Hi All,
Is anyone familiar with the EDB notification mechanism? I have some code that has opened the appointments database to get change notifications, all well and good. The trouble is I am unable to delete the CENOTIFICATION structure, meaning I get a memory leak after every change.
if anyone has seen this or knows the solution, I'd be grateful.
CEOID apps_oid;
request= new CENOTIFYREQUEST; // or (CENOTIFYREQUEST *) LocalAlloc (LPTR,
// sizeof (CENOTIFYREQUEST));
if (request) {
request->dwSize = sizeof (CENOTIFYREQUEST);
request->hwnd = hwnd;
request->hHeap = NULL;
request->dwFlags = CEDB_EXNOTIFICATION;
request->dwParam = param;
database = CeOpenDatabaseInSession ( NULL,
&pim_guid,
&apps_oid,
L"Appointments Database",
0,
0, // or CEDB_AUTOINCREMENT,
request);
}
. . .
case WM_DBNOTIFICATION:
{
CENOTIFICATION * notification = (CENOTIFICATION *)lParam;
// Always returns FALSE
BOOL hr = CeFreeNotification(request, notification);
// Always returns 5 - access denied
DWORD dw = GetLastError();
}
break;
