我编写了一个脚本，将主屏幕方向更改为纵向。我的屏幕是1920X1200 它运行并且没有报告错误。但屏幕没有像我预期的那样旋转。
代码是从Set-ScreenResolution（Andy Schneider）修改的 有人可以帮我看看吗？
一些参考网站：
Set-ScreenResolution： http://gallery.technet.microsoft.com/ScriptCenter/2a631d72-206d-4036-a3f2-2e150f297515/
更改oridentation的C代码（MSDN）以编程方式更改屏幕方向： http://msdn.microsoft.com/en-us/library/ms812499.aspx
