  说明:通过随机产生密码,然后将密码EMail给注册用户,你可以确认用户的EMail填写是否正确。自动产生的密码往往安全性更高,同时,你可以过滤那些无效的用户。
   把下面的代码保存为random.asp文件:

<%
Sub StrRandomize(strSeed)
   Dim i, nSeed
   nSeed = CLng(0)
   For i = 1 To Len(strSeed)
     nSeed = nSeed Xor ((256 * ((i - 1) Mod 4) * AscB(Mid(strSeed, i, 1))))
   Next

  Randomize nSeed
End Sub

Function GeneratePassword(nLength)
   Dim i, bMadeConsonant, c, nRnd

  Const strDoubleConsonants = "bdfglmnpst"
   Const strConsonants = "bcdfghklmnpqrstv"
   Const strVocal = "aeiou"

  GeneratePassword = ""
   bMadeConsonant = False

  For i = 0 To nLength
     nRnd = Rnd
     If GeneratePassword <> "" AND (bMadeConsonant <> True) AND (nRnd < 0.15) Then
       c = Mid(strDoubleConsonants, Int(Len(strDoubleConsonants) * Rnd + 1), 1)
       c = c & c
   i = i + 1
       bMadeConsonant = True
     Else
       If (bMadeConsonant <> True) And (nRnd < 0.95) Then
         c = Mid(strConsonants, Int(Len(strConsonants) * Rnd + 1), 1)
         bMadeConsonant = True
       Else
         c = Mid(strVocal,Int(Len(strVocal) * Rnd + 1), 1)
         bMadeConsonant = False
       End If
     End If
     GeneratePassword = GeneratePassword & c
   Next

  If Len(GeneratePassword) > nLength Then
     GeneratePassword = Left(GeneratePassword, nLength)
   End If
End Function
%>


   然后在你的目标程序中这样调用上面的代码,就可以实现密码的自动生成:(仅仅是一个例子,你可以把他们粘贴到一个Test.asp的文件中,然后运行Test.asp)

<!--include file="random.asp" -->
