Hi,

I trapped message for handling double click on Day Mode. My code is as follows:

In constructor of my Calendar View

CXTPNotifyConnection* ptrCalendarConn = GetCalendarCtrl().GetConnection();
    ASSERT(ptrCalendarConn);
   if(!ptrCalendarConn)
   {
        return;
    }

//To Trapp the DBLCLK on Calendar
   m_Sink.Advise(ptrCalendarConn, XTP_NC_CALENDARLBUTTONDBLCLICK, &CCalViewNew::OnEvent_Calendar);

void CMyViewNew::OnEvent_Calendar(XTP_NOTIFY_CODE Event, WPARAM wParam, LPARAM lParam)
{
    I am displaying my own dialog here for taking input data
}

I am getting CRASH at following location
XTPNotifyConnection.cpp

BOOL CXTPNotifyConnection::SendEvent(XTP_NOTIFY_CODE Event,
                                WPARAM wParam , LPARAM lParam, DWORD dwFlags)
{
    /* CRASH HERE*/
        catch(...)
        {
            ASSERT(FALSE);
            TRACE(_T("EXCEPTION! CXTPNotifyConnection::SendEvent(Event                         = %d, wParam = %d, lParam = %d, dwFlags = %x)\n"),
                    Event, wParam, lParam, dwFlags);
        }

}

Last call from my code before crash is:

pMyTemplate->InitialUpdateFrame(pMyFrame, pMyDocument, bMakeVisible);

Can you please advise.

Can anybody please suggest the solution?

Here is the call stack where it crashes on double clicking on Day View

Hi,

Have you initialized COM in the beginning?


BOOL CCalendarDemoApp::InitInstance()
{
    VERIFY( AfxOleInit() );

Hi,

Yes, I initialized COM at the beginning of my application.

if (!AfxOleInit())
{
return FALSE;
}

Still I am getting same error. Any solution?

Hello,

try to add

m_Sink.UnadviseAll();

to your view destructor.

Try to comment your code inside CMyViewNew::OnEvent_Calendar to determine where problem is.

If problem still occur - this means that we have bad ptrSink pointer. Try to look in the debugger what is the object pointed by ptrSink. It looks like some object call Advise but does not call Unadvise when destroyed.

Hi,

Here is the location of Crash:

XTPNotifyConnection.cpp

BOOL CXTPNotifyConnection::SendEvent(XTP_NOTIFY_CODE Event, WPARAM wParam , LPARAM lParam, DWORD dwFlags)

Line:-
catch(...)
{
ASSERT(FALSE);
TRACE(_T("EXCEPTION! CXTPNotifyConnection::SendEvent(Event = %d, wParam = %d, lParam = %d, dwFlags = %x)\n"),
Event, wParam, lParam, dwFlags);
}

Event = 10634

Here is the call Stack:-
