Getting data from a connection point (event)

I am trying to implement a connection point / event to get data.

The method is defined in my IDL as follows:

[id(4), helpstring("method InquireAbort")] HRESULT InquireAbort([in]
VARIANT_BOOL *Abort);

The wizard produces the code below with the exception of this line:

avarParams[0] = Abort; avarParams[0].vt = VT_PTR;

the wizard actually produces this code:

avarParams[0] = Abort; avarParams[0].vt = VT_PBOOL

but VT_PBOOL does not seem to be defined anywhere so I changed it to VT_PTR

But I still cannot obtain a the value that is set.

if I call Fire_InquireAbort, abort still stays to false even though the
client application is setting it to true.

VARIANT_BOOL abort=0;
m_gpsObj->Fire_InquireAbort(&abort);

What am I doing wrong?

HRESULT Fire_InquireAbort( VARIANT_BOOL * Abort)
{
HRESULT hr = S_OK;
T * pThis = static_cast<T *>(this);
int cConnections = m_vec.GetSize();

for (int iConnection = 0; iConnection < cConnections; iConnection++)
{
    pThis->Lock();
    CComPtr<IUnknown> punkConnection = m_vec.GetAt(iConnection);
    pThis->Unlock();
    IDispatch * pConnection = static_cast<IDispatch *>(punkConnection.p);

    if (pConnection)
    {
        CComVariant avarParams[1];
        avarParams[0] = Abort; avarParams[0].vt = VT_PTR;
        CComVariant varResult;

        DISPPARAMS params = { avarParams, NULL, 1, 0 };
        hr = pConnection->Invoke(4, IID_NULL, LOCALE_USER_DEFAULT,
DISPATCH_METHOD, &params, &varResult, NULL, NULL);
            }
        }
        return hr;
    }
};
