what might be best suited to place in the Application_Start and Session_Start subroutines? I know when each subroutine is called. Application_Start when the first user first accesses the web application. Session_Start when a user opens a session with the application. But what code belongs in each of these subroutines. What should the code in each subroutine do?

i wrote some code in application start event in global.asax page...
how to call that event in my every .cs page of my project.
I have a custom provider for authenticaiton that is HTTP Module-based. IIS authentication and web.config authentication is configure to 'None' and allow anonymous. When I probe for User.Identity.Name in Session_Start, it is empty. However User.Identity.Name works elswhere in the application as expected (returns the current user id). Is it possibly during Session_Start no authentication request has been issued, therefore there is no principal at this moment?
View 1 RepliesI have a simple aspx Page, which html contains:
[Code]....
and code behind:
[Code]....
This is quite simple. When I press btn1, it sets correctly the Session Key. And this is then the issue arrives: When I press one of these buttons, this is the sequence of what happens:
Global.asax: Session_Start
MyPage.aspx: Page_Load » btnX_Click
So, everytime there is a PostBack, even before the Page loads, the session starts and generates a new Id. This way, I loose everything during the PostBack. My Session State configuration:

This is running on VS 2010 + V3.5, on IIS5.1. The Page header configuration is default.
In my company app they are doing the following. I do not understand that what initialize does? Do we need to Initialize assemblies before using them? and what kind of assemblies needs to be initialized?

When I am debugging an application in ASP.NET, after about ~5 minutes I get a NullRefEx coming from global.asax.cs regarding:
protected void Session_Start(Object sender, EventArgs e)
{
WindowsIdentity identity = null;
identity = (WindowsIdentity)(Context.User.Identity);
...
Context is Null at this point. I am a noob in ASP.NET with regards to Global.asax.cs. This code was written by another developer. EDIT: This is the code with HttpContext...
protected void Session_Start(Object sender, EventArgs e)
{
WindowsIdentity identity = null;
identity = (WindowsIdentity)(HttpContext.Current.User.Identity);
Suppose my website address is like http://localhost/MyWebsite
I wanted to access this url in Application_start event in global.asax, Can i some how get it?
[I know i can get it via application_beginrequest or other event]
I'm trying to use SESSION in my MVC application.I wrote following line in Global.asax in Application_Start() method file:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
//uzupełnij zmienne sesyjne
HttpContext.Current.Session["LOCATION_ID"] = 15;
RegisterRoutes(RouteTable.Routes);
}
I also enabled SessionState in Web.config by addind following line:
<sessionState mode="InProc" cookieless="false" timeout="120" />
And when I run the application I'm getting this exception:
Szczegły wyjątku: System.NullReferenceException: Odwołanie do obiektu nie zostało ustawione na wystąpienie obiektu.
Błąd źrdła:

I have the same issue, I have added the On before the Application start, or Session Start and it is still not working.Application_OnStart or Application_Start is not firingSession_OnStart or Session_Start is not firing..Note that in my development environment it is firing (both of the names).When I am adding the Global.asax file, there is only one file (no .cs file). And when I am publishing the project, I am not getting the Global.asax file, I am getting a xxxxGlobal.asax.dll file on my bin folder...
View 1 RepliesI have recently published my website, it worked fine but the only issue is that the error handling code in the global.asax never works. It works when I tested the website on my localhost but not when it is deployed onto my hosting provider.
I tried moving my global.asax file onto my root directory (not the bin) on the hosting folder, then my whole website wouldn't even start. I get the error message "System.Web.HttpException: This server variable cannot be modified during request execution."
But if I remove the global.asax, then it is running fine again.
Note: I didn't use the publish function in Visual Studio to publish my website, I sent the files over one by one via cPanel. Note: I googled about this, a lot of them are saying about global.asax being precompiled into a dll, but I can't find that dll in my local computer.
Currently using asp.mvc in application. there is problem related to my URL. I have changed Routing respectively as per the mvc pattern URL. In Global.asax Code :
routes.MapRoute("Default",
// Route name
"{controller}/{action}/{ID}/{PRODUCT}/{CATEGORY}",
// URL with parameters
new { controller =
"Home", action = "LogOn", ID =
UrlParameter.Optional, PRODUCT =
UrlParameter.Optional, CATEGORY =
UrlParameter.Optional}
// Parameter defaults );
In Grid, While click row of ProductDetails link URL will be : [url] When click on same thik i click on product Page link i am calling method "ProductDetails". Expected URL would be [url]
I have a Global.Asax and Global.Asax.cs file that is specific to my particular Asp.net project. For some unknown reason the code in my Global.asax.cs file is not being executed. I thought that the breakpoints were being ignored, however that is not the case. Because if I try to deliberately force an error to occur, the code is never executed. Below is an example of what I am talking about. The real code in my Application_Start method is not shown below. ANd other methods are not shown as well.
I have tried renaming the Global.asax file and then re-creating it, and that did not work either. Strange because when I try and create a new Global.asax file, the option to create a code behind file is greyed out.
Why isn't my Global.Asax.cs code being executed?
private void Application_Start(object sender, EventArgs e)
{
int x = 1;
int y = 1;
int z=1/(x-y)
}
migrating my ASP.NET project from IIS 6 to IIS 7.5 I came across an issue with the Managed Pipeline Mode set to 'Integrated'.I have a Global.asax file in my web root to initialize some objects, gather data etc., however I am not able to hit breakpoints in the associated code-behind file (VS 2008). The code is executing very well (as I can tell from Eventlog), but I want to step into all that initializing there and need to have the debugger attached properly.Everything is working as expected in Classic pipeline mode. Since I'd like to benefit from Integrated Mode features in the future I wonder if I have to give up the ability to debug my Application start and error events...
View 1 RepliesI'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;
I am using Visual Studio 2005, and running my application from inside it, directly using its development application server.
If I set a breakpoint inside Application_Start and one inside Session_Start, the latter is reached first, and I honestly think it should be the other way around.
I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.
I have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?

View 4 RepliesIs it possible in the global.asax file on session_start to check if a url string exists and it it does insert the string into a sql database? The url would be something link http://www.mysite.com?campaign=january.
I would want to capture the january bit and put that in the database for each visitor that uses that url.
I am using form authentication in my website. I have a scenario wherein the user is authenticated but the session has timed out. So, i would like to initialize some session variables in Session_Start of Global.asax (First i check if Request.IsAuthenticated=True). For that i required the name of the user who authenticated. On .aspx pages we can get it using Page.User.Identity.Name but how to get it in global.asax page.

how can i use it ?
I have a hosting account on DailyRazor.com , i use Global.asax in my project to start a schedule process in Application_Start.When i just publish my website, and upload it, the Application_Start does not Fire, but when i upload the Global.asax to my host it gives an Error but the Applicaiton_Start Event fires up, and then i delete the Global.asax file and everything works.just wondering, What am doing wrong ? or why this meaningless thing happens?
View 2 RepliesI have a site with multiple domains pointing to it. I wanted to redirect all requests to main domain so I've created a method called RedirectToRealDomain("domain.com") to check and redirect all requests to my preferred domainAt the moment it lives on Session_Start but I am planing to move it to Application_BeginRequest event. As I understand Session_Start only raised when new session started but Application_BeginRequest raised on all requests. RedirectToRealDomain method doesn't do any DB lookups or anything expensive apart from comparing strings.
