  写这个文章绝对是偶然的偶然的机会,前年等一回的 元旦节,和 老婆上街 溜达,猛然想起买上一张福利彩票,结果屁都没有中上,开春第一天,就写了个预测彩票中奖的程序,这其中的一个很关键的算法就是如何生成一个不重复的随即数字,大家看完这个程序以后如果中奖,千万不要忘记豆腐了呀:)

  Sub CalCaPiao()
  Dim strCaiPiaoNoArr() As String
  Dim strSQL As String
  Dim strCaiPiaoNo As String
  strCaiPiaoNo = "01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33"
  Dim StrTempArr(7) As String
  Dim strZhongJiangArr(7) As String
  strCaiPiaoNoArr = Split(strCaiPiaoNo, ",")
  Dim intRand As Integer
  Dim i As Integer
  Dim j As Integer
  i = 0
  Dim find As Boolean
  Do While True
  find = False
  Randomize
  intRand = Int((33 * Rnd) + 1)
  For j = 0 To i - 1
  If StrTempArr(j) = CStr(intRand) Then
  find = True
  End If
  Next
  If Not find Then
  StrTempArr(j) = CStr(intRand)
  strZhongJiangArr(i) = CStr(intRand)
  'Text1(i) = strZhongJiangArr(i)
  i = i + 1
  If i = 7 Then
  Exit Do
  End If
  End If
  Loop
  End Sub

  呵呵,过几天,我把这个程序搞成组件,放到我的站点上 大家一起来玩玩,呵呵!
