MONCBSTRUCT structure (ddeml.h)
Contains information about the current Dynamic Data Exchange (DDE) transaction. A DDE debugging application can use this structure when monitoring transactions that the system passes to the DDE callback functions of other applications.
Syntax
typedef struct tagMONCBSTRUCT {
UINT cb;
DWORD dwTime;
HANDLE hTask;
DWORD dwRet;
UINT wType;
UINT wFmt;
HCONV hConv;
HSZ hsz1;
HSZ hsz2;
HDDEDATA hData;
ULONG_PTR dwData1;
ULONG_PTR dwData2;
CONVCONTEXT cc;
DWORD cbData;
DWORD Data[8];
} MONCBSTRUCT, *PMONCBSTRUCT;
Members
cb
Type: UINT
The structure's size, in bytes.
dwTime
Type: DWORD
The Windows time at which the transaction occurred. Windows time is the number of milliseconds that have elapsed since the system was booted.
hTask
Type: HANDLE
A handle to the task (application instance) containing the DDE callback function that received the transaction.
dwRet
Type: DWORD
The value returned by the DDE callback function that processed the transaction.
wType
Type: UINT
The transaction type.
wFmt
Type: UINT
The format of the data exchanged (if any) during the transaction.
hConv
Type: HCONV
A handle to the conversation in which the transaction took place.
hsz1
Type: HSZ
A handle to a string.
hsz2
Type: HSZ
A handle to a string.
hData
Type: HDDEDATA
A handle to the data exchanged (if any) during the transaction.
dwData1
Type: ULONG_PTR
Additional data.
dwData2
Type: ULONG_PTR
Additional data.
cc
Type: CONVCONTEXT
The language information used to share data in different languages.
cbData
Type: DWORD
The amount, in bytes, of data being passed with the transaction. This value can be more than 32 bytes.
Data[8]
Type: DWORD[8]
Contains the first 32 bytes of data being passed with the transaction (8 * sizeof(DWORD)).
