ASP建站十大常用程序代码完整篇
这个教程我要分10篇给大家来做分析,这十大常用程序都包括什么呢?下面我给大家列出大纲工参考:第一节:注册系统注册几乎是每个网站都要使用的，去论坛要注册，聊天要注册，几乎无处不注册，所以注册是所有ASP应用程序中最常见的。
第二节:留言薄互联网最大的特点是互动性，让网友在留言薄上留下自己的意见能使网站的人气值上升不少。
第三节:调查系统利用网络进行一些调查是非常常见的，轻轻一点投下自己一票，因此有一个调查系统能为网站增色不少。
第四节:购物车购物车这个名字取自超级市场的购物推车，不过这个小小的推车却是每个购物网站必备的。
第五节:计数器在浏览网页的时侯，常常可以看见一些“当前网站上的人数是xxxx人”的在线人数统计。
第六节:论坛系统论坛可以说是网站中最受网友欢迎的地方，网友可以在这里自由的发表自己的意见，网站人气的高低很大程度上由论坛决定，因此为我们的网站增加一个论坛是必须的。
第七节:聊天室当你独自在Internet上浏览时，你并不是一个孤单的“旅人”，因为每时每刻总有成千上万的人同时在网上浏览，你可以同他们聊聊天，交谈几句，让自己体验一下“网”内存知己、天涯若比邻的感觉第八节:EMail当你独自在Internet上浏览时，你并不是一个孤单的“旅人”，因为每时每刻总有成千上万的人同时在网上浏览，你可以同他们聊聊天，交谈几句，让自己体验一下“网”内存知己、天涯若比邻的感觉。
第九节:搜索系统一个大型网站内容众多，来访者往往很难找到自己所需要的东西，这时候就需要一个站内搜索来帮助来访者更快的找到索要的资料，所以搜索系统是一个大型网站必备系统。
第十节:分页程序从程序上说分页只是一种小技巧，但确实却是一个非常重要的小技巧，好，少说废话，我们开始吧。
好了以上是我要给大家分别讲解的教程.欢迎大家及时收藏和支持这里先给大家讲解第一节:注册系统（一），设定注册页面的外观：在这个例子中涉及了五个页面，其中有三幅是一般的htm文件，另外的两幅是asp文件，在这里制作利用的工具是frontpage98，但是大部分的asp代码还是要自己输入的：1，设定原来已经注册的用户进入的外观：在这里设置了两个文本框，一个超级链接和两个按钮。

asp常用代码集锦
ASP中常用代码Cookie的用法：//Cookie的用法HttpCookie cookie = new HttpCookie("first"); //第一个Cookie cookie.Expires = DateTime.Now.AddDays(30); //设置Cookie的消失时间，时间为30天cookie.Values["name"] = "lsc"; //设置Cookie的值//name <-->lsc为键值对cookie.Values["password"] = "12345";Response.Cookies.Add(cookie); //将指定的Cookie保存到本机//获取Cookie的值HttpCookie c = (HttpCookie)Request.Cookies["first"];Response.Write(c.Values["name"] + "<br/>");Response.Write(c.Values["password"]);Application 的用法：写在Gloal.asaxvoidApplication_Start(object sender, EventArgs e){// Code that runs on application startup//服务器启动时运行的代码//关于计数器的使用//在此初始化计数器Application["count"] = 0; //当服务器启动时调用，该网站访问数为0开始}写在页面端protected void Page_Load(object sender, EventArgs e) {try{//取出application中的值|Application.Lock();int count = (int)Application["count"];count++;Application["count"] = count; //将此返回服务?器Response.Write("你是第+Application["count"] + "位访客¨a");Application.UnLock();}catch (Exception ex){Response.Write(“<script>alert(“+ex.Message+”)</script>”); }}如果写在页面端，则用户刷新一次，访问人数就增加voidSession_Start(object sender, EventArgs e){// Code that runs when a new session is started//在新会话启动时运行的代码//取出application中的值Application.Lock();int count = (int)Application["count"];count++;Application["count"] = count; //将此返回服务器Response.Write("你是第" + Application["count"] + "位访客");Application.UnLock();}将此写在Global.asax中使得页面只有通过重新访问，访问数才能增加，否则不能增加Lock()和UnLock()的意义是必须是一个加完后，另外一个在加Response的用法：Response用于向页面输出内容和实现页面的重定向Response.Write();Resposne.Redirect("网址")Response.Cookies.Add(); 用于添加CookieRequest的用法：Request用于获取表单的值String name=request.queryString["name"];String name=request.from["name"];String name=request.params["name"]; --最常用的一种方法String name=request["name"];Session的用法：(Session中可以传递各种数据类型的数据也可以传递类)Session用于在各个页面之间传递数据首先是将值存放在Session中：Session["name"] = name;Session["password"] = password;然后获取值：string name = (string)Session["name"];string password = (string)Session["password"];###在实际工作中，Session传递的值一般是一个封装类JavaScript中页面自动跳转的方法：将其添加在中即可实现中的自动跳转<SCRIPT LANGUAGE="JavaScript"><!