实例编程：用ASP.Net和Access编写留言本

　1、用Access建造一个数据库data.mdb，建立表Guest,结构如下:

　　ID 自动编号
　　标题 字符串
　　署名 字符串
　　正文 备注。

  2、guest.aspx

 %@ Import Namespace="System.Data" %
  %@ Import Namespace="System.Data.OleDb" %
  htmlhead
  style
  !--
  body{font-size:9pt}
  p{font-size:9pt}
  td{font-size:9pt}
  //--
  /style
  title留言本/title/head
  body
  p align=rightfont size=6留言本/font/p
  script language=vb runat=server
  Sub Page_Load(Source As Object, E As EventArgs)
   Dim myConn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0 ;Data Source=" & server.mappath("data.mdb"))
   Dim myAdapter As New OleDbDataAdapter
   Dim myOleDbCommandBuilder As OleDbCommandBuilder = New OleDbCommandBuilder(myAdapter)
   Dim DS As DataSet = New DataSet
   myAdapter.SelectCommand = new OleDbCommand("select ID, 标题, 署名 from Guest order by id desc", myconn)
   myconn.open()
   myAdapter.Fill(ds, "Guest")
   ml.DataSource=ds.Tables("Guest").DefaultView
   ml.DataBind()
  end sub
  /script
   ASP:DataGrid id="ml" runat="server"
   Width="100%"
   BorderColor="black"
   ShowFooter="false"
   CellPadding=3
   CellSpacing="0"
   Font-Name="宋体"
   Font-Size="9pt"
   HeaderStyle-BackColor="#ddaacc"
   EnableViewState="false"
  
  Columns
   asp:HyperLinkColumn
   DataNavigateUrlField="id"
   DataNavigateUrlFormatString="see.asp？id={0}"
   text="See!"
   Target="_new"
   /
  /Columns
  
  /asp:DataGrid
  brbrfont size=5我要留言/fontbr
  form method=post action=send.aspx
  标题:input type=text name=titlebr
  署名:input type=text name=namebr
  内容:textarea name=body/textareabr
  input type=submit
  /form 

    3、send.aspx

  %@ Import Namespace="System.Data" %
  %@ Import Namespace="System.Data.OleDb" %
  script language=vb runat=server
  Sub Page_Load(Source As Object, E As EventArgs)
   Dim myConn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0 ;Data Source=" & server.mappath("data.mdb"))
   Dim myInsertQuery As String = "insert into guest (标题, 署名, 内容) values (@#" & request("title") & "@#, @#" & request("name") & "@#, @#" & request("body") & "@#)"
   Dim myOleDbCommand As New OleDbCommand(myInsertQuery)
   myOleDbCommand.Connection = myConn
   myConn.Open()
   myOleDbCommand.ExecuteNonQuery()
   myOleDbCommand.Connection.Close()
   response.redirect("guest.aspx")
  end sub
  /script  

  4、see.asp（显示单个数据不如用ASP）

  htmlhead
  style
  !--
  body{font-size:9pt}
  p{font-size:9pt}
  td{font-size:9pt}
  //--
  /style
  title察看留言/title/head
  body
  p align=rightfont size=6察看留言/font/p
  %
  id=request("id")
  set cn=server.createobject("ADODB.CONNECTION")
  cn.open "DBQ=" + server.mappath("data.mdb") + ";DefaultDir=; DRIVER={Microsoft Access Driver (*.mdb)};"
  set rs=server.createobject("adodb.recordset")
  rs.open "select * from guest where id=" & id , cn
  %
  ID:% = id %BR
  标题:% = rs("标题") %br
  署名:% = rs("署名") %br
  内容:Br% = rs("内容") %br
  a href="guest.aspx"返回/a
