笨人笨方法

Tue, 06 Jan 2009 12:23:35 +0000

后台验证是否非法登陆，就是直接输入url登陆拒绝

    protected void Page_Load(object sender, EventArgs e)
    {
           if (Session["adminusername"] != null)
        {
        }
        else
        {
            Response.Redirect("../Default.aspx");
        }
    }

终于搞定历史流量的统计，老规矩，共享起

我是把它作为一个自定义控件放在网页里，可以自己发挥

上面是网页的结构图，下面说的是控件的，所以仅供参考

上面是效果图

下面代码，注意是自定义控件

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="tingjiqi.ascx.cs" Inherits="tingjiqi" %>

                    counterData.WriteXml(dataOut, XmlWriteMode.WriteSchema);

                }
                countMsg.Text += counterData.Tables[0].Rows.Count.ToString();

            }
            catch (Exception edd)
            {
                //收集其他信息
                Response.Write("An Exception Occurred " + edd.ToString() + "");
            }

        }
    }
}

使用调用这个控件就行了，数据储存在App_Data/xmlcounter.xml里

网站流量（历史流量统计）

Thu, 18 Dec 2008 14:22:23 +0000

就是当有人打开网页先从数据库读取以前存的数据，然后加一，然后在他离开时存回数据库，实现网站流量（历史流量）的统计，希望使用VS2005，C#+ACSSEE编的源码，跪求啊，头都想破了~~

ASP.NET统计在线人数

Thu, 18 Dec 2008 05:38:56 +0000

利用Application对象和Session对象可以统计当前在线用户数量。

　　（1）Application对象是HttpApplication类的实例。它可以在多个请求、连接之间共享公用信息，也可以在各个请求连接之间充当信息传递的管道。此对象的生命周期起始于IIS开始运行并且有人开始连接时，终止于IIS关闭或者若干时间内无人连接时。当Application对象的生命周期开始时，Application_Start事件会被启动，当Application对象的生命结束时，Application_End事件会被启动。本实例中，当应用程序启动时，在Application_Start事件下初始化计数器。其代码如下。

//在应用程序启动时运行的代码
//初始化
Application["counter"]=0;

（2）Session对象是System.Web.UI.HttpSessionState类的实例。Session对象的所有引用都是在引用当前用户的会话对象，这个对象提供了字典风格的访问机制，当特定的用户不再访问Web站点上的页面时，一些信息将被丢掉。在新会话启动时，使计数器自增。关键代码如下。

//在应用程序启动时运行的代码
//初始化
//在新会话启动时运行的代码
//对Application加锁以防并行性
Application.Lock();
//增加一个在线人数
Application["counter"]=(int)Application["counter"]+1;
Application.UnLock();　　//解锁

　　在会话结束时，使计数器自减。关键代码如下。

Application.Lock();
//减少一个在线人数
Application["counter"]=(int)Application["counter"]-1;
Application.UnLock();　　　　//解锁

在主页Default.aspx第一次加载时，将Application[“counter”]赋给Label.text，实现在界面上显示在线人数，其代码如下。

Label1.Text=Application["counter"].ToString();

JS显示动态的时钟,显示完整的一些方法,新年倒计时

Wed, 17 Dec 2008 14:30:28 +0000

JS显示动态的时钟,显示完整的一些方法,新年倒计时，慢慢研究中

<%@LANGUAGE="JAVASCRIPT" CODEPAGE="936"%>

js核心对象之Date

时间对象作为非常重要的一个对象，对我们学.net的人来说，并不是很重要，但这并不意味着我们可以忽略，事实上，用得着的时候还是很多的，如果完全依赖JS处理时间，那是会出问题的，因为JS总是假设本地机器上的时间是正确的。还有个原因，他总按照GTM市区来计量。我们只是返回当前date对象的副本，我们即便是修改，那也不会对对象本身有任何影响。

演示一：动态的时钟（来个复杂的）

演示二：显示完整的一些方法（事实上我很讨厌有些格式了）

演示三: 倒计时

隐藏字段控件HiddenField

Wed, 17 Dec 2008 14:21:48 +0000

页面代码

后台代码

附上：可以使用HiddenField来实现记录当前时间的控件，具体如下：
前台放置FiddenField

后台代码Page_Load事件中

    protected void Page_Load(object sender, EventArgs e)
    {
        hdtime.Value = DateTime.Now.ToString();
    }

要使用时在你的InsertQuery中如下图

        {
           FileUpload1.SaveAs(Server.MapPath("up")+"\\"+fullname);//将文件保存在根目录的UP文件夹下

        else
        {
            Label1.Text = "文件格式不正确";

朋友

Sat, 13 Dec 2008 03:15:39 +0000

什么是朋友，很难定义，但绝对不是在你有难或错误时跟别人一起给你最后一脚的那种。如果有这样的朋友，还是不要为妙。

面对朋友，即使自己自尊心越强，也要适当的学会妥协，如果一次妥协的不给，以为自己永远正确，那这种朋友不要也罢。
