intercept sms

Hi to all

I want intercept the creation of an sms. I've read many examples so the solution is to use an observer: 

class CSmsEngine : public CBase, public MMsvSessionObserver
    {
    public:
      
        static CSmsEngine* NewL();
   ~CSmsEngine();

      void CreateLocalMessageL( TMsvId aFolderId, const TDesC& aAddress, const TDesC& aDescription, const TDesC& aMsgText );
       
    private:

        void ConstructL(); 
        // from MMsvSessionObserver
        void HandleSessionEventL( TMsvSessionEvent aEvent, TAny* aArg1, TAny* aArg2, TAny* aArg3 );

    private:
      
   // SMS client MTM interface
   CSmsClientMtm*      iSmsMtm;
   // Represents a session to the messaging server
        CMsvSession*        iSession;   

   // This registry holds details of the all the Client-side
   // MTMs currently available on the system.
        CClientMtmRegistry* iClientMtmReg;
       
        // The last "clone"
        TMsvId iLastChangedMessageId;

    };


void CSmsEngine::ConstructL()
    {
   // Connect to the Messaging server
   // Upon successful connection HandleSessionEventL (EMsvServerReady)
   // will be called
    iSession = CMsvSession::OpenSyncL( *this );   
   //iSession->AddObserverL(*this);

    iClientMtmReg = CClientMtmRegistry::NewL(*iSession);
    // Get the SMS Mtm client from the registry
    iSmsMtm = static_cast<CSmsClientMtm*>(
        iClientMtmReg->NewMtmL( KUidMsgTypeSMS ) );

    }

I want to use this class in an console program:

LOCAL_C void MainL(const TDesC& aArgs)
    {
 
   const TMsvId KInbox = KMsvGlobalInBoxIndexEntryId;

   CSmsEngine * iEngine = CSmsEngine::NewL();

   iEngine->CreateLocalMessageL( KInbox,
      _L("+3333333333"),
      _L("subject "),
      _L("body")
      );
       delete iEngine;
    }

Now the message is created but i can't intercept the creation because the callback HandleSessionEventL isn't called. Notice that the smsengine module works well in an .app program. Any suggestion?

thanks
