// Query pUnkSite for the IWebBrowser2 interface.
m_spWebBrowser2 = (IWebBrowser2 *)pUnkSite;
//m_spWebBrowser2->AddRef();
HRESULT hr = CoMarshalInterThreadInterfaceInStream (IID_IWebBrowser2,
m_spWebBrowser2, &pStream);


and in worker thread :
HRESULT hr = CoInitialize(NULL);
hr = CoGetInterfaceAndReleaseStream(pStream,IID_IWebBrowser2,(VOID
**)&m_spWebBrowser2);
GetText();
where GetText parse frames of the documents.

You appear to be using the same member variable, m_spWebBrowser2, in
both places. Of course the two pointers appear the same - you are
overwriting one with the other. Give the worker thread its own variable
in which to keep the pointer.

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
