Function in Global.asax is not running

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :ASP.Net
Hi, I am using a Global.asax in on my webpage to run a function with an interval. In this test I have set the interval to 1 minute to be able to see what happens. I have declared a timer in the Application Start which should mean that when I open up the webpage after I have uploaded the Global.asax the timer will start.   However with this code below where I try to create a file named newFile.txt, this file is not created. I cant really understand what I could be missing. It seems that the function is not running ?<%@ Application Language="C#" %> <%@ Import Namespace="System" %> <%@ Import Namespace="System.Collections.Generic" %> <%@ Import Namespace="System.Linq" %> <%@ Import Namespace="System.Web" %> <%@ Import Namespace="System.Web.UI" %> <%@ Import Namespace="System.Web.UI.WebControls" %> <%@ Import Namespace="System.Drawing" %> <%@ Import Namespace="System.Net.Mail" %> <%@ Import Namespace="System.Net" %> <%@ Import Namespace="System.Threading" %> <%@ Import Namespace="System.IO" %> <%@ Import Namespace="System.Text" %> <%@ Import Namespace="Microsoft.Win32" %> <%@ Import Namespace="System.Reflection" %> <%@ Impo

Windows 7, IIS 7.5 and VS2010: can't edit global.asax


Hey and thanks!


As the subject line notes the software in use, anyone have an idea why I can't edit global.asax in VS2010 (being ran with the 'run as administrator' advanced property check box checked)?  The file properties in explorer show local machine admins have full control (I am in that category) and also that IIS has windows auth enabled for the default web site.  What is this other level of security on here that I'm missing?  I can edit web.config, vb files and general aspx files with no problem--just the global.asax file causing a headache...





SSRS 2005 SP3 - Instr function with Global Variable fails in Subscriptions

Hi I have a very simple expression in a text box in my report:  INSTR(Globals!ReportServerUrl,"Report").  This expression should return the integer value of where the string "Report" appears in the Global variable for the ReportServerUrl.  Simple enough.  This works fine for generating the report directly through report manager, and in my case returns a value of 20. However when run as a subscription and emailed to myself the value returned is 0. This suggests that the search string does not appear in the Global variable. In the reportserver config file the URLroot tag contains the correct server address - http://myserver/reportserver. Does anyone know why i should be experiencing this issue with my subscriptions?  Your help would be much appreciated! Thanks Guy  Guy

Using Global.asax to Set Session Variables Pulled From SQLServer

I have a custom class that pulls user information from a SQL Server table. Now that I'm expanding the site from a single page to others. I want to shift the code to the Session_Start event so that the information is always loaded when the site is accessed. How do I call my custom code from global.asax since its script and not a class. 

Global.asax Application_BeginRequest

When I was in the link page is a link to the site all the program, Application_BeginRequest event in Global.asax is triggered, But my link is a link to an external time will not trigger this event, and I ask when my link is connected to an external URL, How to trigger Application_BeginRequest event Thank you.   Such as web link in the URL if connected to yahoo, I take it lead to another page.  Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs) Dim originalPath As String = HttpContext.Current.Request.Url.Host.ToLower() If originalPath.Contains("yahoo") Then Context.Response.Redirect("StopUrl.aspx") End If End Sub  

Application level event without global.asax

I have a need to add an application level event (like Application_Start) but not in global.asax.  The reason that I can't use global.asax is because this is a web application for which I don't have source code but I want to add some functionality to it.  I need to insert an application start code and was wondering it there was anyway to do it.  I'm not sure that if I add a class or aspx page to the sie if it will dynamically compile since this is a web application.  I know this is a crazy request but let me know what you think.Also, this web site was written in .NET 2.0.Thanks.

Passing data to a Controller from global.asax


Hello all! I'm in a situation where I need to pass some information (state) to a base controller from which all of my controllers derive. In my global.asax, I'm calling a web service to get some state about the user. This state applies to every page in my web app, so the base controller needs to know about it. The state consists of about 4 fields. Is there a standard way to do this?

Empty Catch in Global.asax to prevent exception from stopping a web application?



