Re: Not receiving implemented events.

Thanks Igor. I've tried this - the results are puzzling. The program
flow falls into the following Advise function when the VB test app
starts up.
[code]
template <class T, const IID* piid, class CDV>
STDMETHODIMP IConnectionPointImpl<T, piid, CDV>::Advise(IUnknown*
pUnkSink,
    DWORD* pdwCookie)
{
    T* pT = static_cast<T*>(this);
    IUnknown* p;
    HRESULT hRes = S_OK;
    if (pdwCookie != NULL)
        *pdwCookie = 0;
    if (pUnkSink == NULL || pdwCookie == NULL)
        return E_POINTER;
    IID iid;
    GetConnectionInterface(&iid);
    hRes = pUnkSink->QueryInterface(iid, (void**)&p);
    if (SUCCEEDED(hRes))
    {
        pT->Lock();
        *pdwCookie = m_vec.Add(p);
        hRes = (*pdwCookie != NULL) ? S_OK : CONNECT_E_ADVISELIMIT;
        pT->Unlock();
        if (hRes != S_OK)
            p->Release();
    }
    else if (hRes == E_NOINTERFACE)
        hRes = CONNECT_E_CANNOTCONNECT;
    if (FAILED(hRes))
        *pdwCookie = 0;
    return hRes;
}
[/code]

I can see that the QueryInterface is successful and the m_vec.Add(p)
call successfully adds the interface to the vector map. Nothing else
seems to happen until I make the test call into the server, which
calls the event Fire_ method. At this point the m_vec map is empty and
contains no interface pointers! Do you know of any way this vector
could be cleared down? Is there somewhere else I can break in to get a
clearer view of where it might be happening. Your help so far has been
great.

BTW Alexander:
I assume you are referring to the following, which does seem to be
correctly in the connection map.

    BEGIN_CONNECTION_POINT_MAP(CCoMessageEventTest)
                ...
        CONNECTION_POINT_ENTRY(__uuidof(DThirdPartyEvents))
    END_CONNECTION_POINT_MAP()

As a matter of interest, by source dispinterface, I assume you are
referring to the Event interface I have implemented (not any interface
local/specific to the server.)
