用HttpQueryInfo一定能读取到HTTP状态字吗？解决方法

用HttpQueryInfo一定能读取到HTTP状态字吗？
假设网络没有问题，客户端把请求提交到服务器后，服务器返回Http状态，用HttpQueryInfo一定能读取到HTTP状态字吗？应该怎么读取呢？

------解决方案--------------------
DWORD dwStatusCode;
DWORD dwSize = sizeof(DWORD);
BOOL bRet = HttpQueryInfo(hFile, HTTP_QUERY_STATUS_CODE|HTTP_QUERY_FLAG_NUMBER, &dwStatusCode, &dwSize, NULL);
------解决方案--------------------
如果网络没出错的话..是可以的.

Example Code
This example demonstrates a call to HttpQueryInfo.

bRet = HttpQueryInfo(hResource, HTTP_QUERY_RAW_HEADERS_CRLF,
lpvSomeBuffer, &dwSize, NULL);
