  • 1. (2016·杭州模拟) 某商场元月举行VIP客户积分换购活动,VIP客户根据卡内积分多少可换取不同额度的代金券。假设VIP客户共有n名,VIP卡内积分存放在数据库“customer.accdb”的Integral表中,换购活动的VB程序代码如下,程序运行时界面如第7题图所示。工作人员在文本框Text1中输入VIP卡号后,单击“换购”按钮Command1,在文本框Text2中输出VIP客户的积分数,在标签Label3中显示可以换购的代金券额度,积分清零。按此要求编写程序如下, 但加框处代码有错,请改正。

    Dim ID( ) As String    '用于存放客户卡号

    Dim total( ) As Long      '用于存放积分数

    Dim sc As Long                  'VIP客户人数

    Dim jf As Long                  '积分数

    Private Sub Command1_Click( )

      Dim k As String                '客户卡号

      Dim q As Long               '代金券额度

      Dim i As Long

      k = Text1.Text

      For i = 1 To sc     ’顺序查找

          If ID(i) = k Then

              jf = total(i)     

              cash(jf) = q               ’ ①

              Exit For

          End If

          Text2.Text = Str(jf)

          Label3.Caption = “您可换购的代金券总额为:”+ Str(q) + “元”

        Next i

      End If

    End Sub

    ' cash函数用于计算VIP客户可换购的代金券额度

    Function cash(jf As Long) As Long

      If jf >= 2000 And jf <= 20000 Then

           Cash = jf\2000*10

    ElseIf jf > 20000 And jf <= 50000 Then

           Cash = jf\2000*11

    ElseIf jf > 50000 And jf <= 100000 Then

           Cash = jf\2000*12

    ElseIf jf > 100000 And jf <= 150000 Then

           Cash = jf\2000*13

     Else jf > 150000 Then         ’ ②

           Cash = jf\2000*14

    End If

    End Function

    Private Sub Form_Load()

       Dim conn As New ADODB.Connection, rs As New ADODB.Recordset

       Dim intSQL As Long

       conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + App.Path + "\ customer.accdb"

        conn.Open

       intSQL = "SELECT score  FROM Integral" 

         Set rs.ActiveConnection = conn

         rs.CursorType = adOpenStatic

         rs.Open intSQL

         sc = 0

         Do While Not rs.EOF

           sc = sc + 1

           total(sc) = rs.Fields("score")

           rs.MoveNext

         Loop

    rs.Close

         conn.Close

         Set rs = Nothing

         Set conn = Nothing

    End Sub
