C＃鼠標鉤入特定進程

我正在運行一個應用程序，我希望在按住鼠標左鍵的同時重複單擊左鍵單擊鼠標（因此基本上不需要繼續單擊）。我編寫了一個小型測試應用程序，它鉤住鼠標事件，並聽取lb向下/向上事件。不過，該應用程序會在桌面上的任何位置監聽鼠標點擊。有沒有辦法讓它只聽一個特定的過程？C＃鼠標鉤入特定進程

下面是測試程序我使用監聽鼠標點擊：

class Program 
{ 
     private delegate IntPtr LowLevelMouseProc(int nCode, IntPtr wParam, IntPtr lParam); 
     private static LowLevelMouseProc _proc = HookCallback; 
     private static IntPtr _hookID = IntPtr.Zero; 
     private static bool _leftButtonDown; 

     public static void Main() 
     { 
      _hookID = SetHook(_proc); 
      Application.Run(); 
      UnhookWindowsHookEx(_hookID); 
     } 

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

     private static IntPtr HookCallback(
      int nCode, IntPtr wParam, IntPtr lParam) 
     { 
      if (nCode >= 0 && 
       MouseMessages.WM_LBUTTONUP == (MouseMessages)wParam) 
      { 
       _leftButtonDown = false; 
       Console.WriteLine(_leftButtonDown); 
      } 

      if (nCode >= 0 && 
       MouseMessages.WM_LBUTTONDOWN == (MouseMessages)wParam) 
      { 
       _leftButtonDown = true; 
       Console.WriteLine(_leftButtonDown); 
       StartTest(); 
      } 
      return CallNextHookEx(_hookID, nCode, wParam, lParam); 
     } 

     private static void StartTest() 
     { 
      Task.Factory.StartNew(() => 
       { 
        while (_leftButtonDown) 
        { 
         Console.WriteLine("SENDING"); 
        } 
       }); 
     } 

     private const int WH_MOUSE_LL = 14; 

     private enum MouseMessages 
     { 
      WM_LBUTTONDOWN = 0x0201, 
      WM_LBUTTONUP = 0x0202

改爲指定SetWindowsHookEx（）的線程ID參數。 –

感謝漢斯。如果您將答案添加爲回覆，我可以將您的答案標記爲已接受。 – Flack

正如評論指出的那樣，你可以使用SetWindowsHookEx函數的）的第四個參數（中，dwThreadId說法，是有選擇性的。您需要傳遞要監視的進程的GUI線程的線程ID。如果你有一個進程擁有的窗口的句柄，用GetWindowThreadProcessId（）來獲得值。如果它是你自己的進程，那麼使用GetCurrentThreadId（）。如果它是Winforms應用程序，則支持IMessageFilter而不是掛鉤。
