Re: PassthruAPP: QueryServiceFromClient(&spWindowForBinding); returns null for Media player request ?

Actually i found the way to communicate between CTestAPP and CTestSink,
again thanks to Igor.
My Continue method is like:

STDMETHODIMP CTestAPP::Continue(
/* [in] */ PROTOCOLDATA *pProtocolData)
{
ATLASSERT(m_spInternetProtocol != 0);

//MessageBox(NULL, "EE@", "", MB_OK);
CComPtr<IWindowForBindingUI> spWindowForBinding;
HRESULT hr =
m_internetSink.QueryServiceFromClient(&spWindowForBinding);
..............................

}

the problem now is that m_internetSink.QueryServiceFromClient fails,
does not even gets to return anything, throws atlassert error at:


if (SUCCEEDED(hr))
{
hr = spClientProvider->QueryService(guidService, riid, ppvObject);
}

any ideas why ?

I'm using your code exactly and i got to the problem that there are two
classes: CTestSink and CTestAPP, it seems like Continue is in CTestAPP,
but i cannot do QueryServiceFromClient because this is a CTestSink
method,
First: is CTestAPP's Continue i need to get the window in ?
And: is there a way to QueryServiceFromClient in CTestAPP, or
communicate somehow between them, since the headers i need are
accesible in CTestSink::OnProgress while the window i also need is
accesible in CTestAPP...

Thanks.

I'm using Igor's toolkip, and as i need to know which IE window does
each request i have:

PROTOCOLDATA protdata;
protdata.grfFlags = PD_FORCE_SWITCH;
Switch(&protdata);

CComPtr<IWindowForBindingUI> spWindowForBinding;
QueryServiceFromClient(&spWindowForBinding);

Just calling Switch doesn't magically make subsequent
QueryServiceFromClient work. When you call Switch, soon your client will
turn around and call Continue on you, on the main thread. That's the
point of the exercise. You should call QueryServiceFromClient from your
Continue implementation.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
