vb 操作access数据库

[sduupc]

有一个vb操作数据库的例子，想改成操作access2000以上版本的，数据库不怎么熟悉，不会改了，
大家给看看吧，谢了！该例用的是data控件和dbgrid控件，想改成使用DAO3.6对象或者ADO的都可以，实现
相同点功能。
Option Explicit
Dim db As Database '一个DAO对象

Private Sub Command1_Click() '选择一个数据库
With CommonDialog1
.Filter = "数据库文件(*.mdb)|*.mdb"
.ShowOpen
End With
Text1.Text = CommonDialog1.FileName
displaytable
End Sub



Private Sub Form_Load() '初始化界面
Dim dbname As String
Adodc1.Visible = False
DataGrid1.Visible = False
Set DataGrid1.DataSource = Adodc1
dbname = App.Path
If Right$(dbname, 1) <> "\" Then dbname = dbname & "\"
dbname = dbname & "19.mdb"
Text1.Text = dbname
displaytable

End Sub




Private Sub List1_Click() '显示选择的表中的数据
Dim table_name As String
Dim sql As String
table_name = List1.List(List1.ListIndex)
sql = "SELECT * FROM " & table_name
Adodc1.Caption = table_name
Adodc1.RecordSource = sql
Adodc1.Refresh
Adodc1.Visible = True
DataGrid1.Visible = True
End Sub
Private Sub displaytable() '显示选择的数据库中的表名
Dim td As TableDef
Set db = OpenDatabase(Text1.Text)
List1.Clear
For Each td In db.TableDefs
If td.Attributes = 0 Then '仅仅显示用户表，不显示系统表
List1.AddItem td.Name
End If
Next td
db.Close
Adodc1.DatabaseName = Text1.Text
End Sub

就是用ADODC和datagrid来替换DATA和dbgrid控件，再改改源码

或者给个将数据库中的表显示在列表里，点击显示表内的内容的例子也可以！

Option Explicit
    Dim tabelName(50) As String
    Dim i As Integer
    Dim l As Integer

Private Sub Combo1_Click()
    Text1 = Combo1
End Sub

Private Sub Command1_Click()
    Dim fileN As String
    CommonDialog1.ShowOpen
    fileN = CommonDialog1.FileName
    Dim cn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Set cn = New ADODB.Connection
    cn.Open "Provider=Microsoft.Jet.OLEDB.4.0; " _
    & "Data Source=" & fileN & ";" _
        & "Persist Security Info=False;" _
        & "Jet OLEDB:Database Password=123"
    Set rs = New ADODB.Recordset
    Set rs = cn.OpenSchema(adSchemaTables, _
        Array(Empty, Empty, Empty, "TABLE"))
    While Not rs.EOF
        tabelName(i) = rs!TABLE_NAME
        i = i + 1
        rs.MoveNext
    Wend
    rs.Close
    cn.Close
    l = i - 1
    For i = 0 To l
        Combo1.AddItem tabelName(i)
    Next
End Sub

Private Sub Form_Load()
    Text1 = ""
    Combo1 = ""
End Sub

是依据vbman2003的代码将ACCESS数据库的表名放入ComboBOX显示.

我喜欢老版的 能向下兼容~

为DataGrid指定Adodc确实更为方便。