--function redirect() { //跳转页window.location = "Default.aspx";}timer = setTimeout('redirect()', 5 * 1000); //跳转//--></SCRIPT>在中设置密码框即在TextBox中添加TextMode="password" ---利用中自身的TextBox设置密码框添加TextMode属性关于DropDownList的数据绑定：首先在DropDownList中的事件SelectedIndexChanged中添加：this.Image1.ImageUrl = "img/" + this.DropDownList1.SelectedValue.ToString();1、利用图形界面进行数据绑定，详见数据绑定视频2、利用ArrayList容器进行数据绑定，但是只能是5条一下的数据if (!IsPostBack){ArrayList list = new ArrayList();list.Add("1.jpg");list.Add("2.jpg");list.Add("3.jpg");this.DropDownList1.DataSource = list; //指定数据源this.DropDownList1.DataBind();}3、利用数据库操作进行动态的数据绑定（较为正规的用法）//利用数据库操作进行动态数据绑定if (!IsPostBack){stringstrConn = "server=LSC-BD9E16FDC63\\SQLEXPRESS;database=mldn;Uid=china;Pwd=1 2345678";SqlConnectionsqlConn = new SqlConnection(strConn);sqlConn.Open();SqlCommandcmd = new SqlCommand();mandText = "select * from Images";cmd.Connection =sqlConn;SqlDataAdaptersda = new SqlDataAdapter(cmd);DataTabledt = new DataTable();sda.Fill(dt);this.DropDownList1.DataSource = dt;this.DropDownList1.DataTextField = "imgs"; //添加显示给用户的数据this.DropDownList1.DataValueField = "imgs"; //添加传递给服务器的数据this.DropDownList1.DataBind();}在中利用onClientClick()事件调用JavaScript代码而不用onClick()事件在代码后面添加return false 阻止后面的代码执行在判断姓名文本框、密码框等不能为空的判断时，避免没有添加页面仍然跳转则在每一个判断后面添加一上return false,同时在onClientClick()中添加return javaScript方法CheckBoxList的用法：int count = this.CheckBoxList1.Items.Count;for (int index = 0; index <= count; index++){if (this.CheckBoxList1.Items[index].Selected){Response.Write(this.CheckBoxList1.Items[index].Text);}}RadioButtonList的用法：for (int index = 0; index < this.RadioButtonList1.Items.Count; index++){if (this.RadioButtonList1.Items[index].Selected){Response.Write(this.RadioButtonList1.Items[index].Text);}}Data中的Repeater的用法：主要用于分页首先拖动一个Reoeater控件，然后配置数据源在切换到代码视图，添加相应的模板，其中（）模板如下：<HeaderTemplate></HeaderTemplate><ItemTemplate></ItemTemplate> --必写<FooterTemplate></FooterTemplate><AlternatingTemplate></AlternatingTeplate> --隔行显示模板，实现隔行的显示方式对应实例：<form id="form1" runat="server"><div><asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"><HeaderTemplate><table border="1"><tr><td width="100">图片</td><td width="100">值</td></tr></table></HeaderTemplate><ItemTemplate><table border="1"><tr style=" color:Green"><td width="100"><%# Eval("imgs") %></td><td width="100"><%# Eval("imgsValue")%></td></tr></table></ItemTemplate><AlternatingItemTemplate><table border="1"><tr style=" color:Red"><td width="100"><%# Eval("imgs") %></td><td width="100"><%# Eval("imgsValue") %></td></tr></table></AlternatingItemTemplate><FooterTemplate><table border="1"><tr><td colspan="2">这是一个测试程序！！