Limiting the Property Sheet Display

The property sheet should display only on the relevant application filter.

Ff827439.wedge(en-us,VS.85).gifTo limit the property sheet display

  1. Select a unique name for the application filter; for example, its GUID.

  2. Add the folder containing the file Msfpccom.dll (<SDK installation root>\bin) to the include path.

  3. In Stdafx.h add the following #import statement:

    #import "msfpccom.dll" named_guids

    The #import directive is used to incorporate information from a type library. The content of the type library is converted into C++ classes, mostly describing the COM interfaces.

  4. In the .cpp file where your snap-in is defined, add the if statement in the following example code to the method that creates property pages and change the GUID to the GUID of your application filter:

    HRESULT CFilterSnapInExtData::CreatePropertyPages(LPPROPERTYSHEETCALLBACK lpProvider,
        long handle, 
        IUnknown* pUnk,
        DATA_OBJECT_TYPES type)
        FPCLib::IFPCSnapinNodePtr spiSnapinNode(m_pDataObject);
        FPCLib::IFPCApplicationFilterPtr spiApplicationFilter(spiSnapinNode->CurrentObject);
        _bstr_t bstrGUID(spiApplicationFilter->get_Guid());
        // if (type == CCT_SCOPE || type == CCT_RESULT) 
        if (bstrGUID == _bstr_t("{7CCF6FF0-D995-4da1-B452-4228047B2D1D}"))  // Filter GUID
            CFilterSnapInPage* pPage = new CFilterSnapInPage(handle, true, _T("FilterSnapIn"));
            // 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;
  5. Build.

  6. Test. Run Forefront TMG Management. Notice that the property sheet appears only on the appropriate filter.
