msgBox in ASP.NET

[suganya]

Hi

I have created the class "WebMsgBox. cs" in App_Code. The coding is

using System;

using Microsoft.VisualBasic;

using System.Text;

using System.Collections;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

    public class WebMsgBox
    {

        protected static Hashtable handlerPages = new Hashtable();

        private WebMsgBox()
        {

        }



        public static void Show(string Message)
        {

            if (!(handlerPages.Contains(HttpContext.Current.Handler)))
            {

                Page currentPage = (Page)HttpContext.Current.Handler;

                if (!((currentPage == null)))
                {

                    Queue messageQueue = new Queue();

                    messageQueue.Enqueue(Message);

                    handlerPages.Add(HttpContext.Current.Handler, messageQueue);

                    currentPage.Unload += new EventHandler(CurrentPageUnload);

                }

            }

            else
            {

                Queue queue = ((Queue)(handlerPages[HttpContext.Current.Handler]));

                queue.Enqueue(Message);

            }

        }



        private static void CurrentPageUnload(object sender, EventArgs e)
        {

            Queue queue = ((Queue)(handlerPages[HttpContext.Current.Handler]));

            if (queue != null)
            {

                StringBuilder builder = new StringBuilder();

                int iMsgCount = queue.Count;

                builder.Append("<script language='javascript'>");

                string sMsg;

                while ((iMsgCount > 0))
                {

                    iMsgCount = iMsgCount - 1;

                    sMsg = System.Convert.ToString(queue.Dequeue());

                    sMsg = sMsg.Replace("\"", "'");

                    builder.Append("alert( \"" + sMsg + "\" );");

                }

                builder.Append("</script>");

                handlerPages.Remove(HttpContext.Current.Handler);

                HttpContext.Current.Response.Write(builder.ToString());

            }

        }

    }

In code behind I called the msg box by

WebMsgBox.Show( "select any of the above");


But msgbox is not getting displayed when I run the project.
