通过 Notification 类 实现缩小窗体到任务栏
Notification此类提供 Windows CE 通知功能的托管实现。只有 Pocket PC 上支持此类。
您可以创建通知，然后使用 Visible 属性来根据需要显示它们。InitialDuration 属性设置消息气球最初显示的时间。如果将 InitialDuration 设置为零，并将 Visible 设置为 true，则消息气球不会显示，但是标题栏中会有它的图标，单击可以重新激活它。每当显示或隐藏气球时，无论是使用 Visible 属性以编程方式进行此操作，还是通过用户交互方式进行此操作，都会发生 BalloonChanged 事件。
除了纯文本之外，您还可以在消息气球中创建 HTML 内容的用户通知。HTML 由 Pocket PC HTML 控件来呈现；您可以通过 Response 属性分析 ResponseSubmittedEventArgs 类提供的响应字符串来响应 HTML 窗体中的值。
Cmd:2 标识符标识符“cmd:2”在 Windows CE 中具有特定的用途，用于关闭通知。如果 cmd:2 是消息气球中的 HTML 按钮或其他元素的名称，则不会引发 ResponseSubmitted 事件。通知被关闭了，但它的图标放置在标题栏上，以后还可以对它作出响应。
 注意 |
|---|
| 如果有一个链接或元素的名称为“cmd:n”（其中 n 可以是任意整数），则不会引发 ResponseSubmitted 事件。不过，建议只将 cmd:2 用作关闭通知的标识符。 |
