IMAPIAdviseSink Problem

[Quell]

Hey.
I have the following code:
Header;

#pragma once
#include <cemapi.h>
#include <mapiutil.h>
#include <mapidefs.h>

class CIMAPIAdviseSink : public IMAPIAdviseSink
{
public:
CIMAPIAdviseSink(void);
virtual ~CIMAPIAdviseSink();

STDMETHODIMP QueryInterface(REFIID riid, LPVOID * ppvObj);
STDMETHODIMP_(ULONG) AddRef();
STDMETHODIMP_(ULONG) Release();

STDMETHODIMP_(ULONG) OnNotify (ULONG cNotify, LPNOTIFICATION lpNotifications);

private :
LONG m_cRef;
};


Source

#include "StdAfx.h"
#include "CustomImapi.h"

CIMAPIAdviseSink::CIMAPIAdviseSink(void)
{
}
CIMAPIAdviseSink::~CIMAPIAdviseSink()
{
};


STDMETHODIMP CIMAPIAdviseSink::QueryInterface(REFIID riid, LPVOID * ppvObj)
{
*ppvObj = 0;
if (riid == IID_IMAPIAdviseSink || riid == IID_IUnknown)
{
*ppvObj = (LPVOID)this;
AddRef();
return S_OK;
}
return E_NOINTERFACE;
};

STDMETHODIMP_(ULONG) CIMAPIAdviseSink::AddRef()
{
LONG lCount = InterlockedIncrement(&m_cRef);
return lCount;
};

STDMETHODIMP_(ULONG) CIMAPIAdviseSink::Release()
{
LONG lCount = InterlockedDecrement(&m_cRef);
if (!lCount) delete this;
return lCount;
};

STDMETHODIMP_(ULONG) CIMAPIAdviseSink::OnNotify (ULONG cNotify, LPNOTIFICATION lpNotifications)
{
HRESULT hRes = S_OK;


try
{
for (ULONG i=0 ; i<cNotify ; i++)
{
hRes = S_OK;
if (fnevNewMail == lpNotifications[i].ulEventType)
{
}
else if (fnevTableModified == lpNotifications[i].ulEventType)
{
switch(lpNotifications[i].info.tab.ulTableEvent)
{
case(TABLE_ERROR):
case(TABLE_CHANGED):
case(TABLE_RELOAD):
//EC_H((HRESULT)::SendMessage(m_hWndParent,WM_MFCMAPI_REFRESHTABLE,(WPARAM) m_hTreeParent,0));

break;
}
}
}
}
catch(...)

/*ErrDialog(__FILE__,__LINE__,
_T("Exception encountered in CAdviseSink."));*/
}
return 0;
}


When i attempt to compile it i get:

error LNK2001: unresolved external symbol IID_IMAPIAdviseSink

Any ideas why? I get go to the definition of the GUID easily.
I included cemapi.lib in the linker options (Smart Device Deploymnet), but i got no idea why i am getting that error.
Thx in advance.

Okey,
I think i figured out the compilation error. I forgot a definition before the object. However i am still having some problems with the code

#define INITGUID
#define USES_IID_IMAPIAdviseSink
#include <initguid.h>
#include <MAPIguid.h>
#include <cemapi.h>
class CMapiAdviseSink : public IMAPIAdviseSink
{
protected:
LPNOTIFCALLBACK m_pfnCallback;
LPVOID m_lpvContext;
LONG m_cRef;

public:
CMapiAdviseSink( LPNOTIFCALLBACK pfnCallback, LPVOID lpvContext )
: m_pfnCallback( pfnCallback )
, m_lpvContext( lpvContext )
, m_cRef( 0 )
{
}

public:// IUnknown
STDMETHOD(QueryInterface)( REFIID riid, LPVOID FAR * ppvObj )
{
if( IID_IUnknown == riid || IID_IMAPIAdviseSink == riid )
{
*ppvObj = this;
AddRef();
return S_OK;
}
return E_NOINTERFACE;
}
STDMETHOD_(ULONG, AddRef)()
{
return InterlockedIncrement( &m_cRef );
}
STDMETHOD_(ULONG, Release)()
{
ULONG ul = InterlockedDecrement( &m_cRef );

if( 0 == ul )
delete this;

return ul;
}

public:// IMAPIAdviseSink
STDMETHOD_(ULONG, OnNotify)( ULONG cNotif,
LPNOTIFICATION lpNotifications )
{
if( m_pfnCallback )
m_pfnCallback( m_lpvContext, cNotif, lpNotifications );

return S_OK;
}
};
STDAPI HrAllocAdviseSink( LPNOTIFCALLBACK lpfnCallback, LPVOID lpvContext, LPMAPIADVISESINK* lppAdviseSink )
{
if( NULL == lppAdviseSink )
return E_INVALIDARG;

*lppAdviseSink = new CMapiAdviseSink( lpfnCallback, lpvContext );

if( NULL == *lppAdviseSink )
return E_OUTOFMEMORY;

(*lppAdviseSink)->AddRef();
return S_OK;
}
ULONG __stdcall CallBack (LPVOID lpvContext, ULONG cNotification, LPNOTIFICATION lpNotifications )
{
MessageBox(0,_T("tesT"),0,0);
return 0;
}


and use:

DWORD dwContext = 0;
CMapiAdviseSink *lppAdviseSink = new CMapiAdviseSink((LPNOTIFCALLBACK)&CallBack, &dwContext );
lppAdviseSink);
(*lppAdviseSink).AddRef();


Anyways, i tried getting any notifications but i am not breaking anywhere.
Note that htis is running on a Win Ce device, but this should be no different from a desktop environment:D
Any ideas where the mistake is?
Thx in advance.
