使用 powershell 更改屏幕方向 - 注册表值存储在哪里? [英] Change screen Orientation with powershell - Where are the registry values stored?
问题描述
来自瑞典的 Hej，
我正在尝试参考帖子中的代码:Powershell 脚本更改屏幕方向
I am trying out the code from the reference post: Powershell script to change screen Orientation
脚本有效.目标是确保旋转是横向 - 默认或纵向 90 度顺时针.
The script works. The goal is to make sure that the rotation is either landscape - default or portrait 90 degrees clockwise.
我需要将当前代码更改为只允许 2 个值或确保脚本只运行一次.
I need to either change the current code to just allow 2 values or make sure that the script only runs once.
无论哪种方式，我都需要知道 CDS_UPDATEREGISTRY 的注册表项存储在哪里.虽然我无法弄清楚每次轮换的值更改在注册表中的哪个位置存储在注册表中?
Either way, I need to know where the registry keys are stored for the CDS_UPDATEREGISTRY. Although I cannot figure out where in the registry the value change for each rotation are stored in the registry?
有没有人知道值存储在哪里?
Does anyone by any chance know where the values are stores?

推荐答案
<#
0 = Default
1 = 90°Left (Counter-Clockwise)
2 = 180°
3 = 270° (90°Right Clockwise)
#>
通过在 ChangeResolution(0) 中添加值 0、1、2、3 作为参数，该函数将使脚本能够定义纵向或横向.
By adding the values 0, 1, 2, 3 as a parameter in ChangeResolution(0) the function will enable the script to define the portrait or landscape orientation.
