catch ATL COM event in MFC app

Hi,

I have a ATL COM object which fire event through connection point. I
want to catch the event in my MFC application and handle it. I followed
the MSDN aticle to do this. But I got compiling error says
"error C2146: syntax error : missing ';' before identifier
'DISP_FUNCTION_ID'
fatal error C1004: unexpected end of file found

http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/q181/8/45.asp&NoWebContent=1

Can anyone tell me what's wrong? I am new to these. Do I need to do
something, say add the .idl file to the MFC project before I following
the instructions in the article? Here is some of my code...

//idl file
........
library THUMBSCBLib
{
    importlib("stdole32.tlb");
    importlib("stdole2.tlb");

    [
        uuid(E381D6C4-3E26-4d02-A360-22BCC0399E98),
        helpstring("_IExtractEvent Interface")
    ]
    dispinterface _IExtractEvent
    {
        properties:
        methods:
        [id(1), helpstring("method OnExtractImage")] HRESULT
OnExtractImage([in, out] LONG *pHBmpThumbnail );
    };

    [
        uuid(B3A3E4E4-08BE-4ad2-9333-E8958FA1E00D),
        helpstring("IconExtractor Class")
    ]
    coclass ScribbleExtractor
    {
        [default] interface IScribbleExtractor;
        [default, source] dispinterface _IExtractEvent;
    };
};

// CEventSink file
IMPLEMENT_DYNCREATE(CEventSink, CCmdTarget)

CEventSink::CEventSink()
{
    EnableAutomation();
}

CEventSink::~CEventSink()
{
}

void CEventSink::OnFinalRelease()
{
    // When the last reference for an automation object is released
    // OnFinalRelease is called. The base class will automatically
    // deletes the object. Add additional cleanup required for your
    // object before calling the base class.

    CCmdTarget::OnFinalRelease();
}

BEGIN_MESSAGE_MAP(CEventSink, CCmdTarget)
    //{{AFX_MSG_MAP(CEventSink)
        // NOTE - the ClassWizard will add and remove mapping macros here.
    //}}AFX_MSG_MAP
END_MESSAGE_MAP()

BEGIN_DISPATCH_MAP(CEventSink, CCmdTarget)
    //{{AFX_DISPATCH_MAP(CEventSink)
        // NOTE - the ClassWizard will add and remove mapping macros here.
    DISP_FUNCTION_ID(CEventSink,"ExtractThumbnail",1,OnExtractImage,VT_I4,VT_BYREF|VT_I4)
// DISP_FUNCTION_ID(CMySink,"ExtractThumbnail",1,OnExtractImage,VTS_I4,VTS_I4)
    //}}AFX_DISPATCH_MAP
END_DISPATCH_MAP()

// from VBA. This IID must match the GUID that is attached to the
// dispinterface in the .ODL file.
