为什么我用下列代码无法在CHtmlView里显示Search工具栏呢？如何改才能达到目的？

IWebBrowser2 *pBrowser = NULL; // Ensure that our site is an browser window HRESULT hr = m_pBrowserApp->QueryInterface(IID_IWebBrowser2, (void **) &pBrowser); if (SUCCEEDED(hr)) {     // Display the band object (the Search bar in this case)     VARIANT vtBandGUID, vtShow;     vtBandGUID.vt = VT_BSTR;     //把这里的CLSID换成你的工具条CLSID     vtBandGUID.bstrVal = SysAllocString(OLESTR("{30D02401-6A81-11d0-8274-00C04FD5AE38}"));     vtShow.vt = VT_BOOL;     vtShow.boolVal = TRUE;     pBrowser->ShowBrowserBar(&vtBandGUID, &vtShow, 0);     SysFreeString(vtBandGUID.bstrVal);     pBrowser->Release(); }
