How to get keyboard layout name

Question

A piece of code:

[DllImport("user32.dll", SetLastError = true)] public static extern ushort GetKeyboardLayout([In] int idThread); [DllImport("user32.dll", SetLastError = true)] public static extern int GetWindowThreadProcessId([In] IntPtr hWnd,[Out, Optional] IntPtr lpdwProcessId); [DllImport("user32.dll", SetLastError = true)] public static extern IntPtr GetForegroundWindow(); public static string mss; static ushort GetKeyboardLayout() { return GetKeyboardLayout(GetWindowThreadProcessId(GetForegroundWindow(), IntPtr.Zero)); }

Now when i try to get keyboard layout

 ushort lang = GetKeyboardLayout(); mss = lang.ToString(); TextBox1.Text = "Первоначальная раскладка: " + mss + "\n";

It does not show Rus or Eng but in figures such as 1049 etc.

How to fix it?

 using System.Globalization;

 int id = GetKeyboardLayout(); CultureInfo ci = CultureInfo.GetCultureInfo(id); this.Text = id + " " + ci.ThreeLetterISOLanguageName + " " + ci.Name;

And there is still a lot of interesting things.

Please note that you have the wrong P / Invoke signature! The GetKeyboardLayout function returns a handle, so the correct signature is:

 [DllImport("user32.dll")] static extern IntPtr GetKeyboardLayout(int idThread);

According to the documentation

There is no trace of the keyboard.

Therefore, we need to extract the lower word:

 static ushort GetKeyboardLayout() { return (ushort)GetKeyboardLayout(GetWindowThreadProcessId(GetForegroundWindow(), IntPtr.Zero)); }

+1, but the P / Invoke-signature for the GetKeyboardLayout of the vehicle is incorrect => it is worth waiting for the crash.
And I get GetCultureInfo, if you do not trim the argument high bits ( id & 0xffff ).
But after all there is nothing to fall - it's just a register.
