    How to receive MMS

    Hi all,
    it is my first program in symbian and I am working in a project which requires monitoring the incoming MMS & checks if it is an audio MMs or not but when i begin to define the class I have errors and I do not know how to treat them ;plz help me
    here the class :
    #ifndef CRECIEVE_H_
    #define CRECIEVE_H_

    #include <e32base.h>
    #include <msvapi.h> // MMsvSessionObserver
    #include <msvids.h>
    #include <msvapi.h>
    #include <msventry.h>
    #include <e32cmn.h>
    #include <mmsconst.h>

    class Crecieve : public CActive, public MMsvSessionObserver
    {
    public:
    CMsvSession* iSession;
    CMsvEntry *iMsvEntry;
    TMsvId iNewMessageId;
    virtual ~Crecieve();
    void HandleSessionEventL(TMsvSessionEvent, TAny*, TAny*, TAny*);
    void ProcessMMS();
    static Crecieve* NewL();
    static Crecieve* NewLC();
    protected:
    void ConstructL();
    Crecieve();
    virtual void DoCancel();
    };
    Crecieve::Crecieve()
    : CActive(EPriorityStandard) { CActiveScheduler::Add(this); }
    Crecieve* Crecieve::NewLC()
    {
    Crecieve* me = new (ELeave) Crecieve(); // First phase construction
    CleanupStack::PushL(me);
    me->ConstructL(); // Second phase construction
    return (me);
    };
    Crecieve* Crecieve::NewL()
    {
    Crecieve* me = Crecieve::NewLC();
    CleanupStack::Pop(me);
    return (me);
    };
    void Crecieve::ConstructL()
    {
    // Create CMsvSession asynchronously
    iSession = CMsvSession::OpenAsyncL(*this);
    }
    void Crecieve::HandleSessionEventL(TMsvSessionEvent aEvent, TAny* aArg1, TAny* aArg2, TAny* aArg3)
    {
    switch (aEvent)
    {
    case EMsvEntriesChanged:

    //reading the SMS here into a rich text object , after its entry has been finally created
    if (*(static_cast<TMsvId*>(aArg2)) == KMsvGlobalInBoxIndexEntryId)
    {
    CMsvEntrySelection* entries = static_cast<CMsvEntrySelection*>(aArg1);
    if (iNewMessageId == entries->At(0))
    {
    // Set entry context to the new message
    iMsvEntry=iSession->GetEntryL(iNewMessageId);
    if(iMsvEntry->Entry().iMtm == KUidMsgTypeMultimedia)
    Crecieve::ProcessMMS();
    iSession->RemoveEntry(iNewMessageId);
    }

    }
    break;


    default:
    // do nothing
    break;
    }
    };
    void Crecieve::ProcessMMS()
    (

    )
    void Crecieve:oCancel()
    {
    iSession.Close()
    }
    }
    #endif /*CRECIEVE_H_*/

    Re: How to receive MMS

    What kind of errors do you get?
    Note that the language is C++, thus it is preferable having the declaration in a .h file, and the definition in a separate .cpp file (having the method definitions in the header-file can lead to ambiguity-errors if you #include your header in multiple locations).
