'********************************************************************************************
'建一个类，类名为clsDate
Option Explicit
' 作 者 的 话
'
' clsDate本来是我在写一个软件的时候,因为需要,而且自已也想实作一个公农历的模块,因此就
' 写了它。2003年我将它发表在CSDN上，开始没有什么人注意，但是后来发现很多人写信给我说很不错，
' 我终于了解到了它的意义。所以也就打算一直把它维护下去。
'
' 因为我也是看到一个JSP的开源代码，我才了解它的原理，因此我也把这个小东东的源码公开了，
' 希望大家能够喜欢它。在这个类里有两个比较重要的问题需要解决，当你理解了它们，你就理解这个类
' 1、如何在VB中初使化数组数据
' 我采用的方式是 mydata =Array( , , , , )
' 或许你有更好的方法，虽然我也曾经想到用资源的方案，但是我觉得用户需要将资源导来导去，在
' 使用中会很不方便。
' 2、VB中的位操作是如何的
' 在1.0版中，也就是我发表在CSDN上的版本，其中需要一个Bit4VB.DLL的动态库，我是用C写的，
' 因为大家说VB是不能做位操作的，呵呵，我也没有去考虑那么多，就写了一个动态库。结果很多网友来信
' 有很大一半是要这个DLL的。
' 当我阅读Hardcore VB时，我才发现原来VB也是可以进行位操作的。如果计算到动态库的载入和接口处
' 理的花费的话，其实VB来写一个位操作的函数并不比用C来写慢多少。因此我实作出mvarBitTest32这个函数
' 在1.02中你再也不需要任何的DLL来支持这个类了。
'
'
'
' 最后我希望你能抽一点点时间给我写一封信，让我知道你在用它。让我有信心继续维护它。
'
' E-mail: liuxiaoshi@xtcz.net zhenghesoft@hotmail.com
'
'

' 版本预告：
' 下次我将推出 VB.net 和VB 6.0两个平台的版本。
' 将实现 1900-2100年的公农历转换
' 将一些方法和属性重新更名，但原有的接口将继续保持。
'
' 版本历史:
' 更新版本请注意CSDN上的更新
'
'
' 版本1.02 2004-4-15
' 考虑到用动态DLL的方案并不能真正提高位操作的速度,
' 而且受到Hardcore VB 作者的启示,已实作出速度很快的VB位操作模块,因此不再使用Bit4VB.DLL
' 在这个版本中只需要一个clsDate便真正可以完成公农历的转换,不需要其它任何的模块
'
' 版本 1.01 2004-2-10
' 增加了可以返回星期几字样的函数,sWeekDayStr
' 原来的sWeekDay 仍继续使用,以保证其它用户
'
'
'
'
' 注 意 事 项
'
' ///////////////////////////////////////////////////////////////////////////////
' // //
' // //
' // 说明:本模块仅能用于1900.1.31日起至 2049.12.31日止的数据转换,否则会出错。 //