</td></tr></table></FooterTemplate></asp:Repeater><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:mldnConnectionString %>" SelectCommand="SELECT * FROM [Images]"></asp:SqlDataSource><br /><br /><br /><br /></div></form>ASP中的分页：真分页和假分页假分页：using System;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Web;usingSystem.Web.UI;usingSystem.Web.UI.WebControls;usingSystem.Data;usingSystem.Data.SqlClient;public partial class page : System.Web.UI.Page{privateintpageNumber = 0;privateintlineCount;public void pages(){stringstrConn = "server=LSC-BD9E16FDC63\\SQLEXPRESS;database=build;Pwd=12345678;Uid=china";SqlConnection conn = new SqlConnection(strConn);conn.Open();SqlCommandcmd = new SqlCommand();cmd.Connection = conn;mandText = "select * from fangyuan";SqlDataAdaptersda = new SqlDataAdapter(cmd);DataTabledt = new DataTable();sda.Fill(dt);PagedDataSourcepds = new PagedDataSource();pds.DataSource = dt.DefaultView;pds.AllowPaging = true;

//指定以何种字段为标准 ---关键this.DataList1.DataBind();conn.Close();删除方法：string bianhao = this.DataList1.DataKeys[e.Item.ItemIndex].ToString(); //用于获取对应的编号 ----关键stringstrConn ="server=LSC-BD9E16FDC63\\SQLEXPRESS;database=build;Pwd=12345678;Uid=china";SqlConnection conn = new SqlConnection(strConn);conn.Open();SqlCommandcmd = new SqlCommand();cmd.Connection = conn;mandText = "delete from fangyuan where bianhao='" + bianhao + "'";cmd.ExecuteNonQuery();conn.Close();每删除一次后对数据进行重新绑定，实现更新DXControls外部控件的使用：在使用DXControls时注册代码（放在<% @page 的下面）<%@ Register Assembly="DXControls" Namespace="DXControls" TagPrefix="cc1" %>在复制<cc1:dxtb id="concentdx" runat="server" height="100px" width="450px"></cc1:dxtb>该段代码到.aspx文件中在使用该控件时，必须在工程中导入Bin文件夹，同时该文件夹中必须存在DXControls.dll文件，还应导入dxtb文件夹，里面包含有相应的文件中验证控件的使用1、RequiredFieldValidator必填项验证，如网络上的*为必填项的实现必须对两个属性进行更改：ControlToValidate指定对哪个控件进行验证ErrorMessage当输入错误时显示的错误信息2、RegularExpressionValidator正则表达式验证，如对密码、邮箱等的验证必须对三个属性进行更改：ControlToValidate指定对哪个控件进行验证ErrorMessage当输入错误时显示的错误信息ValidationExpression写出对应的正则表达式3、RangeValidator数字界限验证，如3-100常见的正则表达式的匹配字符串：\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)* 为匹配邮箱地址防止用户未登录就访问页面的代码：<%If(Session(“name”) == null){Response.Redirect(“Login.aspx”);}%>通过Seesion在用户登录时存值，再每一个页面都判断是否存在Session传递的值，已判断用户是否登录，通常传递类Linq的使用：查询操作：//读取配置文件tStudentDataClassesDataContext context =new StudentDataClassesDataContext();//取出数据表中的所有内容System.Data.Linq.Table<student> list = context.GetTable<student>();//按照需求查询var query = from student in list select