Rebonjour,

J'ai trouvé un example de code pour les évènements que je veux récupérer sur MSDN. Voici ce code :

//
// Example 1: Implement a simple event handler.
//
HRESULT STDMETHODCALLTYPE
CTAPIEventNotification::Event(
    TAPI_EVENT  TapiEvent,
    IDispatch * pEvent
    )
{
    // AddRef the event so it does not go away.
    pEvent->AddRef();
 
    // Post a message to our own UI thread.
    BOOL bMessage;
    bMessage = PostMessage( 
                           ghDlg,
                           WM_PRIVATETAPIEVENT,
                           (WPARAM) TapiEvent,
                           (LPARAM) pEvent
                           );
    // If (bMessage == 0) process the error here. 
    return S_OK;
}
 
//
// Example 2: Register the event interface.
//
long                         gulAdvise;  // Globally declared
IConnectionPointContainer   * pCPC;
IConnectionPoint            * pCP;
IUnknown                    * pUnk;
 
// Get the connection point container
// interface pointer from the TAPI object.
hr = gpTapi->QueryInterface(
        IID_IConnectionPointContainer,
        (void **)&pCPC
        );
// If ( hr != S_OK O) process the error here. 
 
// Get the ITTAPIEventNotification interface
// pointer from the container.
hr = pCPC->FindConnectionPoint(
        IID_ITTAPIEventNotification,
        &pCP
        );
// If ( hr != S_OK O) process the error here. 
 
pCPC->Release();
 
// Create a private event notification object.
pTapiEventNotification = new CTAPIEventNotification;
 
hr = pTAPIEventNotification->QueryInterface(
        IID_IUnknown,
        (void **)&pUnk
        );
// If ( hr != S_OK O) process the error here. 
 
// Call the advise method to give TAPI
// the IUnknown pointer for the event handler.
hr = pCP->Advise(
        pUnk,
        (ULONG *)&gulAdvise
        );
// If ( hr != S_OK O) process the error here. 
 
pCP->Release();
 
//
// Example 3: Set the event filter.
//
// Assume we are interested
// only in call-related events.
hr = gpTapi->put_EventFilter(
   TE_CALLNOTIFICATION | TE_CALLSTATE | TE_CALLMEDIA
   );
// If ( hr != S_OK O) process the error here. 
 
//
// Example 4: Register an address with TAPI
// for call notifications. Assume we are interested
// in video and audio calls, and that pAddress
// is a pointer to the ITAddress interface of
// an address that can handle both media types.
 
long glRegister; // Globally declared
 
hr = gpTapi->RegisterCallNotifications(
    pAddress,
    VARIANT_TRUE,   // monitor privileges
    VARIANT_TRUE,   // owner privileges
    TAPIMEDIATYPE_AUDIO|TAPIMEDIATYPE_VIDEO,
    gulAdvise,      // As returned by Advise
    &glRegister
    );
// If ( hr != S_OK O) process the error here.
Comment incorporer la classe présentée au point 1 dans mon programme ?

Est ce que quelqu'un peut me donner une idée ?

Merci d'avance
