MONLINKSTRUCT structure (ddeml.h)

Contains information about a Dynamic Data Exchange (DDE) advise loop. A DDE monitoring application can use this structure to obtain information about an advise loop that has started or ended.

Syntax

typedef struct tagMONLINKSTRUCT {
  UINT   cb;
  DWORD  dwTime;
  HANDLE hTask;
  BOOL   fEstablished;
  BOOL   fNoData;
  HSZ    hszSvc;
  HSZ    hszTopic;
  HSZ    hszItem;
  UINT   wFmt;
  BOOL   fServer;
  HCONV  hConvServer;
  HCONV  hConvClient;
} MONLINKSTRUCT, *PMONLINKSTRUCT;

Members

cb

Type: UINT

The structure's size, in bytes.

dwTime

Type: DWORD

The Windows time at which the advise loop was started or ended. 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 advise loop.

fEstablished

Type: BOOL

Indicates whether an advise loop was successfully established. A value of TRUE indicates an advise loop was established; FALSE indicates it was not.

fNoData

Type: BOOL

Indicates whether the XTYPF_NODATA flag is set for the advise loop. A value of TRUE indicates the flag is set; FALSE indicates it is not.

hszSvc

Type: HSZ

A handle to the service name of the server in the advise loop.

hszTopic

Type: HSZ

A handle to the topic name on which the advise loop is established.

hszItem

Type: HSZ

A handle to the item name that is the subject of the advise loop.

wFmt

Type: UINT

The format of the data exchanged (if any) during the advise loop.

fServer

Type: BOOL

Indicates whether the link notification came from the server. A value of TRUE indicates the notification came from the server; FALSE indicates otherwise.

hConvServer

Type: HCONV

A handle to the server conversation.

hConvClient

Type: HCONV

A handle to the client conversation.

Remarks

Because string handles are local to the process, the hszSvc, hszTopic, and hszItem members are global atoms.

The hConvClient and hConvServer members of the MONLINKSTRUCT 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.
