低级鼠标勾子的问题

listhome 2010-07-19 11:39:50

大家好，我用C#写了一个全局勾子，用于得到鼠标事件，鼠标事件可以拿到，但是每次点设置勾子的那个窗体的“最大化”，“最小化”，“关闭”按钮，应程都要是死一下。请问大家遇到过这种情况吗
设置鼠标勾子的代码



  // Make sure we keep a reference to this delegate!

                // If not, GC randomly collects it, and a NullReference exception is thrown

                _hookCallback = new WinAPI.HookProc(HookCallbackProcedure);



                Process curProcess = Process.GetCurrentProcess();

                ProcessModule curModule = curProcess.MainModule;



              





                _handleToHook = WinAPI.SetWindowsHookEx(

                    WH_MouseHook_LL,

                    _hookCallback,

                    curModule.BaseAddress,

                    0);







                // Were we able to sucessfully start hook?

                if (_handleToHook == 0)

                {

                    throw new InvalidOperationException("设置全局钩子失败" + Marshal.GetLastWin32Error());

                }

调用的代码





 public partial class Form1 : Form

    {

        GlobalHook hook = new MouseHook();

        

        public Form1()

        {

            InitializeComponent();

        }



        private void button1_Click(object sender, EventArgs e)

        {

            hook.Start();

           

        }



        private void button2_Click(object sender, EventArgs e)

        {

            hook.Stop();

           

        }



        private void Form1_Load(object sender, EventArgs e)

        {



        }

    }
