本文主要是介绍第一次机房收费系统之管理员显示值班教师，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
操作流程：
在窗体加载时直接显示数据。
使用数据库表：
worklog_info（存放用户上下机记录）
具体代码如下：
Option Explicit
Dim H As Single '定义窗体高的变量 '定义窗体高的变量
Dim W As Single '定义窗体高的变量 '定义窗体宽的变量Private Sub cmdOFF_Click()Unload frmDutyTeacher
End SubPrivate Sub Form_Load()H = Me.HeightW = Me.WidthWith MSHFlexGrid.Rows = 1.TextMatrix(0, 0) = "记录号".TextMatrix(0, 1) = "教师".TextMatrix(0, 2) = "级别".TextMatrix(0, 3) = "登录日期".TextMatrix(0, 4) = "登录时间".TextMatrix(0, 5) = "机器名"End With
End SubPrivate Sub Form_Resize()'对worklog_info表操作Dim mrcworklog As ADODB.Recordset '用于存放记录集Dim worklogSQL As String '用于存放SQL语句Dim worklogMsgText As String '用于存放返回信息worklogSQL = "select * from worklog_info where status='True'"Set mrcworklog = ExecuteSQL(worklogSQL, worklogMsgText)'查看是否存在WORKLOG的记录If mrcworklog.EOF = True ThenMsgBox "没有值班教师！", vbOKOnly + vbInformation, "提示"ElseWith MSHFlexGridDo While mrcworklog.EOF = False.Rows = .Rows + 1.CellAlignment = 4.TextMatrix(.Rows - 1, 0) = Trim(mrcworklog.Fields(0)).TextMatrix(.Rows - 1, 1) = Trim(mrcworklog.Fields(1)).TextMatrix(.Rows - 1, 2) = Trim(mrcworklog.Fields(2)).TextMatrix(.Rows - 1, 3) = Trim(mrcworklog.Fields(3)).TextMatrix(.Rows - 1, 4) = Trim(mrcworklog.Fields(4)).TextMatrix(.Rows - 1, 5) = Trim(mrcworklog.Fields(7))mrcworklog.MoveNextLoopEnd Withmrcworklog.CloseEnd IfMe.Height = HMe.Width = WMe.PaintPicture Me.Picture, 0, 0, Me.ScaleWidth, Me.ScaleHeight '实现背景图随窗体变大而改变
End Sub优化方面：
Dim H As Single '定义窗体高的变量 '定义窗体高的变量
Dim W As Single '定义窗体高的变量 '定义窗体宽的变量
Private Sub Form_Load()H = Me.HeightW = Me.Width
End SubPrivate Sub Form_Resize()Me.Height = HMe.Width = WMe.PaintPicture Me.Picture, 0, 0, Me.ScaleWidth, Me.ScaleHeight '实现背景图随窗体变大而改变
End Sub
