大家好，我在用代码下载网页时，发现下载后有点问题，前部份的内容是正确的，到文件末尾就有点错误了

这造成我调用IHTMLAnchorElement::get_href
这个函数时，取到链接是错误的；
取得链接如：about:blank/News/List.asp?CategoryID=14
正确的链接应该是： http:\\www.xxx.com/News/List.asp?CategoryID=14

请大家帮帮忙，谢谢！

下载代码：

C/C++ code


bool CHtmlContent::GetSourceHtml( const CString &theUrl, CStringBuf &buf ) 
{
    CInternetFile* file = NULL;
    CInternetSession session;
    CString str;
    try
    {
        file = (CInternetFile*) session.OpenURL(theUrl); 
    }
    catch (CInternetException* m_pException)
    {
        file = NULL; 
        m_pException->Delete();
        return false;
    }
    buf.m_buf="";
    while( file->ReadString(str) != NULL )
    {
        buf.m_buf+=str+_T("\n");
    }
    PrintBuf(buf.m_buf);
    return true;
}

//正确的

我搞不明白为什么根目录是about:blank

我是能过上面的代码把html文件给下载下来，然后再把这些内容通过下面的代码写到文档里面, 再由文档取得IHTMLAnchorElement，再通过IHTMLAnchorElement::get_href取得连接，结果发现连接的根目录不对

我查一下下载下来的内容与通过"ie的查看菜单==>源文件菜单"取下的内容对比一下,结果发现内容有点出入
具体不同点在上面

//将buf写入document

C/C++ code


IHTMLDocument2Ptr  CHtmlContent::GetDocument( CStringBuf &buf )
{
    IHTMLDocument2Ptr pDoc2;

    HRESULT hr = CoCreateInstance(CLSID_HTMLDocument, NULL, CLSCTX_INPROC_SERVER, 
            IID_IHTMLDocument2, (void**)&pDoc2);
    if( SUCCEEDED(hr) )
    {
        //put the code into SAFEARRAY and write it into document
        SAFEARRAY* psa = SafeArrayCreateVector(VT_VARIANT, 0, 1);
        VARIANT *param;
        
        _bstr_t bsData = (LPCTSTR)buf.m_buf;
        hr = SafeArrayAccessData(psa, (LPVOID*)&param);
        param->vt = VT_BSTR;
        param->bstrVal = (BSTR)bsData;
        
        hr = pDoc2->write(psa);
        hr = pDoc2->close();
        
        SafeArrayDestroy(psa);
    }
    return pDoc2;
}
