Ovako:
1. Napravi user kontrolu, nazovije je, na primer, WucCounter
2. U code behind copy/past ovo što sam naveo pod WucCounter.cs
3. U aspx file copy/paste ovo što sam naveo pod WucCounter.aspx
4. CSS u aspx (CssClass="cntnumber") podesi po nahođenju
5. Ovo log.Error("xxx", ex); je od log4net open source projekta - za početak stavi pod komentar

To bi bilo to.

WucCounter.cs:

Code:

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 System.IO;

public partial class UserControls_WucCounter : System.Web.UI.UserControl {
    protected static readonly log4net.ILog log =
        log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

   protected void Page_Load(object sender, EventArgs e) {
        if (!IsPostBack) {
            DoCount();
        }
   }

    protected void DoCount() {
        HttpCookie cookie = Request.Cookies[COOKIE_NAME];
        GetCounter();

        if (cookie == null) {
            cookie = new HttpCookie( COOKIE_NAME, DateTime.Now.ToString());
            cookie.Expires = DateTime.Now.AddHours(1);
            IncCounter();
        } else {
        }
        vCnt.Text = cnt.ToString("0000000");
        Response.Cookies.Add(cookie);
    }

    protected int cnt = 1;

    protected const string COOKIE_NAME = "LastVisit";
    protected const string RELATIVE_FILE_NAME = "App_Data/counter.txt";

    protected string FileName { get { return Server.MapPath(RELATIVE_FILE_NAME); } }

    protected void GetCounter() {
        try {
            StreamReader sr = new StreamReader(File.Open(FileName, FileMode.OpenOrCreate));
            string sCnt = sr.ReadLine();
            sr.Close();
            cnt = sCnt != null ? int.Parse(sCnt) : cnt;
        } catch (Exception ex) {
            log.Error("GetCounter", ex);
        }
    }

    protected void IncCounter() {
        cnt++;
        try {
            StreamWriter sw = new StreamWriter( File.OpenWrite( FileName ) );
            sw.WriteLine(cnt.ToString());
            sw.Close();
        } catch (Exception ex) {
            log.Error("IncCounter", ex);
        }
    }
}

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -Brian Kernighan
