How to get keyboard language in XNA?

Introduction

Hello friends, wknowing how to get keyboard language may be very boring for thos who want a fast answer. Well there are lots of ways to do it, but the fastest and more reliable code is to use Windows APIs.

So let's go get it.

Using the code

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Globalization;
using System.Windows.Forms;
namespace Language_Learning_Application
{
    public class CurrentCultureInfo
    {
        //
        [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
        private static extern IntPtr GetForegroundWindow();
        [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
        private static extern int GetWindowThreadProcessId(IntPtr handleWindow, out int lpdwProcessID);
        [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
        private static extern IntPtr GetKeyboardLayout(int WindowsThreadProcessID);
        //
        public CurrentCultureInfo()
        {
            IntPtr hWnd = GetForegroundWindow();
            int WinThreadProcId = GetWindowThreadProcessId(hWnd, out lpdwProcessId);
            IntPtr KeybLayout = GetKeyboardLayout(WinThreadProcId);
            for (int i = 0; i < installedInputLanguages.Count; i++)
            {
                if (KeybLayout == installedInputLanguages[i].Handle) 
                   currentInputLanguage = installedInputLanguages[i].Culture;
            }
        }
        //
        #region Fields & Properties
        private  int lpdwProcessId;
        private  InputLanguageCollection installedInputLanguages = InputLanguage.InstalledInputLanguages;
        private  CultureInfo currentInputLanguage;
        public string InputLangTwoLetterISOLanguageName
        {
            get { return currentInputLanguage.TwoLetterISOLanguageName; }
        }
        public  string InputLangThreeLetterWindowsLanguageName
        {
            get { return currentInputLanguage.ThreeLetterWindowsLanguageName; }
        }
        public  string InputLangThreeLetterISOLanguageName
        {
            get { return currentInputLanguage.ThreeLetterISOLanguageName; }
        }
        public  string InputLangNativeName
        {
            get { return currentInputLanguage.NativeName; }
        }
        public  string InputLangName
        {
            get { return currentInputLanguage.Name; }
        }
        public  int InputLangLCID
        {
            get { return currentInputLanguage.LCID; }
        }
        public  int InputLangKeyboardLayoutId
        {
            get { return currentInputLanguage.KeyboardLayoutId; }
        }
        public  string InputLangEnglishName
        {
            get { return currentInputLanguage.EnglishName; } 
        }
        public  string InputLangDisplayName
        {
          get {   return currentInputLanguage.DisplayName; }
        }
        #endregion
    }
}

We used Windows DLLs to reach our keyboard layout. Be sure to add the references you need above. Now wherever you need to know the keyboard language, put the code below:

 CurrentCultureInfo myclsCurrentCultureInfo = new CurrentCultureInfo();
string strCulture = myclsCurrentCultureInfo.InputLangName;

So here we create an object from our class that initialized our current input language.

public CurrentCultureInfo()
{
    IntPtr hWnd = GetForegroundWindow();
    int WinThreadProcId = GetWindowThreadProcessId(hWnd, out lpdwProcessId);
    IntPtr KeybLayout = GetKeyboardLayout(WinThreadProcId);
    for (int i = 0; i < installedInputLanguages.Count; i++)
    {
        if (KeybLayout == installedInputLanguages[i].Handle) currentInputLanguage = installedInputLanguages[i].Culture;
    }
} 

Well, it was easy, Thank you for your attention.

To create a multilanguage application you need to know the Windows current language, here was a very easy and not boring way we did it.
