1/6/2010

This structure contains information to initialize the database and object store notification process. This structure is passed to the CeOpenDatabaseEx2 (CEDB) or the CeRegisterReplNotification function to initiate the process.

Syntax

typedef struct _CENOTIFYREQUEST {
  DWORD dwSize;
  HWND hwnd; 
  DWORD dwFlags;
  HANDLE hHeap;
  DWORD dwParam;
} CENOTIFYREQUEST; 

Members

• dwSize
  Size of the CENOTIFYREQUEST structure.

• hwnd
  Handle to the window that receives notifications.

• dwFlags
  Notification handling mode. The following table shows possible values.

  Value	Description
  CEDB_EXNOTIFICATION	Request to receive a pointer to a CENOTIFICATION (CEDB) structure that identifies which objects have changed. Applications working with mounted database volumes must set this flag to receive proper notification of changes in a volume.

• hHeap
  Handle to a heap that is used to allocate the notification structure. If this is set to NULL, the system allocates memory in the default heap of the process.
