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:

Value	Meaning
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.
