桌面日历(阴历、天气)小程序

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

2014/3/30 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~~
