- ## Method Details

  - ### onPoke

    int onPoke(int transactionType, int dataFormat, Ddeml.HCONV hconv, Ddeml.HSZ topic, Ddeml.HSZ item, Ddeml.HDDEDATA hdata)
    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.
    Parameters:
      `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.
