关于豆丁文库效果的实现(类似百度文库)，注册WINDOWS服务，以拒绝分配给IIS过高的权限

最近应用FLASHPAPER2.2来实现百度文库（豆丁文库）的功能，但是要服务器配置的时候IIS需要配置到管理员的权限才能实现打印。

CSDN讨论地址：http://topic.csdn.net/u/20120717/07/55bb1837-07a7-465b-bc88-895a7c45882a.html

在WEB上给网站如此高的运行权限会有相当大的完全隐患，特别是文档功能需要开放上传功能，安全隐患就更高了。

因此我将文档转换的操作从WEB中分享出来，写成服务注册到服务器上，在服务器上定时进行文档转换。

创建一个新的控制台应用程序，将最下的代码贴入（各有所好，请自我调整）。

并在VS的控制台使用命令

installutil xxx.exe(你的应用程序生成的文件)

来注册服务，卸载服务的命令是 installutil /u xxx.exe(你的应用程序生成的文件)
