使用 C# 更新 WISP(Windows Ink Service Platform)的注册表更改 [英] Update registry changes of WISP (Windows Ink Service Platform) with C#

问题描述

我正在尝试在 Windows 7 或 8 上为我的 WPF 绘图应用程序启用/禁用触摸功能.

I am trying to enable/disable touch capability on Windows 7 or 8 for my WPF drawing application.

据我搜索，链接 如何在应用程序、窗口或控制级别关闭所有触摸输入? 为触摸功能状态提供了注册表的正确位置.

As far as I searched, the link How to turn off all touch input at application, window or control level? gives a right location of the registry for touch capability status.

但是，它并没有即时受到影响，因为 Windows 系统可能无法确认更改.

However, it did not be affected on-the-fly because windows system may not be acknowledged the changes.

在我的假设中，需要使用 SystemParametersInfo 刷新 User32.dll 才能在不重新启动的情况下进行更改.但很难弄清楚如何做到这一点，因为我不知道哪个 SPI_something 与 WISP 相关.

In my assumption, User32.dll refresh with SystemParametersInfo is required to make changes without reboot. But hard to figure out how to do that because I don't know which SPI_something is related to WISP.

有没有其他方法或者你能帮我实现它吗?

Is there another method or could you help me to make it happen?

示例代码如下(与上面的 StackOverflow 引用链接非常相​​似)

The sample code is as below (pretty similar to above StackOverflow referenced link)

            RegistryKey regKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Wisp\Touch", true);
        if (regKey != null)
        {
            regKey.SetValue("TouchGate", 0x00000000); // Turn off touch.
            regKey.Close();

            // NOTIFY REGISTRY CHANGES TO WINDOWS
        }

推荐答案

问题的当前答案如何在应用程序、窗口或控件级别关闭所有触摸输入?使 Windows 重新读取注册表.请参阅:答案内部静态 void Notify_SettingChange() 方法.

The current answer to the question How to turn off all touch input at application, window or control level? also gives a way to make Windows to re-read registry. See: the answer's internal static void Notify_SettingChange() method.

SystemParametersInfo 中没有记录用于禁用触摸的 SPI_* 常量.此外，所有 SPI_ 常量都与辅助功能相关 - 而不是像触摸这样的通用功能.

There is no documented SPI_* constant for touch disabling in SystemParametersInfo. Moreover all the SPI_ constants there are related to accessibility features - not general features like touch.
