结账对于笔者也是一块新知识，首先是这个控件，他显示信息是什么原理，我就看了好多博客......

正文

如图，中间的控件叫做SSTab。 SSTab控件提供了一组选项卡，每个都充当一个容器，包含了其他的控件。

本窗体的运行原理是当我们选择操作员用户名后，显示操作员真实姓名。显示此人的工作记录在下面五个栏目中：购卡、充值、退卡、临时用户、汇总。

这里有个重点，计算总的售卡数，总的收款金额。我们计算时需要用到Val函数，把字符串型的代码转换成数值型。

代码实现全过程如下：

Private Sub comboid_Click()
'购卡
    Dim txtsql As String
    Dim msgtext As String
    Dim mrc As ADODB.Recordset

'查找管理员

    txtsql = "select * from User_Info where userID='" & comboid.Text & "'"
    Set mrc = ExecuteSQL(txtsql,msgtext)

    comboname.Text = mrc.Fields(3)
    mrc.Close

    txtsql = "select * from student_Info where UserID='" & comboid.Text & "'"
    Set mrc1 = ExecuteSQL(txtsql,msgtext)


 '显示购卡信息
    With MSFlexGrid1
        .Rows = 1
        .CellAlignment = 4
        .TextMatrix(0,0) = "学号"
        .TextMatrix(0,1) = "卡号"
        .TextMatrix(0,2) = "日期"
        .TextMatrix(0,3) = "时间"




    Do While Not mrc1.EOF
        .Rows = .Rows + 1
        .CellAlignment = 4
        .TextMatrix(.Rows - 1,0) = Trim(mrc1.Fields(1))
        .TextMatrix(.Rows - 1,1) = Trim(mrc1.Fields(0))
        .TextMatrix(.Rows - 1,2) = Trim(mrc1.Fields(12))
        .TextMatrix(.Rows - 1,3) = Trim(mrc1.Fields(13))
        
        mrc1.MoveNext
    Loop
        
        .Rows = .Rows - 1
        Text1.Text = Int(.Rows - 1)       '汇总:售卡张数
        
    End With
    mrc1.Close








'充值

    Dim mrcrecharge As ADODB.Recordset
    

'查找管理员

    txtsql = "select * from ReCharge_Info where userID='" & comboid.Text & "'"
    Set mrcrecharge = ExecuteSQL(txtsql,msgtext)


 '显示购卡信息
    With MSFlexGrid2
        .Rows = 1
        .CellAlignment = 4

        .TextMatrix(0,3) = "日期"

      Do While Not mrcrecharge.EOF
        .Rows = .Rows + 1

        .TextMatrix(.Rows - 1,1) = Trim(mrcrecharge.Fields(2))
        .TextMatrix(.Rows - 1,2) = Trim(mrcrecharge.Fields(3))
        .TextMatrix(.Rows - 1,3) = Trim(mrcrecharge.Fields(4))
        .TextMatrix(.Rows - 1,4) = Trim(mrcrecharge.Fields(5))
        
        Text3.Text = Val(.TextMatrix(.Rows - 1,2)) + Val(Text3.Text)  '汇总：充值金额
        
        mrcrecharge.MoveNext
