I've looked into it, you need to run the hook on its own context via "Application.Run();" to get it working:
using System; using System.Diagnostics; using System.Runtime.InteropServices; using System.Threading.Tasks; using System.Windows.Forms; using robotManager.Helpful; using wManager.Plugin; public class Main : IPlugin { public void Initialize() { KeyBoardHook.Initialize(); KeyBoardHook.OnKeyDown += KeyDown; } public void Dispose() { KeyBoardHook.OnKeyDown -= KeyDown; KeyBoardHook.Dispose(); } public void Settings() { } private static void KeyDown(object sender, KeyBoardHook.KeyArgs keyArgs) { Logging.Write(keyArgs.Key.ToString()); } public class KeyBoardHook { private const int WH_KEYBOARD_LL = 13; private const int WM_KEYDOWN = 0x0100; private const int WM_KEYUP = 0x101; private static readonly LowLevelKeyboardProc Proc = HookCallback; private static IntPtr _hookId = IntPtr.Zero; private static Keys _lastKeyDown = Keys.None; public delegate void KeyBoardHookEventHandler(object sender, KeyArgs e); public static event KeyBoardHookEventHandler OnKeyDown = delegate{}; public static event KeyBoardHookEventHandler OnKeyUp = delegate{}; internal static void Initialize() { Task.Factory.StartNew(() =>//avoid thread blocking from Application.Run(); { _hookId = SetHook(Proc); Application.Run(); //important! need to run in its own "context" }); } internal static void Dispose() { UnhookWindowsHookEx(_hookId); Application.Exit(); } private static IntPtr SetHook(LowLevelKeyboardProc proc) { using (var curProcess = Process.GetCurrentProcess()) using (var curModule = curProcess.MainModule) { return SetWindowsHookEx(WH_KEYBOARD_LL, proc, GetModuleHandle(curModule.ModuleName), 0); } } private delegate IntPtr LowLevelKeyboardProc(int nCode, IntPtr wParam, IntPtr lParam); private static IntPtr HookCallback(int nCode, IntPtr wParam, IntPtr lParam) { if (nCode < 0) return CallNextHookEx(_hookId, nCode, wParam, lParam); if (wParam == (IntPtr) WM_KEYDOWN) { var vkCode = (Keys) Marshal.ReadInt32(lParam); if (_lastKeyDown == vkCode) return CallNextHookEx(_hookId, nCode, wParam, lParam); OnKeyDown(null, new KeyArgs(vkCode)); _lastKeyDown = vkCode; } else if (wParam == (IntPtr) WM_KEYUP) { var vkCode = (Keys) Marshal.ReadInt32(lParam); OnKeyUp(null, new KeyArgs(vkCode)); if (_lastKeyDown == vkCode) _lastKeyDown = Keys.None; } return CallNextHookEx(_hookId, nCode, wParam, lParam); } [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr SetWindowsHookEx(int idHook, LowLevelKeyboardProc lpfn, IntPtr hMod, uint dwThreadId); [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)] [return: MarshalAs(UnmanagedType.Bool)] private static extern bool UnhookWindowsHookEx(IntPtr hhk); [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode, IntPtr wParam, IntPtr lParam); [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr GetModuleHandle(string lpModuleName); public class KeyArgs : EventArgs { public Keys Key { get; private set; } public KeyArgs(Keys key) { this.Key = key; } } } } So far it worked well.