student;//或者语句的使用var query = from Person in context.Persons where Person.id == 1 || =="lsc" select Person;foreach(var student in query){Response.Write(+"<br />");}删除操作：（先查找再删除）PersonDataClassesDataContext context =new PersonDataClassesDataContext();System.Data.Linq.Table<Person> list = context.GetTable<Person>();var delete = from Person in context.Persons where Person.id==1 select Person; foreach (var Person in delete){//删除操作context.Persons.DeleteOnSubmit(Person);}context.SubmitChanges(); //提交操作Response.Write("删除成功");添加数据操作：PersonDataClassesDataContext context =new PersonDataClassesDataContext();System.Data.Linq.Table<Person> list = context.GetTable<Person>();Person p = new Person();p.id = 1; = "flq";p.password = "flq";context.Persons.InsertOnSubmit(p);//添加数据context.SubmitChanges(); //提交操作修改数据操作：PersonDataClassesDataContext context =new PersonDataClassesDataContext();System.Data.Linq.Table<Person> list = context.GetTable<Person>();var update = from Person in context.Persons where Person.id==4 select Person; foreach (var P in update){ = "wms";P.password = "wms";}context.SubmitChanges();利用Linq遍历数组：利用Linq对容器进行操作：如何利用Linq进行降序排列：以“c”结尾长度不大于5的人名。

ASP经典实用代码
1、数据库连接。
ASP与Access数据库连接：
<%@ language=VBscript%>
<%
dim conn,mdbfile powered by
mdbfile=server.mappath("数据库名称.mdb")
set conn=server.createobject("adodb.connection")
con.open "PROVIDER=SQLOLEDB;DATA SOURCE=SQL服务器名称或IP地址;UID=sa;PWD=数据库密码;DATABASE=数据库名称
%>
DW中用字符串连接代码：
"Driver={Microsoft Access Driver (*.mdb)};DBQ=数据库的绝对路径"
sql="SELECT * FROM data" '更改您的数据库表名
rs.Open sql,conn,1,1
6、获得系统的时间。
<%=now()%>
7、取得来访问的IP。
<%=request.serverVariables("remote_host")%>
8、随机数。
< % next % >
< /form >
12、常用SQL语句整理。
(1) 数据记录筛选：
sql="select * from 数据表 where 字段名=字段值 order by 字段名 [desc]"
sql="select * from 数据表 where 字段名 like ''%字段值%'' order by 字段名 [desc]"

第一节:注册系统（一），设定注册页面的外观：在这个例子中涉及了五个页面，其中有三幅是一般的htm文件，另外的两幅是asp文件，在这里制作利用的工具是frontpage98，但是大部分的asp代码还是要自己输入的：1，设定原来已经注册的用户进入的外观：在这里设置了两个文本框，一个超级链接和两个按钮。
两个文本框分别用来输入帐号（txtNum）和密码（txtPa sswd），超级链接（New）链接到新用户进行注册的页面，两个按钮是用来提交和清除的，用来清除的按钮（cmdReset）直接选择为Reset类型，不过用来提交的按钮（cmdTijiao）并不要选择为Submit类型，而选择的是Normal类型，这是为了在这个按钮的onClick事件中添加代码，并且判断用户的输入是否合法！2，设定新用户登陆的页面外观：一般都是要新用户输入帐号，密码，姓名，及相关的一些信息，在这里我们有五个文本框，一个下拉式列表框和两个按钮，五个文本框就分别是让用户输入姓名，email，帐号，密码，确定密码。
但是其中只有用来输入帐号，密码和确定密码的文本框有名字，分别为txtNum，txtPa sswd和txtConfirm。
