  • Asp.NET生成静态页面并分页

    因为公司的产品用asp开发， 前一段时间用asp写了一个生成静态页面并分页的程序，但缘于对.net的热爱，写了这个.net下的生成静态页面并分页的程序。

    主要的原理就是替换模板里的特殊字符。

    1、静态模板页面 template.html，主要是定义了一些特殊字符，用来被替换。

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <title>Title </title>
    </head>
    <body>
    <div style="width: 417px; height: 54px" align="center">
    <br />
    Title </div>
    <div style="width: 417px; height: 8px">
    浏览 <font color="red"> <script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=NewsId"> </script> </font>次 Time </div>
    <div style="width: 417px; height: 100px">
    Content </div>
    <div style="width: 416px; height: 9px">
    Pager </div>
    <div style="width: 416px; height: 8px">
    <form id="form1" action="../AddComment.aspx" style="margin:0px">
    <input id="Text1" type="text" /> <Img id="Image1" src="http://www.dwww.cn/UserInfo/CheckCode.aspx"/> <br />
    <textarea id="CommentContent" cols="20" rows="2"> </textarea>
    <br />
    <input id="NewsId" type="hidden" value="NewsId"/>
    <input id="Button1" type="submit" value="button" />
    <a href="http://www.dwww.cn/News/Display.aspx?NewsId=NewsId">查看更多评论 </a> </form>
    </div>
    </body>
    </html>


    2、前态页面 NewsAdd.aspx，就是一个表单，用来填写新闻的标题和内容。

    <%@ Page Language="C#" AutoEventWireup="false" validateRequest="false" CodeFile="NewsAdd.aspx.cs" Inherits="NewsAdd.Admin_AdminPanel_NewsAdd" %>
    <%@ Register TagPrefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2" Assembly="FredCK.FCKeditorV2" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
    <title>添加新闻 </title>
    </head>
    <body>
    <form id="form1" runat="server">
    <div>
    <asp:Label ID="Label2" runat="server" Text="标题"> </asp:Label>
    <asp:TextBox ID="Title" runat="server" Width="325px"> </asp:TextBox> <br />
    <asp:Label ID="Label1" runat="server" Text="内容"> </asp:Label>
    <FCKeditorV2:FCKeditor id="Content" basePath="~/FCKeditor/" runat="server" Height="400px" Width="70%"> </FCKeditorV2:FCKeditor>
    <asp:Button ID="Button1" runat="server" onClick="Button1_Click" Text="Button" />
    <asp:Label ID="Message" runat="server" > </asp:Label> </div>
    </form>
    </body>
    </html>


    3、后台页面 NewsAdd.aspx.cs

    using System;
    using System.Data;
    using System.Configuration;
    using System.Collections;
    using System.Web;
    using System.Web.Security;
    using System.Web.UI;
    using System.Web.UI.WebControls;
    using System.Web.UI.WebControls.WebParts;
    using System.Web.UI.HtmlControls;
    using Mysqlserver;
    using System.IO;
    using System.Text;
    namespace NewsAdd
    {
    public partial class Admin_AdminPanel_NewsAdd : System.Web.UI.Page
    {
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
    string strDate = DateTime.Now.ToString("yyMMdd") + "\" + DateTime.Now.ToString("yyyymmddhhmmss");
    string strFileName = strDate + ".shtml";//存储到数据库中
    string strTitle=Request.Form["Title"].ToString().Trim();//接收传过来的标题
    string strContent=Request.Form["Content"].ToString().Trim();//接收传过来的内容
    string[] content = strContent.Split(new Char[] {' ¦'});//对内容进行拆分，并保存到数组
    int upbound = content.Length;//数组的上限
    SqlServerDataBase db = new SqlServerDataBase();
    bool success = db.Insert("insert into inNews(Title,Content,FilePath)values('" + strTitle + "','" + strContent + "','" + strFileName + "')", null);
    //if (success)
    // Message.Text = "添加成功！";
    /**////////////////////////////创建当前日期的文件夹开始
    string dir = Server.MapPath("../../"+"NewsFiles/"+DateTime.Now.ToString("yyMMdd"));//用来生成文件夹
    if (!Directory.Exists(dir))
    {
    Directory.CreateDirectory(dir);
    }
    /**////////////////////////////创建当前日期的文件夹结束
    try
    {
    for (int i = 0; i < content.Length; i++)
    {
    //string[] newContent = new string[4];//定义和html标记数目一致的数组
    StringBuilder strhtml = new StringBuilder();

    //创建StreamReader对象
    using (StreamReader sr = new StreamReader(Server.MapPath("../../" + "NewsFiles/") + "\template.html",Encoding.GetEncoding("gb2312")))
    {
    String oneline;
    //读取指定的HTML文件模板
    while ((oneline = sr.ReadLine()) != null)
    {
    strhtml.Append(oneline);
    }
    sr.Close();
    }

