MONCONVSTRUCT structure (ddeml.h)

Contains information about a Dynamic Data Exchange (DDE) conversation. A DDE monitoring application can use this structure to obtain information about a conversation that has been established or has terminated.

Syntax

typedef struct tagMONCONVSTRUCT {
  UINT   cb;
  BOOL   fConnect;
  DWORD  dwTime;
  HANDLE hTask;
  HSZ    hszSvc;
  HSZ    hszTopic;
  HCONV  hConvClient;
  HCONV  hConvServer;
} MONCONVSTRUCT, *PMONCONVSTRUCT;

Members

cb

Type: UINT

The structure's size, in bytes.

fConnect

Type: BOOL

Indicates whether the conversation is currently established. A value of TRUE indicates the conversation is established; FALSE indicates it is not.

dwTime

Type: DWORD

The Windows time at which the conversation was established or terminated. Windows time is the number of milliseconds that have elapsed since the system was booted.

hTask

Type: HANDLE

A handle to a task (application instance) that is a partner in the conversation.

hszSvc

Type: HSZ

A handle to the service name on which the conversation is established.

hszTopic

Type: HSZ

A handle to the topic name on which the conversation is established.

hConvClient

Type: HCONV

A handle to the client conversation.

hConvServer

Type: HCONV

A handle to the server conversation.

Remarks

Because string handles are local to the process, the hszSvc and hszTopic members are global atoms. Similarly, conversation handles are local to the instance; therefore, the hConvClient and hConvServer members are window handles.

The hConvClient and hConvServer members of the MONCONVSTRUCT structure do not hold the same value as would be seen by the applications engaged in the conversation. Instead, they hold a globally unique pair of values that identify the conversation.
