AutomateShellWindow,jiangsheng 大侠，请教问题？

// create a new IE instance and show it
//CComQIPtr<IWebBrowser2> m_pWebBrowser2;
m_pWebBrowser2.CoCreateInstance(CLSID_InternetExplorer);
HRESULT hr;
hr = m_pWebBrowser2->put_StatusBar(VARIANT_TRUE);
hr = m_pWebBrowser2->put_ToolBar(VARIANT_TRUE);
hr = m_pWebBrowser2->put_MenuBar(VARIANT_TRUE);
hr = m_pWebBrowser2->put_Visible(VARIANT_TRUE);

if(!::PathIsURL(m_strFileToFind))
m_strFileToFind=_T("http://blog.joycode.com/jiangsheng");
COleVariant vaURL( ( LPCTSTR) m_strFileToFind);
m_pWebBrowser2->Navigate2(
&vaURL, COleVariant( (long) 0, VT_I4),
COleVariant((LPCTSTR)NULL, VT_BSTR),
COleSafeArray(),
COleVariant((LPCTSTR)NULL, VT_BSTR)
);
看了你的文章AutomateShellWindow后，照着你说的这种方法create a new IE instance and show it ，但是总是会使m_pWebBrowser2为0x00000000，出现错误，是什么原因阿？请大侠帮忙！
