如何以编程方式更改Windows的电源选项中的某些值？ [英] How change programmatically some values in power options of Windows?
问题描述
各位大家好！
我有一些目标，其中一些：
-enable / disable screensaver mode
-enable /禁用硬盘睡眠模式
-enable / disable关闭显示器
-enable / disable睡眠模式
我'googlin''将近3天！并找到了一小部分信息，这对我没有帮助。
我试图通过注册表更改此设置但是没有成功，因为我不是拥有管理员权限，我得到了ACCESS_DENIED。
我找到了电源管理API，但我不确定如何使用它。 MSDN没有充分的信息。
- 我已经使用SetThreadExecutionState和SystemParametersInfo来保护屏幕，但这些解决方案效果不好。首先我不能确定它是启用还是禁用，其次是bug。
- 我试图使用Registry，但我的应用程序没有管理员。许可，我为什么得到
ACCESS_DENIED
- 我找到了电源管理API。我不知道怎么用它。特别是PowerWritePossibleValue。
给我一些使用这个api的例子。
我正确的方法吗？怎样才能使用Power Management API任务？
如果你知道其他解决方案请写信给我
非常感谢
PS：我搜索了所有MSDN不是完整的信息和良好的链接
奖金问题：
我''我的应用程序可以更改操作系统的选项
本身（例如：在选项中，关闭显示10分钟，以编程方式我可以更改从不）？
Hello everybody!
I have some goals, some of those:
-enable/disable screensaver mode
-enable/disable sleep mode of HDD
-enable/disable turn off display
-enable/disable sleep mode
I''am googlin'' almost 3 days! and found a small part of info, that didn''t help me.
I tried to change this settings through Registry but it was unsuccessful because I don''t have administrator permission, I got ACCESS_DENIED.
I found Power management API, but I am not sure how use it. MSDN is not full of information.
--I have used SetThreadExecutionState and SystemParametersInfo for Screen saver, but those solutions works bad. First I can''t be sure is it enable or disabled, second with bug.
--I tried to use Registry, but my application without admin. permission, taht''s why I got
ACCESS_DENIED
--I found Power Management API. I don''t know how use it. Especially PowerWritePossibleValue.
Provide me some examples to use this api.
Am I on correct way?How can use Power Management API for my tasks?
Please write me if you know another solutions
Thanks a lot
P.S: I searched all MSDN is not full info and a lot of links in goodgle
Bonus question:
I''m a student and newer in programming is it good that my application can change options of OS
itself (for example: In options, turn off display for 10 minutes, programmatically I can change on Never)?
推荐答案
//我试图通过注册表更改此设置
//但它没有成功，因为我没有管理员权限，我得到ACCESS_DENIED。
作为一种可能的解决方案，
你可以编写一个由SYSTEM启动的服务
然后让你的应用与它沟通（为了写一些注册值）：）
// I tried to change this settings through Registry
// but it was unsuccessful because I don''t have administrator permission, I got ACCESS_DENIED.
As one possible solution,
you could write a service to be started by SYSTEM
and then let your application communicate with it (order to write some reg-values) :)
