WPF-006：判断当前是否有人操作

检测当前程序是否有人操作应该再实际中还是有用的。最简单的方法时判断鼠标位置是否改变了。winform中也是一样。直接看代码：

public class CheckUsedManager    {         public static event EventHandler TimeToFinishedEvent = null;        private static DispatcherTimer checkUsedTimer = new DispatcherTimer();        private static Point mousePosition = GetMousePoint();        static CheckUsedManager()        {            checkUsedTimer.Interval = TimeSpan.FromSeconds(秒数);            checkUsedTimer.Tick += new EventHandler(CheckUsedTimer_Tick);            checkUsedTimer.Start();        }        static void CheckUsedTimer_Tick(object sender, EventArgs e)        {            if (!HaveUsedTo())            {                if (TimeToFinishedEvent != null)                {                    TimeToFinishedEvent(null, null);                }            }        }        private static bool HaveUsedTo()        {            Point point = GetMousePoint();            if (point == mousePosition)            {                return false;            }            mousePosition = point;            return true;        }        [StructLayout(LayoutKind.Sequential)]        private struct MPoint        {            public int X;            public int Y;            public MPoint(int x, int y)            {                this.X = x;                this.Y = y;            }        }        [DllImport("user32.dll", CharSet = CharSet.Auto)]        private static extern bool GetCursorPos(out MPoint mpt);        /// <summary>        /// 获取当前屏幕鼠标位置        /// </summary>        /// <returns></returns>        public static Point GetMousePoint()        {            MPoint mpt = new MPoint();            GetCursorPos(out mpt);            Point p = new Point(mpt.X, mpt.Y);            return p;        }    }

然后绑定到该类的事件即可。如下用WPF实现的完整代码：

判断的类：

public class CheckUsedManager    {         public static event EventHandler TimeToFinishedEvent = null;        private static DispatcherTimer checkUsedTimer = new DispatcherTimer();        private static Point mousePosition = GetMousePoint();        static CheckUsedManager()        {            checkUsedTimer.Interval = TimeSpan.FromSeconds(ReadConfig.AutoCheckUsedTime);            checkUsedTimer.Tick += new EventHandler(CheckUsedTimer_Tick);            checkUsedTimer.Start();        }        static void CheckUsedTimer_Tick(object sender, EventArgs e)        {            if (!HaveUsedTo())            {                if (TimeToFinishedEvent != null)                {                    TimeToFinishedEvent(null, null);                }            }        }        private static bool HaveUsedTo()        {            Point point = GetMousePoint();            if (point == mousePosition)            {                return false;            }            mousePosition = point;            return true;        }        [StructLayout(LayoutKind.Sequential)]        private struct MPoint        {            public int X;            public int Y;            public MPoint(int x, int y)            {                this.X = x;                this.Y = y;            }        }        [DllImport("user32.dll", CharSet = CharSet.Auto)]        private static extern bool GetCursorPos(out MPoint mpt);        /// <summary>        /// 获取当前屏幕鼠标位置        /// </summary>        /// <returns></returns>        public static Point GetMousePoint()        {            MPoint mpt = new MPoint();            GetCursorPos(out mpt);            Point p = new Point(mpt.X, mpt.Y);            return p;        }    }

读配置里的时间：

   public class ReadConfig    {        /// <summary>        /// 检测是否使用间隔时间        /// </summary>        public static int AutoCheckUsedTime        {            get            {                int time = 10;                try                {                    string timeStr =  ConfigurationManager.AppSettings["AutoCheckUsedTime"];                    if (string.IsNullOrEmpty(timeStr))                    {                        timeStr= "10";                    }                    time = int.Parse(timeStr);                }                catch { }                return time;            }        }    }

配置App.config：

<?xml version="1.0" encoding="utf-8" ?><configuration>  <appSettings>    <add key="AutoCheckUsedTime" value="10"/>  </appSettings></configuration>

界面调用：

public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();            CheckUsedManager.TimeToFinishedEvent -= new EventHandler(CheckUsedManager_TimeToFinishedEvent);            CheckUsedManager.TimeToFinishedEvent += new EventHandler(CheckUsedManager_TimeToFinishedEvent);        }        void CheckUsedManager_TimeToFinishedEvent(object sender, EventArgs e)        {            MessageBox.Show("无人使用！");        }    }
