前几天下载了一个侧边栏日历,被它的界面所打动,试着想在自己的系统中也做一个。
想着容易,做起来就不是那么回事了,本身对历法知识知之甚少,结果被其中的初一、廿十、天干、地支、属相搞得晕头转向,更让人难于摆平的是节气,网上搜了半天发现都是简单的几句介绍,所留的计算式经过计算精确度太低,C++码源倒是有,可惜偶不懂^_^。
没办法,最后参考了一些资料只好自己动手,精确度应该说已经没有问题了。
为方便大家组合到自己的系统中,全部代码都放在了窗口AfterLoad事件中,大家只需将窗口存为模板后应用到自己的系统中即可。
本程序所支持节气期限:立春1900年到2399年,其他节气1900年到2199年,如发现有错请指正。
后语:
这个日历是个很不起眼的东东,但却是我最为得意之作,原因很简单,因为我做到了自以为不可能做到的事。
标题的“得意之作”为自娱自乐,大家别拍砖。
将代码做了下标注:
