MD5 加密算法 VB 实现代码
虽然现在MD5 加密算法严格来讲已经不算安全，但一般小功能或公司内部使用应该足够了
Attribute VB_Name = "modMd5"
' MODULE: CMD5

Option Explicit
Public Const BITS_TO_A_BYTE As Long = 8
Public Const BYTES_TO_A_WORD As Long = 4
Public Const BITS_TO_A_WORD As Long = BYTES_TO_A_WORD * BITS_TO_A_BYTE
Public m_lOnBits(0 To 30) As Long

' DESCRIPTION:
' We will usually get quicker results by preparing arrays of bit patterns and
' powers of 2 ahead of time instead of calculating them every time, unless of
' course the methods are only ever getting called once per instantiation of the
' class.

这一段大家编写程序很多时候都在使用API,它给我们带来了强大的功能.让我们非常惊喜.
但是我们在调试程序的时候有时候总会奔溃.这样很不方便.
其中有些是api惹的祸
使用api注意事项:
首先我说说我的观点.
1:Api是很多系统也在用.我们在设置参数时如果和系统的参数有冲突.就可能引起软件出错
2.api很多都是c语言编写的, ......

如果原来没有使用过正则表达式，那么可能对这个术语和概念会不太熟悉。不过，它们并不是您想象的那么新奇。
请回想一下在硬盘上是如何查找文件的。您肯定会使用 ? 和 * 字符来帮助查找您正寻找的文件。? 字符匹配文件名中的单个字符，而 * 则匹配一个或多个字符。一个如 'data?.dat' 的模式可以找到下述文件：
data1.dat
