从Windows中提取键盘布局

好的,这是一个有点奇怪的问题.

我们有一个触摸屏应用程序(即没有键盘).当用户需要输入文本时,应用程序会显示虚拟键盘 - 手工构建在WinForms中.

为每种新语言手工制作这些东西都是猴子的工作.我认为Windows必须将此键盘布局信息隐藏在某些dll中的某处.无论如何都会从窗口获取此信息？

欢迎其他想法(我认为至少从xml文件生成的东西必须比在VS中手动执行更好).

(注意:说了所有这些,我注意到有一个日文键盘,状态机和所有...,所以XML可能不够)

更新:关于这个主题的相当不错的系列(我相信)在这里

Microsoft Keyboard Layout Creator可以加载系统键盘并将其导出为.klc文件.由于它是用.NET编写的,因此您可以使用Reflector查看它是如何做到的,并使用反射来驱动它.这是使用以下C#代码创建的Windows 8中187个键盘的.klc文件的zip文件.请注意,我最初是为Windows XP编写的,现在使用Windows 8和屏幕键盘,它真的很慢,似乎崩溃任务栏:/但是,它确实有效:)

class KeyboardExtractor {

        SortedList keyboards = (SortedList)InvokeNonPublicStaticMethod(

        DateTime loopStartTime = DateTime.UtcNow;

        int i = 0;
        foreach (DictionaryEntry e in keyboards) {

                // Trim milliseconds
                remaining = new TimeSpan(remaining.Hours, remaining.Minutes,
                        remaining.Seconds);

                    msgTimeRemaining);

    }

    private void SaveKeyboard(String name, String layoutHexString) {

                BindingFlags.Instance | BindingFlags.NonPublic)[0]
            .Invoke(new Object[] {
                        new String[] {"", layoutHexString},
                    false});

        SetNonPublicField(k, "m_fSeenOrHeardAboutPropertiesDialog", true);
        SetNonPublicField(k, "m_stKeyboardTextFileName",
                String.Format("{0}\\{1} {2}.klc",
                    baseDirectory, layoutHexString, name));
        InvokeNonPublicInstanceMethod(k, "mnuFileSave_Click",
                new Object[] {new Object(), new EventArgs()});

        ((IDisposable)k).Dispose();
    }

}

基本上,它获取系统上所有键盘的列表,然后为每个键盘加载它在MSKLC中,设置"另存为"文件名,说明它是否已经配置了自定义键盘属性,然后模拟点击文件 - >保存菜单项.
