    <script laguage="VB" runat="server">
    Dim myConnection As OleDbConnection
    Dim myCommand As OleDbCommand
    sub page_load(sender as Object,e as EventArgs)

    @#1.连接数据库
    dim dbname as string
    dbname=server.mappath("authors.mdb")
    myConnection = New OleDbConnection( "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source="&dbname )
    myConnection.Open()
    la1.text="Connection Opened!"
