1.VS2005 + IE8无法调试

因为IE8是多线程的。按照tab调试（原因百度）

打开: HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main

添加一个新DWORD键值TabProcGrowth，并且把值设为0.

URL劫持，重定向

void STDMETHODCALLTYPE CSevenFanliBHO::OnBeforeNavigate2(IDispatch* pDisp, VARIANT* URL, VARIANT* pvtFlags, VARIANT* pvtTargetFrameName, 
  VARIANT* pvtPostData, VARIANT* pvtHeaders, VARIANT_BOOL* pvbCancel)
{
  if (0 == ::wcscmp(URL->bstrVal, L"https://www.baidu.com/"))
  {
    //*pvbCancel = VARIANT_TRUE;
    VARIANT varNewUrl;
    varNewUrl.vt = VT_BSTR;
    varNewUrl.bstrVal = ::SysAllocString(L"https://www.hao123.com/");
    IWebBrowser2* pWB2;
    pDisp->QueryInterface(IID_IWebBrowser2, (void**)&pWB2);
    pWB2->Stop();//此句可有可无 
    pWB2->Navigate2(&varNewUrl, pvtFlags, pvtTargetFrameName, pvtPostData, pvtHeaders);    
    ::SysFreeString(varNewUrl.bstrVal);
  }   
}
