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>
<!--
body{font-size:9pt}
p{font-size:9pt}
td{font-size:9pt}
//-->
</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>
<!--
body{font-size:9pt}
p{font-size:9pt}
td{font-size:9pt}
//-->
</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>
