c# - 我的桌面应用程序无法捕获跳转列表点击事件

Question

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，此菜单会出现在 Jumplist 中。问题是当我单击菜单项时，它没有执行任何操作（即，我的应用程序确实捕获了它）。我从以下链接获取代码并相应地对其进行了自定义（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。

http://www.codeproject.com/Articles/103913/How-to-Create-a-Custom-Jumplist-with-Custom-Events

在 Program.cs 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 类具有以下代码

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();
    }
}

我的主表单构造函数具有以下跳转列表代码行

 jumpList = new MyJumpList(this.Handle);

我不知道哪里错了。请给我任何帮助以在我的应用程序中应用跳转列表

经过更多的研究和努力，我重新排列了代码，最后我能够使跳转列表在 vs 2013 和 windows 10 中工作。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;
}

我的主要形式显示的方法有以下代码

    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();
    }

我的主要形式中的 WndProc 方法具有以下代码

    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应用这种简单的方法在应用程序中使用跳转列表。
