Почему мои функции IWMPEvents никогда не вызываются?

У меня проблема с IWMPEvents, который я успешно советовал, но никогда не поднимал. Вот как я создаю кодировку Windows Media Player:

HRESULT MyWMP::setURL(wchar_t* url)
{
return pMediaPlayer->put_URL(url);   // Load and play songs successfully;
}

bool MyWMP::CreatePlayer()
{
HRESULT hr;
const CLSID CLSID_WindowsMediaPlayer = { 0x6BF52A52, 0x394A, 0x11d3,{ 0xB1, 0x53, 0x00, 0xC0, 0x4F, 0x79, 0xFA, 0xA6 } };
hr = ::OleCreate(CLSID_WindowsMediaPlayer, IID_IOleObject, OLERENDER_DRAW, 0, this, this, (void**)&oleObject);
if (SUCCEEDED(hr) && oleObject)
{
if (SUCCEEDED(hr)) hr = oleObject->SetClientSite(this);
if (SUCCEEDED(hr)) hr = OleSetContainedObject(oleObject, TRUE);

if (SUCCEEDED(hr))
{
RECT posRect;
::SetRect(&posRect, -300, -300, 300, 300);
hr = oleObject->DoVerb(OLEIVERB_INPLACEACTIVATE, NULL, this, -1, this->hwnd, &posRect);
}
hr = oleObject->QueryInterface(&pMediaPlayer);
}
if (FAILED(hr) || !pMediaPlayer)
{
MessageBox(NULL, L"Create Browser failed!", L"Error", MB_ICONERROR);
return false;
}
return true;
}

MyWMP::MyWMP(HWND parentHWND, HINSTANCE hInstance) :
isFullyCreated(false)
{
OleInitialize(NULL);
HRESULT hr = E_FAIL;
IConnectionPointContainer* container = nullptr;
IUnknown* punk = nullptr;

this->parentHWND = parentHWND;
this->hwnd = CreateWindow(L"Static", NULL, WS_CHILD | WS_VISIBLE, 221, 0, 300, 300, parentHWND, NULL, hInstance, 0);

iComRefCount = 0;
::SetRect(&rObject, 0, 0, 300, 300);

if (CreatePlayer())
{
hr = pMediaPlayer->get_settings(&pMediaPlayerSettings);
if (SUCCEEDED(hr) && pMediaPlayerSettings)
{
pMediaPlayerSettings->put_autoStart(VARIANT_TRUE);
pMediaPlayerSettings->put_volume(100);
}
hr = pMediaPlayer->QueryInterface(IID_IConnectionPointContainer, (void**)&container);
if (SUCCEEDED(hr) && container) hr = container->FindConnectionPoint(__uuidof(IWMPEvents), &callback);
if (FAILED(hr) && container)
{
hr = container->FindConnectionPoint(__uuidof(_WMPOCXEvents), &callback);
}
if (SUCCEEDED(hr) && callback)
{
CWMPEventDispatch *cw = new CWMPEventDispatch();
IUnknown *cwUnk = NULL;
if (SUCCEEDED(cw->QueryInterface(IID_IUnknown, (void**)&cwUnk)))
{
if (SUCCEEDED(hr) && container)
{
hr = callback->Advise(cwUnk, &eventCookie);
if (SUCCEEDED(hr) && eventCookie)
{
isFullyCreated = true; // Set breakpoint here and is triggered
// by debugger
// hr = S_OK
}
}
}
if (cwUnk) cwUnk->Release();
}
if (punk) punk->Release();
if (container) container->Release();
}
}

Сильфон это CWMPEventDispatch учебный класс. Я установил точку останова на всех IDispatch функции и ни одна из них не запускается отладчиком. Когда я загружаю новые песни, играю / пауза (на встроенных кнопках управления пользовательского интерфейса), эти функции никогда не вызывается.

Почему мой IWMPEvents функции никогда не вызываются, и как это исправить?
