Limiting the Property Sheet Display

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

To 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"));
           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;
   }
   

5. Build.

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