Re: How to return parameters in an ATL COM component event function?
I was able to get it working with the CComVariant like this:
HRESULT Fire_Continue(VARIANT_BOOL * pContinue, long * pNumb)
{
T* pT = static_cast<T*>(this);
int nConnectionIndex;
int nConnections = m_vec.GetSize();
CComVariant varResult;
CComVariant* pvars = new CComVariant[2];
VARIANT_BOOL vntbContinue = *pContinue; // you can pass in a
parameter in case it needs to be processed here
long lNumb = *pNumb;
for (nConnectionIndex = 0; nConnectionIndex < nConnections;
nConnectionIndex++)
{
pT->Lock();
CComPtr<IUnknown> sp = m_vec.GetAt(nConnectionIndex);
pT->Unlock();
IDispatch* pDispatch = reinterpret_cast<IDispatch*>(sp.p);
if (pDispatch != NULL)
{
VariantClear(&varResult);
V_VT(&pvars[1]) = VT_BYREF | VT_BOOL;
V_BOOLREF(&pvars[1]) = &vntbContinue;
V_VT(&pvars[0]) = VT_BYREF | VT_I4;
V_I4REF(&pvars[0]) = &lNumb;
DISPPARAMS disp = { pvars, NULL, 2, 0 };
pDispatch->Invoke(0x1, IID_NULL, LOCALE_USER_DEFAULT,
DISPATCH_METHOD, &disp, &varResult, NULL, NULL);
}
}
*pContinue = vntbContinue;
*pNumb = lNumb;
::VariantClear(&varResult);
return varResult.scode;
}
Thank you!
