Overview

The MONCBSTRUCT structure contains information about the current Dynamic Data Exchange (DDE) transaction. A DDE debugging App can use this structure when monitoring transactions that the system passes to the DDE callback functions of other Apps.

Typedef

struct { 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 } MONCBSTRUCT;

cb

Specifies the structure’s size, in bytes.

dwTime

Specifies the Windows time at which the transaction occurred. Windows time is the number of milliseconds that have elapsed since the system was booted.

hTask

Handle to the task (app instance) containing the DDE callback function that received the transaction.

dwRet

Specifies the value returned by the DDE callback function that processed the transaction.

wType

Specifies the transaction type.

wFmt

Specifies the format of the data exchanged (if any) during the transaction.

hConv

Handle to the conversation in which the transaction took place.

hsz1

Handle to a string.

hsz2

Handle to a string.

hData

Handle to the data exchanged (if any) during the transaction.

dwData1

Specifies additional data.

dwData2

Specifies additional data.

cc

Specifies a CONVCONTEXT structure containing language information used to share data in different languages.

cbData

Specifies the amount, in bytes, of data being passed with the transaction. This value can be more than 32 bytes.

Data

Contains the first 32 bytes of data being passed with the transaction (8 * sizeof(DWORD)).
