WW_MOUSE_LL挂钩不被调用

我目前正在为我的应用程序创建一个AFKChecker。问题是，低级别的鼠标钩不会被调用。我检查过它是否返回0。所以键盘钩子工作，但不是鼠标钩子。我已经使用Google，但我仍然没有找到解决我的问题的方法。WW_MOUSE_LL挂钩不被调用

using System; 
using System.Diagnostics; 
using System.Runtime.InteropServices; 

namespace AFKChecker 
{ 
    public static class ActivityChecker 
    { 
     public static Int64 LastKeypress = 0; 
     public static int AFKTime = 300; 

     private const int WH_KEYBOARD_LL = 13; 
     public const int WH_MOUSE_LL = 14; 
     private static HookProc _keyproc = HookCallback; 
     private static IntPtr _keyhookID = IntPtr.Zero; 
     private static HookProc _mouseproc = HookCallback; 
     private static IntPtr _mousehookID = IntPtr.Zero; 

     public static void AddHook() 
     { 
      LastKeypress = Tools.UnixTime(); 
      _keyhookID = SetKeyboardHook(_keyproc); 
      _mousehookID = SetKeyboardHook(_mouseproc); 
     } 

     private static IntPtr HookCallback(
     int nCode, IntPtr wParam, IntPtr lParam) 
     { 
      LastKeypress = Tools.UnixTime(); 
      return CallNextHookEx(_keyhookID, nCode, wParam, lParam); 
     } 

     public static void RemoveHook() 
     { 
      UnhookWindowsHookEx(_keyhookID); 
      UnhookWindowsHookEx(_mousehookID); 
     } 

     public static Boolean IsAFK() 
     { 
      return (LastKeypress + AFKTime > Tools.UnixTime()); 
     } 

     private static IntPtr SetKeyboardHook(HookProc proc) 
     { 
      using (Process curProcess = Process.GetCurrentProcess()) 
      using (ProcessModule curModule = curProcess.MainModule) 
      { 
       return SetWindowsHookEx(WH_KEYBOARD_LL, proc, 
        GetModuleHandle(curModule.ModuleName), 0); 
      } 
     } 

     private static IntPtr SetMouseHook(HookProc proc) 
     { 
      using (Process curProcess = Process.GetCurrentProcess()) 
      using (ProcessModule curModule = curProcess.MainModule) 
      { 
       return SetWindowsHookEx(WH_MOUSE_LL, proc, 
        GetModuleHandle(curModule.ModuleName), 0); 
      } 
     } 

     private delegate IntPtr HookProc(
      int nCode, IntPtr wParam, IntPtr lParam); 

     [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)] 
     private static extern IntPtr SetWindowsHookEx(int idHook, 
      HookProc 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); 
    } 
}

好像你不打电话SetMouseHook，重新检查你的AddHook()功能：

public static void AddHook() 
    { 
     LastKeypress = Tools.UnixTime(); 
     _keyhookID = SetKeyboardHook(_keyproc); 
     _mousehookID = SetKeyboardHook(_mouseproc); // SetMouseHook() here? 
    }

哦，我愚蠢。我忘了改变这一点 – BlackVoid

安装鼠标/键盘钩子只是为了找到的空闲时间用户觉得我在概念上是错误的。如果windows没有提供更好的API，这应该是最后的手段。

A quick search揭示了为此设计的GetLastInputInfo API。和一个codeproject文章描述如何在C＃中做到这一点：Getting the user idle time with C#
