星期日
看完了书，看完了RSS订阅的新闻，刷完了微博，看完了电影，代码永远是有Bug的。好像没有事情可干了（嗯，其实还是有很多事情要做的，只是提不起兴致
）
我的这个周末过得是有多索然无味
翻翻自己的电脑，无意中找出以前的一个电脑桌面日历小程序，是用C#做的，还可以显示温度哦，还蛮有意思的O(∩_∩)O~~
首先呢，新建一个Visual C#窗体应用程序frmBrowser.cs。在窗体中添加1个Tooltrip控件，如下图所示：
再按照上面的方法依次添加1个Panel控件、5个Label控件和6个LinkLabel控件。依次修改各个控件的Backcolor属性、
Name属性和Text属性，上述工作完成了之后就可以得到这样的界面啦：
接下来就是最关键的工作啦：给每个控件事件响应添加程序~~
