Limiting the Property Sheet Display

The property sheet should display only on the relevant application filter; in this case, on the SMTP application filter.

To limit the property sheet display

1. Select a unique attribute name for the application filter; for example, its GUID.
2. Add the directory of 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 SmtpFilterSnapIn.cpp, add the code that is in bold font in the following sample to this method:

   HRESULT CSMTPFltrSnapInExtData::CreatePropertyPages(LPPROPERTYSHEETCALLBACK lpProvider,
   	long handle, 
   	IUnknown* pUnk,
   	DATA_OBJECT_TYPES type)
   {
   	FPCLib::IFPCSnapinNodePtr spiFPCSnapinNode(m_pDataObject);
    
   	FPCLib::IFPCApplicationFilterPtr spiApplicationFilter(spiFPCSnapinNode->CurrentObject);
   
   	_bstr_t bstrGUID(spiApplicationFilter->GetGuid());
    
   	// if (type == CCT_SCOPE || type == CCT_RESULT) 
       if (bstrGUID == _bstr_t("{179A0A70-1EF5-11D3-B160-00A0C9E3F998}"))  // Smtp Filter GUID
   	{
   				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;
   }
   

5. Build.
6. Test. Run ISA Management. Notice that the property sheet appears only on the SMTP application filter.
