C/C++编程操作IIS7
由于IIS6与IIS7以后的编程接口更改，导致IIS6的项目无法访问IIS7，研究了几天时间，终于有些眉目，现在记录如下。首先需要说明如下问题：
1.iis7以后的版本不再支持nntp （http://forums.iis.net/t/1160175.aspx这个页面有明显说明）
2.如果要使用smtp需要系统安装iis6兼容组件
3.如果要使用iis6的接口来访问iis7的信息需要安装iis6兼容组件
网络上很多关于IIS6的编程接口应用，现只说明C/C++编程操作IIS7的方法。详细的操作方式及说明，可以查看微软的在线MSDN（msdn.microsoft.com）
