实现上述功能的VB程序如下：

Private Sub Command1_Click()

  List1.Clear

  Dim five(1 To 5) As Integer

  Dim i As Integer, j As Integer, k As Integer

  Dim p As Integer, find_pair As Boolean

  '随机抽取5张牌，将牌的点数存储在数组five中，并在List1中显示。代码略

  i = 5: p = 1: find_pair = False

  Do While i>= 2

    j=p

    Do While j <= i - 1

      If five(j) > five(j + 1) Then

        t = five(j): five(j) = five(j + 1): five(j + 1) = t

      ElseIf five(j) = five(j + 1) And Not find_pair Then

        t = five(1): five(1) = five(j): five(j) = t

        t = five(2): five(2) = five(j + 1): five(j + 1) = t

        find_pair = True

        i = i + 1

        p = _____________

        Exit Do

      End If

      j = j + 1

    Loop 

    i = i - 1

  Loop

  k = 0

  For i = 3 To 4

    If  Then k = k + 1

  Next i

  If five(1) = five(2) And k = 2 Then

    Label1.Caption = "运气不错:)"

  Else

    Label1.Caption = "运气一般:|"

  End If

End Sub
