以编程方式打开或关闭飞行模式 Windows [英] Programmatically turn airplane mode on or off Windows

问题描述

我正在编写一个应用程序，需要在 Windows 上打开或关闭飞行模式.我看过这个问题，但答案只能得到状态，或者说你不能为 Metro 应用做这样的事情.我不制作现代/地铁应用程序，所以我不需要担心应用程序沙盒.

I am writing an app where I need to turn airplane mode on or off on windows. I have seen this question, but the answers only get the status, or say you cannot do such a thing for Metro apps. I am not making a modern/metro app, so I don't need to worry about application sandboxing.

有没有打开/关闭飞行模式的api，我应该如何使用它?

Is there an api to turn Airplane mode on/off, and how should I use it?

在我的用例中，我知道我可以控制它，并且用户可以接受.

另外，我发现 这个 msdn 问题，摘录如下:

Also, I found this msdn question with the following excerpt:

Windows 8(build 8250)，我可以在 Metro Style Network Setting UI 中打开/关闭飞行模式.

Windows 8(build 8250), I can turn on / off airplane mode in Metro Style Network Setting UI.

如何以编程方式执行此操作?

How to do this programmatically?

1. Microsoft 为无线单选按钮定义了 HID 使用代码(用法:0xC6).

1. Microsoft defined HID Usage code for Wireless Radio Button (Usage: 0xC6).

问题:无线电按钮是否有一些虚拟键码?如果是这样，应用程序可以通过 Keybd_event 发送此键码.

Question: Is there some virtual key code for Wireless Radio Button? If so, Application can send this keycode by Keybd_event.

WLANAPI.dll 导出 API WlanStoreRadioStateOnEnteringAirPlaneMode ，但没​​有该 API 的任何文档.

WLANAPI.dll export the API WlanStoreRadioStateOnEnteringAirPlaneMode , but there are no any document for this API.

问题:您能提供详细信息吗?是用来控制飞行模式的，这个API怎么调用?

Question: Can you provide detail information? Is it used to control Air Plane Mode, How to call this API?

显然(给出答案的摘要)，可以使用 MobileBroadbandRadioState 枚举检查飞行模式的状态.

So apparently (to give a summery of the answer), one can check the state of Airplane mode using the MobileBroadbandRadioState enum.

HID 路由可能是一种可能性 文档.显然这是一个是否可以将代码0xc6发送到kbd_event的问题.

The HID route may be a possibility docs. Apparently it is a question of whether one can send the code 0xc6 to kbd_event.

显然有一个名为 Network Flyout 的窗口，我正在考虑枚举孩子以找到开关，但我没有取得太大的成功.我将不得不使用更多的 Spy++ 来找出答案.

Apparently there is a window called Network Flyout and I was thinking of enumerating the children to find the switch, but I haven't had much success. I'll have to use Spy++ some more to find out.

推荐答案

以下所有内容都是我通过逆向工程发现的.

All of the following I discovered myself via reverse engineering.

Windows 内部用于获取/设置飞行模式的内部 API 使用对RMsvc"的 COM 调用.服务(位于RMApi.dll"中).该服务正在导出一个工厂和接口，其中包含获取/设置飞行模式的功能:

The internal API used internally by windows to get/set Airplane mode makes use of COM calls to "RMsvc" service (which is located in "RMApi.dll"). That service is exporting a factory and interface which contains functions to get/set flight mode:

#include <Windows.h>
