Question

求详细的写事件方法和HOOK API的方法 ！！！！C#语言

现在在做一个注册表监控的程序，里面用到一个时间的句柄。而那个事件需要自己定义，目前完全不接触过事件定义！目的在于，当注册表发生改变时，用那个事件去拦截，用户同意后在继续。如果不同意则取消！
知道里面要用到API所以请求详细的帮助，谢谢
写错了 里面用到一个事件的句柄！！不好意思

Answer 1

全局HOOK API （C#) 的实现
主要实现代码
代码:
[DllImport("user32.dll", CharSet = CharSet.Auto,
CallingConvention = CallingConvention.StdCall, SetLastError = true)]
private static extern int SetWindowsHookEx(
int idHook,
HookProc lpfn,
IntPtr hMod,
int dwThreadId);

[DllImport("user32.dll", CharSet = CharSet.Auto,
CallingConvention = CallingConvention.StdCall, SetLastError = true)]
private static extern int UnhookWindowsHookEx(int idHook);

[DllImport("user32.dll", CharSet = CharSet.Auto,
CallingConvention = CallingConvention.StdCall)]
private static extern int CallNextHookEx(
int idHook,
int nCode,
int wParam,
IntPtr lParam);

[DllImport("user32")]
private static extern int ToAscii(
int uVirtKey,
int uScanCode,
byte[] lpbKeyState,
byte[] lpwTransKey,
int fuState);

[DllImport("user32")]
private static extern int GetKeyboardState(byte[] pbKeyState);

[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
private static extern short GetKeyState(int vKey);
使用SetWindowsHookEx函数（API函数），指定一个Hook类型、自己的Hook过程是全局还是局部Hook，同时给出Hook过程的进入点，就可以轻松的安装自己的Hook。
代码:
// 创建鼠标实例.
MouseHookProcedure = new HookProc(MouseHookProc);
//安装 鼠标hook
hMouseHook = SetWindowsHookEx(
WH_MOUSE_LL,
MouseHookProcedure,
Marshal.GetHINSTANCE(
Assembly.GetExecutingAssembly().GetModules()[0]),
0);

// 创建键盘实例.
KeyboardHookProcedure = new HookProc(KeyboardHookProc);
//安装 键盘hook
hKeyboardHook = SetWindowsHookEx(
WH_KEYBOARD_LL,
KeyboardHookProcedure,
Marshal.GetHINSTANCE(
Assembly.GetExecutingAssembly().GetModules()[0]),
0);
卸载Hook UnhookWindowsHookEx（）函数（API函数）

C# HOOK API，超复杂，建议你使用原生态的语言，比较说C++,Delphi，汇编等。