提交按钮的名字为cmdTijiao3，这一步当然是设定注册成功后用户所进的页面了，这就由大家决定吧：）（二），添加程序代码：1，首先添加原来已经注册用户页面的代码，它主要是处理cmdTijiao_onClick事件，并且判断用户的输入是否合法，在这个例子中要求帐号必须是数字，密码不能为空，代码如下，其中frmRes是这个页面中窗口的名字，窗口的Action指向http://your/ResJudge.aspsub cmdTijiao_onClick()if frmRes.txtNum.value="" or frmRes.txtPasswd.value="" or (Not IsNumeric(frmRes.txtNum.value)) thenAlert"请在帐号和密码中输入相应的内容，帐号必须为数字！"else frmRes.submitend ifend sub2，添加新用户登陆的页面代码，这些代码是用来处理cmdTijiao_onClick事件的，要求用户输入的帐号必须是数字，密码和确定密码必须相同，这个页面的窗口的Action指向http://your/NewRes.asp，代码如下sub cmdTijiao_onClick()if Not Numeric(frmNew.txtNum.value) or frmNew.txtPasswd.value＜＞frmNew.txtConfirm.value thenAlert"输入不正确，请重新输入！"else frmNew.submitend ifend sub3，创建ResJudge.asp文件，这个asp文件的主要功能就是打开存储注册信息的数据库，查找是否有与前面页面提交的帐号和密码相匹配的纪录，如果有，就是注册成功，同时也可以在数据库中查找出这个用户的相关信息来，应允许这个用户进入他所希望进去的页面，如果没有则注册失败，整个代码如下＜html＞＜head＞＜meta http-equiv="Content-Type" content="text/html;charset=gb2312"＞＜meta name="GENERATOR" content="Microsoft Fronpage 3.0"＞＜titile＞注册判断＜/title＞＜/head＞＜body＞＜%Num=Request.form("txtNum") "把前面窗口传送来的内容赋给Num和Passwd两个字符串。

end if %＞＜/body＞＜/html＞4，创建 NewRes.asp文件，这个文件的主要功能是把新用户的登陆信息存入数据库，代码如下＜html＞＜head＞＜meta http-equiv="Content-Type" content="text/html;charset=gb2312"＞＜meta name="GENERATOR" content="Microsoft frontpage 3.0"＞＜title＞输入数据库＜/title＞＜/head＞＜body＞＜!--#Include virtual="/adovbs.inc"＞“这个被包含进来的文件adovbs.inc是定义数据库对象ADO常量的文件。

*文件名：book.htm＜html＞＜head＞＜title＞留言薄＜/title＞＜/head＞＜body bgcolor="#BED9FC" background="images/bg.gif"＞＜p align="center"＞＜img src="images/gbook.gif" alt="GBook.gif (12142 bytes)" WIDTH="374"HEIGHT="83"＞＜/p＞＜p align="center"＞[＜a href="disp.asp"＞我要看留言板＜/a＞] [＜a href="../index.asp"＞返回首页＜/a＞]＜/p＞＜form method="POST" action="book.asp"＞＜input type="hidden" name="task" value="insert"＞＜div align="left"＞＜table＞＜tr＞＜td align="right"＞姓名＜/td＞＜td＞＜img src="images/bottom-b.gif" alt="BUTTOM-B.GIF (179 bytes)" WIDTH="16" HEIGHT="16"＞＜/td＞＜td＞＜input name="name" size="46"＞＜/td＞＜/tr＞＜tr＞＜td align="right"＞性别＜/td＞＜td＞＜img src="images/bottom-g.gif" alt="BUTTOM-G.GIF (179 bytes)" WIDTH="16" HEIGHT="16"＞＜/td＞＜td＞＜input name="sex" size="46"＞＜/td＞＜/tr＞＜tr＞＜td align="right"＞来自＜/td＞＜td＞＜img src="images/bottom-b.gif" alt="BUTTOM-B.GIF (179 bytes)" WIDTH="16" HEIGHT="16"＞＜/td＞＜td＞＜input name="from" size="46"＞＜/td＞＜/tr＞＜tr＞＜td align="right"＞主页URL＜/td＞＜td＞＜img src="images/homepage.gif" alt="HomePage.gif (1232 bytes)" WIDTH="30" HEIGHT="30"＞＜/td＞＜td＞＜input name="url" size="46"＞＜/td＞＜/tr＞＜tr＞＜td align="right"＞E-mail＜/td＞＜td＞＜img src="images/email.gif" alt="Email.gif (1197 bytes)" WIDTH="30" HEIGHT="30"＞＜/td＞＜td＞＜input name="email" size="46"＞＜/td＞＜/tr＞＜tr＞＜td align="right"＞留言＜/td＞＜td colspan="2"＞＜textarea wrap="off" name="comments" cols="49" rows="9"＞＜/textarea＞＜/td＞＜/tr＞＜tr＞＜td＞＜/td＞＜td colspan="2"＞＜dl＞＜dd align="center"＞＜input type="submit" value="我写好了"＞＜input type="reset" value="重新再写"＞＜/dd＞＜/dl＞＜/td＞＜/tr＞＜/table＞＜/div＞＜/form＞＜p align="center"＞＜/p＞＜/body＞＜/html＞您可以按这里看一下这个界面的效果（需要强调一点，这些htmL代码还是完全没有功能的）你可以把它保存为book.htm，然后用FRONTPAGE98来打开它，打开后，可以查看网页中的那个输入FORM的属性，在这个留言薄中。
