修改部分内容，原始文件见下面的声明，所有权属于原著者，这里只是对此修改了一部分内容。
本次修改内容如下：
添加了对托管C++关键字的支持；
修改默认显示字体为Fixedsys；
修改默认颜色模板为Virtual Studio2008中的加亮颜色（稍微有点不同）。
这里有个转换后的效果，可以看下
http://hi.baidu.com/flyskymlf/blog/item/6ceefb178b23b20ac93d6dee.html
使用方法：把下面的内容复制保存为.html格式后，在浏览器打开即可，具体怎么操作不多说了，打开之后就知道了，傻子都会^_^
注：注意转换之后，要是想保存在html文件中的，直接复制转换后的那一堆“乱码”（网页源代码）即可，要是想复制到Blog文章里时，注意要先点击“在新窗口查看效果”，然后复制打开的新窗口里面的'所见即所得代码'。

<!--
说明：下面的代码是根据 http://www.bedaux.net/cpp2html/ 上的代码修改而成。
因为原代码功能强大，支持xhtml和old html两种标签，且生成的代码中带有html页面头很多meta信息，
所以，不适合作为生成blog的代码使用。 我对原代码进行了修改，生成的代码极为简练，可以直接粘贴入blog的编辑框中使用(vckbase,csdn,
博客园等均适用)。所以，大家完整的代码请到bedaux.net查找，感谢bedaux.net给我们提供了
这个好东东。
