我的桌面应用程序无法捕获跳转列表单击事件

我有一个桌面应用程序。我添加了跳转列表菜单。当我右键单击任务栏上的图标时,此菜单将显示在跳转列表中。问题是,当我点击菜单项时,它不执行任何操作(即,我的应用程序确实捕获它)。 我从以下链接获取代码并相应地进行自定义(注意:此代码跳转列表在我的电脑上也不起作用)。我正在使用Visual Studio 2013和Windows 10。

在Program.cs中,我添加了以下代码。

    [STAThread]
    private static void Main()
    {
        bool firstInstance = false;
        Mutex mtx = new Mutex(true, "Jumplist.demo", out firstInstance);

        if (firstInstance)
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new frmSelect());
        }
        else
        {
            // Send argument to running window
            HandleCmdLineArgs();
        }

    }

    public static void HandleCmdLineArgs()
    {
        if (Environment.GetCommandLineArgs().Length > 1)
        {
            switch (Environment.GetCommandLineArgs()[1])
            {
                case "-1":
                    MessageBox.Show(@"-1");
                    break;
                case "-2":
                    MessageBox.Show(@"-2");
                    break;
                case "-3":
                    MessageBox.Show(@"-3");
                    break;
            }
        }
    }
}

Myjumplist类有以下代码

public class MYJumpList
{
    private JumpList jumpList;


    /// <summary>
    /// Creating a JumpList for the application
    /// </summary>
    /// <param name="windowHandle"></param>
    public goJumpList(IntPtr windowHandle)
    {
        TaskbarManager.Instance.ApplicationId = "MyJumplist";
        jumpList = JumpList.CreateJumpListForIndividualWindow(TaskbarManager.Instance.ApplicationId, windowHandle);
        jumpList.KnownCategoryToDisplay = JumpListKnownCategoryType.Recent;
        BuildList();
    }

    public void AddToRecent(string destination)
    {
        jumpList.AddToRecent(destination);
        jumpList.Refresh();
    }

    /// <summary>
    /// Builds the Jumplist
    /// </summary>
    private void BuildList()
    {
        JumpListLink jlItem1 = new JumpListLink(Assembly.GetEntryAssembly().Location, "Item1");
        jlItem1.Arguments = "-1";

        JumpListLink jlItem2 = new JumpListLink(Assembly.GetEntryAssembly().Location, "Item2");
        jlItem2.Arguments = "-2";

        JumpListLink jlItem3 = new JumpListLink(Assembly.GetEntryAssembly().Location, "Item3");
        jlItem3.Arguments = "-3";

        jumpList.AddUserTasks(jlItem1);
        jumpList.AddUserTasks(jlItem2);
        jumpList.AddUserTasks(jlItem3);
        jumpList.AddUserTasks(new JumpListSeparator());
        jumpList.Refresh();
    }
}

我的主窗体构造函数具有以下跳转列表代码行

 jumpList = new MyJumpList(this.Handle);

我不知道哪里出错了。 请给我任何帮助,以便在我的申请中应用跳转列表

随着更多的研究和奋斗,我重新安排了代码,最后我能够在2013和Windows 10中使用跳转列表。 在Program.cs中,我使用了以下代码。

    private static void Main(string[] args)
    {
        if (args.Any())
        {
            try
            {
                var proc = Process.GetCurrentProcess();

                Process[] processes = Process.GetProcessesByName(proc.ProcessName);

                if (processes.Length > 1)
                {
                    //iterate through all running target applications      
                    foreach (Process p in processes)
                    {
                        if (p.Id != proc.Id)
                        {
                            if (args[0] == "Item1")
                                SendMessage(p.MainWindowHandle, Item1Value, IntPtr.Zero, IntPtr.Zero);
                            if (args[0] == "Item2")
                                SendMessage(p.MainWindowHandle, Item2Value, IntPtr.Zero, IntPtr.Zero);
                            if (args[0] == "Item3")
                                SendMessage(p.MainWindowHandle, Item3Value, IntPtr.Zero, IntPtr.Zero);

                            Environment.Exit(0);
                        }
                    }
                }
            }
            catch (Exception)
            {


            }
        }

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        if (args.Any())
        {
            if (args[0] == "Item1") Application.Run(new frmSelect(Item1Value));
            if (args[0] == "Item2") Application.Run(new frmSelect(Item2Value));
            if (args[0] == "Item3") Application.Run(new frmSelect(Item3Value));
        }
        else
        {
            Application.Run(new frmSelect());
        }


    }

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr SendMessage(IntPtr hwnd, uint Msg, IntPtr wParam, IntPtr lParam);
    private const int Item1Value = 0xA123;
    private const int Item2Value = 0xA124;
    private const int Item3Value = 0xA125;
}

我的主要表单显示方法有以下代码

    private void frmSelect_Shown(object sender, EventArgs e)
    {
        var appPath = Assembly.GetEntryAssembly().Location;
        var jumpList = JumpList.CreateJumpList();
        var category = new JumpListCustomCategory("MyApp");

        category.AddJumpListItems(
            new JumpListLink(appPath, "Item1") {Arguments = "Item1"},
            new JumpListLink(appPath, "Item2") {Arguments = "Item2"},
            new JumpListLink(appPath, "Item3") {Arguments = "Item3"});

        jumpList.AddCustomCategories(category);
        jumpList.Refresh();
    }

我的主窗体中的WndProc方法有以下代码

    protected override void WndProc(ref Message message)
    {
        if (message.Msg == Item1Value) messagebox.show("Item1 Clicked"); // here we can call relevant method
        if (message.Msg == Item2Value) messagebox.show("Item2 Clicked"); // here we can call relevant method
        if (message.Msg == Irem3Value) messagebox.show("Item3 Clicked"); // here we can call relevant method

        base.WndProc(ref message);
    }

我希望任何人都可以使用这个简单的方法在应用程序中使用跳转列表。
