从Windows中提取键盘布局

Question

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:)

using System;
using System.Collections;
using System.IO;
using System.Reflection;

class KeyboardExtractor {

    static Object InvokeNonPublicStaticMethod(Type t, String name,
            Object[] args)
    {
        return t.GetMethod(name, BindingFlags.Static | BindingFlags.NonPublic)
            .Invoke(null, args);
    }

    static void InvokeNonPublicInstanceMethod(Object o, String name,
            Object[] args)
    {
        o.GetType().GetMethod(name, BindingFlags.Instance |
                BindingFlags.NonPublic) .Invoke(o, args);
    }

    static Object GetNonPublicProperty(Object o, String propertyName) {
        return o.GetType().GetField(propertyName,
                BindingFlags.Instance | BindingFlags.NonPublic)
            .GetValue(o);
    }

    static void SetNonPublicField(Object o, String propertyName, Object v) {
        o.GetType().GetField(propertyName,
                BindingFlags.Instance | BindingFlags.NonPublic)
            .SetValue(o, v);
    }

    [STAThread] public static void Main() {
        System.Console.WriteLine("Keyboard Extractor...");

        KeyboardExtractor ke = new KeyboardExtractor();
        ke.extractAll();

        System.Console.WriteLine("Done.");
    }

    Assembly msklcAssembly;
    Type utilitiesType;
    Type keyboardType;
    String baseDirectory;

    public KeyboardExtractor() {
        msklcAssembly = Assembly.LoadFile("C:\\Program Files\\Microsoft Keyboard Layout Creator 1.4\\MSKLC.exe");
        utilitiesType = msklcAssembly.GetType("Microsoft.Globalization.Tools.KeyboardLayoutCreator.Utilities");
        keyboardType = msklcAssembly.GetType("Microsoft.Globalization.Tools.KeyboardLayoutCreator.Keyboard");

        baseDirectory = Directory.GetCurrentDirectory();
    }

    public void extractAll() {

        DateTime startTime = DateTime.UtcNow;

        SortedList keyboards = (SortedList)InvokeNonPublicStaticMethod(
                utilitiesType, "KeyboardsOnMachine", new Object[] {false});

        DateTime loopStartTime = DateTime.UtcNow;

        int i = 0;
        foreach (DictionaryEntry e in keyboards) {
            i += 1;
            Object k = e.Value;

            String name = (String)GetNonPublicProperty(k, "m_stLayoutName");
            String layoutHexString = ((UInt32)GetNonPublicProperty(k, "m_hkl"))
                .ToString("X");

            TimeSpan elapsed = DateTime.UtcNow - loopStartTime;
            Double ticksRemaining = ((Double)elapsed.Ticks * keyboards.Count)
                        / i - elapsed.Ticks;
            TimeSpan remaining = new TimeSpan((Int64)ticksRemaining);
            String msgTimeRemaining = "";
            if (i > 1) {
                // Trim milliseconds
                remaining = new TimeSpan(remaining.Hours, remaining.Minutes,
                        remaining.Seconds);
                msgTimeRemaining = String.Format(", about {0} remaining",
                        remaining);
            }
            System.Console.WriteLine(
                    "Saving {0} {1}, keyboard {2} of {3}{4}",
                    layoutHexString, name, i, keyboards.Count,
                    msgTimeRemaining);

            SaveKeyboard(name, layoutHexString);

        }

        System.Console.WriteLine("{0} elapsed", DateTime.UtcNow - startTime);

    }

    private void SaveKeyboard(String name, String layoutHexString) {
        Object k = keyboardType.GetConstructors(
                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.
