY flag if it is too busy to process this transaction, or the DDE_FNOTPROCESSED flag if it rejects this transaction.

Remarks

This transaction is filtered if the server application specified the CBF_FAIL_POKES flag in the DdeInitialize function.