    //为标记数组赋值
    //SqlServerDataBase db = new SqlServerDataBase();
    DataSet ds = db.Select("select top 1 NewsId from inNews order by NewsId desc", null);//获取id
    string strTable = " <table> <tr> <td>upUrl </td> <td>Number </td> <td>downUrl </td> </tr> </table>";//上下页表格，注意此处的upUrl（上一页），Number（页码分页），downUrl（下一页）
    //这三个是用来替换的。

    string FilePath="";
    strhtml = strhtml.Replace("Title", strTitle);
    strhtml = strhtml.Replace("NewsId", ds.Tables[0].Rows[0]["NewsId"].ToString());
    strhtml = strhtml.Replace("Time", DateTime.Now.ToString("yyyy/MM/dd"));
    strhtml = strhtml.Replace("Content", contentIdea);
    string strNumber = "";//数字分页1，2，3……
    for (int m = 1; m <=upbound; m++)
    {
    if (m == 1)//如果是第一页就显示成这个样子：20070524.shtml而不是20070524_1.shtml
    strNumber = strNumber + " ["+" <a href=" + "../" + strDate + ".shtml" + ">" + m + " </a>"+"] ";
    else
    {
    int n = m - 1;//第三页的连接应该是20070524_2.shtml，以此类推
    strNumber = strNumber + " [" +" <a href=" + "../" + strDate + "_" + n + ".shtml" + ">" + m + " </a>"+"] ";
    }
    }
    if (upbound == 0)//如果没有分页，就直接按日期时间保存
    {
    FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + ".shtml";
    strhtml = strhtml.Replace("Pager", "");
    }
    else//否则按20070524.shtml、20070524_1.shtml 这种效果保存
    {
    if (i == 0)
    FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + ".shtml";
    else
    FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + "_" + i + ".shtml";

    if (i == 0)//第一页不显示上一页
    strTable = strTable.Replace("upUrl", "");

    if (i <= 1)//上一页分页
    strTable = strTable.Replace("upUrl", " <a href=" + "../" + strDate + ".shtml" + ">上一页 </a>");
    else
    {
    int p = i - 1;
    strTable = strTable.Replace("upUrl", " <a href=" + "../" + strDate + "_" + p + ".shtml" + ">上一页 </a>");
    }

    if(upbound==1)//如果只有一页，则不显示页码
    //strNumber="";
    strTable = strTable.Replace("Number", "");
    else
    strTable = strTable.Replace("Number", strNumber);//页码替换
    /**/////////////////////////
    if(i==upbound-1)//最后一页不显示下一页
    strTable = strTable.Replace("downUrl", "");

    if (i != upbound - 1)//下一页分页
    {
    int q = i + 1;
    strTable = strTable.Replace("downUrl", " <a href=" + "../" + strDate + "_" + q + ".shtml" + ">下一页 </a>");
    }
    else
    {
    int j = upbound - 1;
    strTable = strTable.Replace("downUrl", " <a href=" + "../" + strDate + "_" + j + ".shtml" + ">下一页 </a>");
    }

    strhtml = strhtml.Replace("Pager", strTable);
    }
    //创建文件信息对象--------------------------------------------
    FileInfo finfo = new FileInfo(FilePath);
    //以打开或者写入的形式创建文件流
    using (FileStream fs = finfo.OpenWrite())
    {
    //根据上面创建的文件流创建写数据流
    StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.Default);
    //把新的内容写到创建的HTML页面中
    sw.WriteLine(strhtml);
    sw.Flush();
    sw.Close();
    }
    }
    }
    catch (Exception err)
    {
    //输出异常信息
    Response.Write(err.ToString());
    }
    }
    }
    }


    请不要直接拷贝使用，里面的路径需要更改，但程序绝对没问题，在我本地已经测试通过。

    另外在使用时，比如我要把新闻的内容分成4页，就应该这样写：111 ¦222 ¦333 ¦444。

  • 再遇ORA-12516

    記得以前有過一次，今天用戶再次反應又連不上數據庫了，遇到問題總要先查找原因，後尋找解決辦法，這個過程困難，也給心裡造成壓力。

    避免後續再次出現同樣的問題，能夠最快時間順利輕鬆解決，今天就記錄之，平衡心理壓力呵...

    問題描述：

    [oracle@test dbs]$ oerr ora 12516
    12516, 00000, "TNS:listener could not find available handler with matching protocol stack"
    // *Cause: None of the known and available service handlers for the given
    // SERVICE_NAME support the client's protocol stack: transport, session,
    // and presentation protocols.
    // *Action: Check to make sure that the service handlers (e.g. dispatchers)
    // for the given SERVICE_NAME are registered with the listener, are accepting
    // connections, and that they are properly configured to support the desired
    // protocols.

    而spfile文件中processes = 150,從而判斷，這個值太小導致新用戶無法再連入DB.

    數據庫處於not log on 狀態，無法直接修改相應參數，於是就先把相關oracle進程kill掉後，可以正常登錄數據庫.
