使用AAUTO语言开发的云桌面登录客户端

AAUTO是一个国产小众语言，和lua算是近亲，官方网站 www.aau.cn。

使用aauto的优点我认为对于我来说最主要的有以下两点：

1.无需臃肿的框架类似.NET FRAMEWORK、Adobe AIR等便可开发出小巧而实用的windows程序

2.支持HTMLLAYOUT，对于原来熟悉html+css的web开发者来说是个福音，降低了学习成本

废话不多说了，下面开始介绍下我使用aauto这个短小精悍的语言所开发的访问使用CloudStack所创建的虚拟机的云桌面访问客户端。

界面演示

实现功能

该客户端在输入用户名密码验证登录成功后

1.屏蔽了windows，ALT+F4 以禁止用户返回原生桌面或关闭当前程序（其实屏蔽ALT+F4）

架构详解

下图是该项目的全部文件目录树。

该客户端仅有一个主窗体文件main.aau,界面演示图中的效果是有layout中的index.html实现。sys.ini中配置保存的用户名及登录验证服务网址.
