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

    Value Description
