vld memory profiler informed about 40 bytes memory leak in this trace... is there any "fast" way to solve this?

Thx.

Yes, the IDE shows and 'unknown' leak, and the memory profiler indicates that that leak is produced from calendar.

Nop, but the main difference between your sample and my app is that in your sample you use MDI (or SDI) and I dont embebe the calendar control in any window because I'm just using the sheduler part (OnReminders). So I derive a class from your CXTPCalendarControl class and just declare a object of this class.

Sorry for the long sheet of code.

//File CCalendar.h

class CCalendar : public CXTPCalendarControl
{
public:
CCalendar();
virtual ~CCalendar();
DECLARE_DYNCREATE(CCalendar);
bool StartSchedule();
...
protected:
DECLARE_XTP_SINK(CCalendar, m_Sink);
void OnReminders(XTP_NOTIFY_CODE Event, WPARAM wParam , LPARAM lParam);
...
};

//File CCalendar.cpp
IMPLEMENT_DYNCREATE(CCalendar, CXTPCalendarControlView)

void CCalendar::OnReminders(XTP_NOTIFY_CODE Event, WPARAM wParam , LPARAM lParam)
{
UNREFERENCED_PARAMETER(lParam);

int eAction = (int)wParam;

switch (eAction)
{
case xtpCalendarRemindersFire:
  {
   CXTPCalendarRemindersManager *calRemindersManager = GetRemindersManager();
   CXTPCalendarReminders calRemindersL;
   CXTPCalendarReminder *pcalReminder;
   CXTPCalendarEventPtr cEvent;
   XTP_CALENDAR_RECURRENCE_OPTIONS cOptions;

calRemindersManager->GetActiveReminders(calRemindersL);

   for (int i = 0; i < calRemindersL.GetCount(); i++)
   {
    pcalReminder = calRemindersL.GetAt(i);
    cEvent = pcalReminder->GetEvent();
    //get some event atributes
    pcalReminder->Dismiss();
   }
   ::SendMessage(parentInstance, WM_CAL_SHEDULER, 0, 0);
  }
  break;
case xtpCalendarReminderDismissed:
case xtpCalendarReminderDismissedAll:
case xtpCalendarRemindersMonitoringStarted:
case xtpCalendarRemindersMonitoringStopped:
default:
     break;
}
}

bool CCalendar::StartSchedule()
{
CXTPCalendarData* data = GetDataProvider();
CXTPCalendarEventsPtr cEvents = data->RetrieveDayEvents(COleDateTime::GetCurrentTime());
CXTPCalendarEventPtr p;
for (int i = 0; i < cEvents->GetCount(); i++)
{
p = cEvents->GetAt(i, TRUE);

//get some events data
}
cEvents->RemoveAll();
EnableReminders(true);
::SendMessage(parentInstance, WM_CAL_SHEDULER, 0, 0);
CConfig::SetCalendar(true);
return true;
}

//Main
CCalendar calendar;
calendar.StartSchedule();

Hi,

Problem that CXTPCalendarControl has own sink and think its main reason.

Try change it to

class CCalendar

{
public:
bool StartSchedule();
...
protected:
DECLARE_XTP_SINK(CCalendar, m_Sink);
void OnReminders(XTP_NOTIFY_CODE Event, WPARAM wParam , LPARAM lParam);
...

CXTPCalendarControl m_wndCalendar

};

It worked perfect, no leaks, working correct. Thanks for your help oleg. Great job.

Mmm.. I've just realized that I'm in AX forums, not MFC. srry.
