      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.
