介绍 TaskManager是一个个人信息管理器(PIM)。它是一个用于管理任务、事件、联系人、收藏夹和web链接等任何类型的个人信息的工具，这些信息都可以在同一个表单上浏览。它可以作为一种思维刺激器，一种自我分析和自我提升的工具。 在TaskManager中，不使用数据库;所有相关信息都存储在XML文件中。它可以是两个XML文件互操作性的最佳示例之一。 我们不需要安装数据库来使用这个应用程序。 主要有三个部分: 任务管理:对挂起的任务发出警报。添加，删除，编辑和导出任务列表作为HTML或Excel文件。要添加或编辑任务列表，需要单击左侧窗格中的任务按钮。 所有挂起的任务都将在托盘图标中显示为工具提示。单击工具提示，用户可以显示主表单。 联系人管理:以树状视图查看联系人，导航方便，添加和删除联系人。为所有联系人创建组。 Internet收藏夹:从Internet Explorer收藏夹列表中获取所有文件夹和链接，并将其显示为树状视图。导航喜爱的节点并在相同表单的web浏览器中显示该页面。一旦安装了应用程序，它将在运行时获取收藏夹。 使用的代码 我试着让它不言自明，等级分明。主要类是:TreeViewSerializer。ContactForm cs。cs, TaskManagerForm.cs。 下面的方法将负责在TaskList XML文件的任务表中添加一个任务。 隐藏,收缩,复制Code

/// <summary>
/// Utility method to update the visual representation of
/// the tasks (the CheckedListBox) with a new or updated row.
/// </summary>
/// <paramname="rowIndex">Index of modifed row, or -1 for new row</param>
/// <paramname="row">Row object from the DataTable</param>
private void UpdateDisplayWithRow(int rowIndex, TasksDataSet.TasksRow row)
{
    string title, format = "{0} - Due: {1:d}";

    title = string.Format(format, row.TaskTitle, row.TaskDueDate);

    if (rowIndex == -1)
    {
        tasksCheckedListBox.Items.Add(title, row.TaskComplete);
    }
    else
    {
        // Remove the old value, add a new one, set the checkbox
        tasksCheckedListBox.Items.RemoveAt(rowIndex);
        tasksCheckedListBox.Items.Insert(rowIndex, title);
        tasksCheckedListBox.SetItemChecked(rowIndex, row.TaskComplete);
    }
}

/// <summary>
/// Loads the entries using XML deserialization
/// </summary>
public void LoadEntries()
{
    try
    {
        XmlSerializer s = new XmlSerializer(typeof(TasksDataSet));
        TextReader r = new StreamReader("TaskList.xml");
        ds = (TasksDataSet)s.Deserialize(r);
        r.Close();

    }
    catch
    {
        ds = new TasksDataSet();
    }

    foreach (TasksDataSet.TasksRow row in ds.Tasks)
    {
        UpdateDisplayWithRow(-1, row);
    }
}

/// <summary>
/// Saves the entries using XML serialization
/// </summary>
public void SaveEntries()
{
    try
    {
        XmlSerializer s = new XmlSerializer(typeof(TasksDataSet));
        TextWriter w = new StreamWriter("TaskList.xml");
        s.Serialize(w, ds);
        w.Close();
    }
    catch( Exception x )
    {
        appNotifyIcon.ShowBalloonTip(8000,
            "Bh@nu's - Task Manager",
            "Tasks could not be saved.
" + x.Message, ToolTipIcon.Error);
    }
}

checktaskdate()方法将检查任务列表中任务的到期时间。所有悬而未决的任务每分钟都会以工具提示的形式显示在托盘图标上。 隐藏,收缩,复制Code

/// <summary>
/// Scans the list of tasks. Any incomplete tasks due
/// yesterday or earlier are appended to a buffer for
/// display in the tooltip.
/// </summary>
private void CheckTaskDates()
{
    // StringBuilder is more efficient than string concatentation
    StringBuilder buffer = new StringBuilder();

    // Iterate over each task in the DataSet
    foreach (TasksDataSet.TasksRow row in ds.Tasks)
    {
        // Compare date and completed flag
        if ((DateTime.Now.Date > row.TaskDueDate) && !row.TaskComplete)
        {
            buffer.Append(row.TaskTitle).Append(", Due: ");
            buffer.AppendFormat("{0:d}", row.TaskDueDate).Append('
');
        }
    }

    // If the buffer is not empty, there is at least one
    // task to display
    if (buffer.Length > 0)
    {
        // Display an Info balloon tip for 8 seconds
        appNotifyIcon.ShowBalloonTip(8000, 
            "bh@nu's - Task Manager", 
            buffer.ToString(), ToolTipIcon.Info);
    }
}

ContactForm类中还有另一个重要的方法。这个方法将负责在两个XML文件中添加新的联系人及其惟一的组和ID。一个XML文件将包含treeview数据，另一个文件将包含详细信息。为了便于显示treeview，我创建了这两个XML文件。 隐藏,收缩,复制Code

    //       Application.StartupPath + "\..\..\bhanu.xml");
    objTreeViewSerializer.SerializeTreeView(this.treeView_Contacts, 
                          Application.StartupPath + "\bhanu.xml");
