window 系统托盘不自动隐藏

https://hianz.wordpress.com/2013/09/03/new-windows-tray-notification-manager-is-here/

1.PowerShell脚本实现原文链接

例子：将下面代码复制到一个脚本中去例如123.ps1,

执行时输入  ./123.ps1 myapp.exe < 显示参数>（0=不活动时隐藏 1=总是隐藏 2=总是显示）

执行完成后需要自己重启Explorer.exe，才能得到效果。

通过这种方法会存在一种问题是需要重启Explorer.exe，所以界面会闪烁一下。

这种方法和上面的powershell一样，会导致界面闪烁。

3.利用windowAPI实现

windows是有api去控制托盘显示和隐藏的，只不过它未开放给我们，但是有人找到怎么调用它的方法了。原文链接

具体在win7上工作的很好，win8没测试，但是win10 1809没有反应。
