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" %>

<html><head>

<style>



</style>

<title>留言本</title></head>

<body>

<p align=right><font 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>

<br><br><font size=5>我要留言</font><br>

<form method=post action=send.aspx>

标题:<input type=text name=title><br>

署名:<input type=text name=name><br>

内容:<textarea name=body></textarea><br>

<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）

<html><head>

<style>



</style>

<title>察看留言</title></head>

<body>

<p align=right><font 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>
