【机房收费系统】金额返回信息查询

金额返回信息查询逻辑其实是和收取金额查询是一样的。都是

1.先判断起始日期和终止日期的关系：终止日期不能早于起止日期。

2.金额返回信息记录的判断，cancelcard表记录的查询，有记录和没有记录结果

3.查询成功

此窗体的目的：在机房收费系统中，操作员或者管理员需要查看退卡人的相关信息， 所以出现了这个窗体，主要功能是查询任意时间段内退卡人的信息。

代码展示：

 Dim txtsql, msgtext As String
    Dim mrc As ADODB.Recordset
    txtsql = "select * from cancelcard_info where date >= '" & DTPicker1.Value & "' and date <='" & DTPicker2.Value & "'"
    Set mrc = executeSQL(txtsql, msgtext)
    
    If DTPicker2.Value < DTPicker1.Value Then
        MsgBox "终止日期不能早于起止日期！", vbOKOnly + vbExclamation, "提示"
        Exit Sub
    
    Else
        
        If mrc.EOF = True Then
        MsgBox "没有数据记录！", vbOKOnly + vbExclamation, "提示"
        Exit Sub
        End If
    End If
    With MSHFlexGrid1
        .rows = 1
        .cols = 7
        .CellAlignment = 4
        '设置第一行的标题
        .TextMatrix(0, 0) = "卡号"
        
        .TextMatrix(0, 1) = "退还金额"
        .TextMatrix(0, 2) = "退还日期"
        .TextMatrix(0, 3) = "退还时间"
        .TextMatrix(0, 4) = "结账教师"
        .TextMatrix(0, 5) = "结账状态"
     
    Do While Not mrc.EOF
        .rows = .rows + 1
        .CellAlignment = 4
        .TextMatrix(.rows - 1, 0) = Trim(mrc.Fields(1))
        .TextMatrix(.rows - 1, 1) = Trim(mrc.Fields(2))
        .TextMatrix(.rows - 1, 2) = Trim(mrc.Fields(3))
          .TextMatrix(.rows - 1, 3) = Trim(mrc.Fields(4))
        .TextMatrix(.rows - 1, 4) = Trim(mrc.Fields(5))
        .TextMatrix(.rows - 1, 5) = Trim(mrc.Fields(6))
       
        mrc.MoveNext
    Loop
    End With
        MsgBox "查询成功！", vbOKOnly + vbExclamation, "提示"
    mrc.Close
