IMAPIAdviseSink Problem

Hey.
I have the following code:
Header;

Code:

---

#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;
};

When i attempt to compile it i get:

Code:

---

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

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:

Code:

---

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.
