Hi,

I am new to com devolpment.

How can i query class info or guid of clients who are connected (by
connection point) to the ie instance from another com exe.

Here is the code which i was using
but querying IProvideClassInfo fails

        SHDocVw::IShellWindowsPtr m_spSHWinds;
        m_spSHWinds.CreateInstance(__uuidof(SHDocVw::ShellWindows));
        long nCount = m_spSHWinds->GetCount();
        IDispatchPtr spDisp;
          _variant_t va(1, VT_I4);
          spDisp = m_spSHWinds->Item(va);

          SHDocVw::IWebBrowser2Ptr spBrowser(spDisp);

          // Retrieve and store the IWebBrowser2 pointer
          CComQIPtr<IWebBrowser2, &IID_IWebBrowser2> m_pWebBrowser2;
          m_pWebBrowser2 = spBrowser;
          if (m_pWebBrowser2 != NULL)
          {
                  // Retrieve and store the IConnectionPointerContainer
pointer
                  m_pICPC = m_pWebBrowser2;
                  if (m_pICPC != NULL)
                  {

                                       HRESULT hr = S_FALSE;
                                      CComPtr<IConnectionPoint>m_pICP;
                                       DWORD m_dwCookie;
                                        // Receives the connection
point for WebBrowser events
                            hr =
m_pICPC->FindConnectionPoint(DIID_DWebBrowserEvents2, &m_pICP);
                                        if (FAILED(hr)) return
E_POINTER;
                                   IEnumConnections* m_pEnumConnections

= NULL;
                                   hr =
m_pICP->EnumConnections(&m_pEnumConnections);
                                   if (FAILED(hr)) return E_POINTER;

                                  m_pEnumConnections->AddRef();
                                  CONNECTDATA cd;
                                   unsigned long pcFetched = 0;
                                  while (m_pEnumConnections->Next(1,
&cd, &pcFetched)== S_OK)
                                 {

CComPtr<IProvideClassInfo2>m_pIProvideClassInfo2;
           hr = cd.pUnk->QueryInterface(IID_IProvideClassInfo2,
(void**)&m_pIProvideClassInfo2);

//FAILS WHEN CALLING QUERY INTERFACE

                        cd.pUnk->Release();
                           }
                               m_pEnumConnections->Release();

                                   }
                 }

Thanks in advance,
