显示数据库文件使用TreeView,列表视图和ADO

介绍我有一个问题在我的电子邮件，“如何使用ADO来填充数据的树状视图和列表视图*。mdb文件?我试着用以下几句话来回答这个问题:我希望我能成功。这篇文章展示了如何: 连接数据库填充TreeView与表的名称和字段namePopulate ListView与记录的选择表背景演示项目有一种形式。我添加以下控件到我的表单(frmDataView): 两个标签(lblDatabase)显示文件名和(lblTableName)显示表名两个按钮，一个(cmdLoadData)连接数据库文件，另一个(cmdClose)结束showImageList (ImageList1)加载一些iconsTreeView (tvData)和ListView (lvData)。使用Code 隐藏,收缩,复制Code

' Here is the code to get Tables name from the database file:
Dim cn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim MyDataFile As String
Dim strCon As String
Dim tabName As String
Dim dbNode As Node
Dim tabNode As Node

   ' Don't use: On Error goto label, but use following:
   On Error Resume Next
   'set root node of TreeView.
   Set dbNode = tvData.Nodes.Add(, , "RootDB", "Database", "DatabaseClose")
   dbNode.Tag = "RootDB"
   MyDataFile = App.Path & "DataFile" & "test.mdb"
   strCon = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" & MyDataFile & ";"
   Set cn = New ADODB.Connection
   cn.CursorLocation = adUseClient
   cn.Open strCon
   Set rst = cn.OpenSchema(adSchemaTables)
   rst.MoveFirst
   Do Until rst.EOF
      If rst("TABLE_TYPE").Value = "VIEW" Or rst("TABLE_TYPE").Value = "TABLE" Then
         tabName = rst("TABLE_NAME").Value
         Set tabNode = tvData.Nodes.Add("RootDB", tvwChild, "X" & tabName, _
		tabName, "TableClose")
         tabNode.Tag = "Tables"
      End If
      rst.MoveNext
   Loop
   rst.Close

' Here is the code to get Fields name from all Tables:
Dim rs As ADODB.Recordset
Dim fldName As String
Dim n As Integer
Dim c As Integer
Dim i As Integer
Dim j As Integer
   Set rs = New ADODB.Recordset
   c = tvData.Nodes("RootDB").Children
   ' first table
   n = tvData.Nodes("RootDB").Child.FirstSibling.Index
   For i = n To c + n
      tabName = tvData.Nodes(i).Text
      ' get field name
      Set rs = cn.Execute("SELECT * FROM [" & tabName & "]", 1, 1)
      For j = 0 To rs.Fields.Count - 1
         fldName = rs.Fields(j).Name
         Set fldNameNode = tvData.Nodes.Add("X" & tabName, tvwChild, _
		"X" & fldName, fldName, "imgField")
         fldNameNode.Tag = "Fields"
      Next j
      rs.Close
   Next i

你可以在表格(frmDataView)中阅读完整的代码: InitListView子:初始化ListViewLoadListView子:加载ListView datacmdLoadData_Click子:联系数据库filetvData_Collapse子:改变icontvData_Expand子:改变icontvData_NodeClick子:看到如何填充ListView TreeView记录当单击表名称,你也可以看到我们如何更改图标ColumnHeader ListView 当点击TreeView的字段名讲话当你创建一个新的项目，你必须添加ListView, TreeView和imagels&ist控件到工具箱从组件对话框:Microsoft Windows通用控件6.0你必须添加引用:“Microsoft ActiveX数据对象2.x”。最后一句话我希望这篇文章是有用的，并帮助您显示表，字段和记录从数据库文件到TreeView和ListView。如果你有任何想法或发现任何问题，请告诉我。感谢CodeProject和所有人。 Mostafa KaisounM_Kaisoun@hotmail.com 历史 2009年10月18日:初任本文转载于：http://www.diyabc.com/frontweb/news2313.html