I'm using a static Timer in my Global.asax to run a method at regular intervals. When the method throws an exception, my application is stopped. I have used an empty catch to prevent exceptions from stopping the application something like below code. Is there a disadvantage to use such an approach?


 protected void Application_Start(object sender, EventArgs e)

 public class TimerStarter
            private static System.Threading.Timer threadingTimer;

            public static void StartTimer()
                if (null == threadingTimer)
                    threadingTimer = new System.Threading.Timer(new System.Threading.TimerCallback(CheckData),HttpContext.Current, 0, 50000);

            private static void CheckData(object sender)
                   // a method that reading xml file from another url              
                    // empty catch to prevent stopping the application




Session end and global.asax



I'm wondering if ther's a simple way of achieving the following.

When a new session starts, I create some cookies and session objects from global.asax session start.

If a user logs out, I want to abandon the session - I presume using session.abandon, and i also want to clear the cookies.  They are set to expire after the session ends (no expiry date).  This may be an automatic thing, but I've not tested as yet.

When a user logs back in again I want to recreate those objects - in other words, kick off global.asax again.  Is that what happens or do I need to recreate manually?



Exception handling in Global.asax of ASP.net


I want to handle exceptions in my applications in Global.asax and transfer the exception to my custom error page, so that is in a central place. I want to take this exception object into my oopserror.aspx page and format it and display a custom message. i tried to use GetLastError() in my oopsError.aspx page, but my exception object was always null. Following is the code snippet that i'm using and i'm getting exception.

void Application_Error(object sender, EventArgs e)
   // Code that runs when an unhandled error occurs
   Exception exception;
   exception = Server.GetLastError();

   Session.Add("Exception", exception);


Following is the exception when the above code is executed.

{"Session state is not available in this context."}
   at System.Web.HttpApplication.get_Session()
   at UserInterface.Global.Application_Error(Object sender, EventArgs e) in C:\UserInterface\Global.asax.cs:line 51
   at System.EventHandler.Invoke(Object sender, EventArgs e)
   at System.Web.HttpApplication.RaiseOnError()

Is there a way that i can securly take my session object from global.asax to my oopserror.aspx? Any ideas?

Global.asax file in WCF for different end points


Global.asax is available in asp.net application. But when I added WCF application i couldn’t find the file. I saw read in one of the questions that global.asax cannot be used for tcp endpoints.

I’m trying to use application_error method in global.asax and catch all the exceptions in this method.


How can I use global.asax with http and tcp endpoint? Or is there any other way to implement this?


PostBack triggers Session_Start on Global.asax


Hi all, I'm facing a strange issue.

I have a simple aspx Page, which html contains:

<asp:Button ID="btn1" runat="server" Text="Set Session" onclick="btn1_Click" /> 
<asp:Button ID="btn2" runat="server" Text="Get Session" onclick="btn2_Click" />

and code behind:

public partial class MyPage : System.Web.UI.UserControl
    private List<string> myElements
        get { return (List<string>)Session["elements"]; }
        set { Session["elements"] = value; }

    protected void Page_Load(object sender, EventArgs e)


    protected void btn1_Click(object sender, EventArgs e)
        List<string> strs = new List<string>();

        myElements = strs;

    protected void btn2_Click(object sender, EventArgs e)
        List<string> strs = myElements;

        if (strs != null && strs.Count > 0)
            string s = "Ok";


This is quite simple. When I press btn1, it sets correctly the Session Key

Redundant SQL code to "set up" my code behind. Can I put it in the global.asax?


I've moved away from using sqldatasources, and now I exeucte all my sql in my code behind.   However, I'm looking to make my codebehind a little more cleaner/neater.  For example, on one page, there are three stored procedures that must execute, and All three have these same 8 lines of code for each of my three stored procedures.   How can I condense my code behind to not always have to add this...

        SqlConnection conn = default(SqlConnection);
        SqlCommand comm = default(SqlCommand);
        SqlDataReader reader = default(SqlDataReader);
        string connectionString = ConfigurationManager.ConnectionStrings["xyz"].ConnectionString;
        conn = new SqlConnection(connectionString);
        comm = new SqlCommand();
        comm.Connection = conn;
        comm.CommandType = System.Data.CommandType.StoredProcedure;
