    if (type == CCT_SCOPE || type == CCT_RESULT)
    

    that is shown as a comment in the following code. This line appears several times in the code, so be certain to comment out the right line.

    HRESULT CSmtpFltrSnapInExtData::CreatePropertyPages(LPPROPERTYSHEETCALLBACK lpProvider,
    	long handle, 
    	IUnknown* pUnk,
    	DATA_OBJECT_TYPES type)
    {
    	// if (type == CCT_SCOPE || type == CCT_RESULT) 
    	{
    		CSmtpFltrSnapInPage* pPage = new CSmtpFltrSnapInPage(handle, true, _T("SmtpFltrSnapIn"));
    		lpProvider->AddPage(pPage->Create());
    		// The second parameter to the property page class constructor
    		// should be true for only one page.
     
    		// TODO : Add code here to add additional pages
    		return S_OK;
    }
    	return E_UNEXPECTED;
    }
    

13. In SmtpFltrSnapIn.h, in the CSmtpFltrSnapInExtData class, comment out the line shown as a comment in the following code:

    	STDMETHOD(QueryPagesFor)(DATA_OBJECT_TYPES type)
    	{
    		// if (type == CCT_SCOPE || type == CCT_RESULT) 
    			return S_OK;
    		return S_FALSE;
    }
