做程序員2年了，感覺視力越來越差。有時候常常工作到忘記休息。于是就想寫一個能夠定時提醒的小東西(公司不讓從網絡下載別的程序)。
功能:
??? 1.能夠每隔一段時間提醒我休息，做做眼保健操。
??? 2.能夠自己設定時間間隔.
???
運行環境：.net framework 2.0

使用說明:
雙擊托盤 重新設定。
右鍵托盤 可以推出程序。
主界面如圖，

?

能夠設定提醒的時間間隔，以秒記，我一般設置為1800，半個小時,默認為半個小時。
設定后點擊ok，關閉主窗口，任務欄會有個托盤。

實現原理：

啟動一個新線程，讓其sleep所設置的時間間隔的長度，然后彈出對話框。

下面是代碼文件：只有一個類TimeNotifier

有三個PartialClass? TimeNotifier.cs, ?TimeNotifier.event.cs,TimeNotifier.Designer.cs
