Re: Crash in Virtual destructor

We are already doing this, my mistake that I did not post the implementation
of other method (OnNOtify) in my earlier message,

--------------------
ULONG CCustomAdviseSink::OnNotify(ULONG cNotif, LPNOTIFICATION
lpNotifications)
{
    //do some stuff....
  HRESULT hr = m_lpOrigSink->OnNotify(cNotif, lpNotifications);

 
    return hr;
}
---------------------

The problem I see is in QueryInterface implementation

STDMETHODIMP CCustomAdviseSink::QueryInterface(REFIID riid, LPVOID * ppvObj)
{
    HRESULT hr = S_OK;
    *ppvObj = NULL;

    hr = m_lpOrigSink->QueryInterface(riid, ppvObj);
    if(*ppvObj == m_lpOrigSink)
        *ppvObj = (LPVOID)this;
    return hr;
}

For interface requests other than IMAPIAdviseSink we are in dark as we do
not have information on what interfaces they implement.

Or is my understanding is completely wrong here.

Thanks for your response.

Cheers,
