VBA窗体之ListBox
实现窗体如下:
窗体代码如下:
Option Explicit '声名模块级变量 Dim cnn As ADODB.Connection Dim rst As ADODB.Recordset '是否变量空间、关闭数据库连接、关闭窗体 Private Sub btnClose_Click() cnn.Close Set rst = Nothing Set cnn = Nothing Unload Me End Sub '列表框ListDept单击事件,查询部门员工 '提取员工的编号和姓名 Private Sub ListDept_Click() Dim sql As String sql = "select distinct 编号,姓名 from 员工 where 部门='" & ListDept.Value & "' order by 编号 asc" rst.Open sql, cnn, adOpenKeyset, adLockOptimistic Dim i As Integer With ListEmp .Clear For i = 1 To rst.RecordCount .AddItem rst("编号") & Space(2) & rst("姓名") rst.MoveNext Next End With rst.Close End Sub '将员工信息填入 textbox Private Sub ListEmp_Click() Dim i As Integer, IDStringCut As String Dim arr, brr Dim sql As String IDStringCut = Mid(ListEmp.Value, 1, InStr(ListEmp.Value, Space(2)) - 1) sql = "select * from 员工 where 编号='" & IDStringCut & "'" rst.Open sql, cnn, adOpenKeyset, adLockOptimistic '将每个字段的值存入空间 arr = Array("txtID", "txtName", "txtAge", "txtIDcard", "txtDate", "txtAddress", _ "txtDept", "txtJob", "txtEMail", "txtCV") brr = Array("编号", "姓名", "年龄", "身份证号", "聘用时间", "工作地", _ "部门", "职务", "电子邮件", "简历") For i = 0 To UBound(arr) Me.Controls(arr(i)).Value = rst(brr(i)) Next rst.Close End Sub '当窗体加载时,填写listDept Private Sub UserForm_Initialize() '建立数据库连接 Set cnn = New ADODB.Connection cnn_open cnn '提取不重复部门名称 Dim sql As String sql = "select distinct 部门 from 员工" '执行sql语句 Set rst = New ADODB.Recordset rst.Open sql, cnn, adOpenKeyset, adLockOptimistic '将记录集中的部门显示到 listDept 列表框中 Dim i As Integer With ListDept .Clear '先清空再添加 For i = 1 To rst.RecordCount .AddItem rst("部门") rst.MoveNext '将记录集中的指针指向下一条记录 Next End With rst.Close End Sub Sub cnn_open(cnn) With cnn .Provider = "microsoft.ace.oledb.12.0" .ConnectionString = "data source=" & ThisWorkbook.Path & "\学生管理.accdb" .Open End With End Sub
