FIX: Interfaces Not Released by _com_ptr_t::CreateInstance()

MORE INFORMATION

HRESULT hr = CoCreateInstance(..., ..., IID_IUnknown, (LPVOID*)&pUnk);
if (FAILED(hr))
    //Do error handling.

hr = OleRun(pUnk);

if (FAILED(hr)) {
    pUnk->Release();
    //Do error handling
}

// Query for the required interface, such as IFoo.
hr = pUnk->QueryInterface( IID_IFoo, pFoo);

if (FAILED(hr)) {
    pUnk->Release();
    //Do error handling
}
				

// Declare the smart pointer for the IFoo interface.
IFooPtr m_pFoo;

// Attach the raw interface pointer which you got above
// to the smart pointer wrapper.
m_pFoo.Attach(pFoo);
