整数n的阶乘指 1*2*3*...*(n-1)*n 的值，在n=171时，计算机一般会出错（“溢出”），本文采用字符串模拟数字乘法运算，使计算10000！成为可能：
Function multi(ByVal X As String, ByVal Y As String) As String 'multi of two huge hexnum（两个大数之积）Dim result As VariantDim xl As Long, yl As Long, temp As Long, i As Longxl = Len(Trim(X))yl = Len(Trim(Y)) ReDim result(1 ...

与笔者的另一算法（http://www.csdn.net/Develop/read_article.asp?id=28306）相比，采用下面的方法，阶乘的计算速度快了好几倍！

对于一般的整型数字，16进制与10进制 间的转化可以用CLNG（），HEX（）函数解决，但遇上天文数字，这些函数就无能为力了。下面是笔者写的几个函数，演示了天文数字计算中的一些技巧。

文本框属性为允许多行显示时，由于是软回车实现的分行，无法用SPLIT(TEXT1.TEXT,VBCRLF)准确地取出指定行的内容。本文利用SENDMESSAGE 系列函数，通过发送文本框消息，实现了获取包含指定字符串的行，并演示了如何获取文本框中文本总行数和任意指定行的文本内容。

动态数组在VB语言中常能起到出奇制胜的作用。但数组有没有被重新定义或释放，用“is empty”，“is null”，“=" "”等方法都不起作用。所以判断时一般采用侦别错误消息（ON ERROR ）的方法。下面给出一个非错误侦别的代码，判断动态字符串数组的分配情况：
Private Sub Command1_Click()Dim a() As String, i As Long
MsgBox hasredim(a), 64, "Has a() been redimed?" '未初始化
ReDim a(20)
For i = 1 To ...

福利彩票和体育彩票近两年比较火暴，相应在VB论坛上大家讨论也较多。其实选择彩票与集合选择子集相同道理。下面给出一种VB的递归算法（虽然明知存入数组会加快运算速度，但最终也没能满意地实现，请大家多多指教。另外，效率确实不高）Option Explicit
