刚好碰到一个朋友要求，要隐藏窗体界面，网上下载了几个，都不太合意，很多都被杀毒软件认为是有害软件，没办法，只能自已写个隐藏窗体界面的小工具。
.NET 2.0, C#
/***************************************************
* 开发者:0x001 *
* 开发时间：2012-05-17 *
* 功能：List 获取所有显示的窗口列表名称 *
* Keyword 是要隐藏的窗口名称包含的关键字 *
* Start时正式关闭,Stop时关闭按钮将隐藏程序 *
* 本程序隐藏时 Ctrl+Alt+9 激活主界面 *
* Start之后生隔5秒扫描一次窗口，继续隐藏 *
