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.

transactionType - uType - The transaction type.

dataFormat - uFmt - The format of the data sent from the server.

hconv - A handle to the conversation.

topic - hsz1 - A handle to the topic name.

item - hsz2 - A handle to the item name.

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

Returns:

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.
