      void onMonitor(int transactionType, Ddeml.HDDEDATA hdata, int eventCode)

    • Method Detail

      • onMonitor

        void onMonitor(int transactionType,
                       Ddeml.HDDEDATA hdata,
                       int eventCode)
        A Dynamic Data Exchange (DDE) debugger's DDE callback function, DdeCallback, receives the XTYP_MONITOR transaction whenever a DDE event occurs in the system. To receive this transaction, an application must specify the APPCLASS_MONITOR value when it calls the DdeInitialize function.
        Parameters:
        transactionType - uType - The transaction type.
        hdata - A handle to a DDE object that contains information about the DDE event. The application should use the DdeAccessData function to obtain a pointer to the object.
        eventCode - dwData2 - The DDE event. This parameter can be one of the following values:
        ValueMeaning
        MF_CALLBACKS
        0x08000000
        The system sent a transaction to a DDE callback function. The DDE object contains a MONCBSTRUCT structure that provides information about the transaction.
        MF_CONV
        0x40000000
        A DDE conversation was established or terminated. The DDE object contains a MONCONVSTRUCT structure that provides information about the conversation.
        MF_ERRORS
        0x10000000
        A DDE error occurred. The DDE object contains a MONERRSTRUCT structure that provides information about the error.
        MF_HSZ_INFO
        0x01000000
        A DDE application created, freed, or incremented the usage count of a string handle, or a string handle was freed as a result of a call to the DdeUninitialize function. The DDE object contains a MONHSZSTRUCT structure that provides information about the string handle.
        MF_LINKS
        0x20000000
        A DDE application started or stopped an advise loop. The DDE object contains a MONLINKSTRUCT structure that provides information about the advise loop.
        MF_POSTMSGS
        0x04000000
        The system or an application posted a DDE message. The DDE object contains a MONMSGSTRUCT structure that provides information about the message.
        MF_SENDMSGS
        0x02000000
        The system or an application sent a DDE message. The DDE object contains a MONMSGSTRUCT structure that provides information about the message.
