下面的脚本实现了激活系统托盘区（system tray）Outlook程序的效果（Windows XP），第一行是不在托盘区出现一个autohotkey的图标，这样做的好处是显得比较酷，缺点是如果想中断这个脚本，就只能在任务管理器里关进程（Autohotkey.exe）了。第二行是运行脚本的快捷键（这里是Win键+“]”键），后面是脚本的具体内容，大体意思是首先用TrayIcons函数找到进程"OUTLOOK.EXE"的各种参数，然后用PostMessage方法向这个进程发指令，令其窗口显示出来，TrayIcons函数中涉及了很多Windows API，俺就不懂了，好用就行。

使用方法：首先要安装Autohotkey_L v1.0.92.02，将下面的代码保存为一个 UTF-8格式 编码的文本文件，扩展名为ahk，双击运行之。

PostMessage, TrayInfo1, TrayInfo2, 0x0203,, ahk_id %TrayInfo3% ; 这句话实现了激活托盘区程序
