Just for kicks, how do you say, wire up an ASP button to purposely throw an Application_Error exception in the global.asax file?
lets say you wanted to test the functionality of the error handling and what is doing..and you don't have a real error to do it. what is the easiest way just raise this event?
I'm trying to handle all my application exceptions inside the global.asax but from some reason it's not firing at all, i never tried to do it before so i guess i'm doing something wrong here...
here is the code inside the default.aspx page that throw the error:
[Code]....
Looking for best practice focused answers here with explanations.
Should the presentation layer of an ASP.Net app catch and handle exceptions thrown from the business layer, or should these be allowed to bubble out, where they can all be logged and handled uniformly in the Global.ascx's Application_Error handler?
[code]....
I am handling errors in Global.asax. When I encounter an error in certain pages, the Application_Error event fires twice. On the second trip, Server.GetLastError() returns null. I have a simple page where I throw an error in page load. When that page throws an error the code below works fine. I also have a more complex page with an update panel and many controls. When that page throws an error Application_Error fires twice. I suspect the update panel but update panels are always suspect, right?
There are no try/catch blocks on any of my pages I'm testing with. Custom errors in web.config is commented out. Note that logging and busywork in the Application_Error event are commented out. I'm pretty much just doing a respone.redirect. The problem with the the event firing twice is that the response.redirect fails with an error msg stating that headers have already been sent (adding Context.ClearError and Response.Clear does nothing to fix that).
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.
Whenever an unhandled exception occurs on our site, I want to:
Send a notification email Clear the user's session Send the user to a error page ("Sorry, a problem occurred...")
The first and last I've had working for a long time but the second is causing me some issues. My Global.asax.vb includes:
[Code]....
When I run a debug, I can see the session being cleared, but then on the next page the session is back again!
I eventually found a reference that suggests that changes to session will not be saved unless Server.ClearError is called. Unfortunately, if I add this (just below the line that sets "ex") then the CustomErrors redirect doesn't seem to kick in and I'm left with a blank page?
I want to make All Methods about Error handling in asp.net some one device me at using global.asax what is global.asax?
how can i use it ?
I was given a web app written in VB.net. I am using VS2008. The project has a Global.asax page with Enums declared
Example:Public Enum eCurrentLoc as Integer
Admins
AdminTools
Home
LogIn
Status
End Enum
But in the web application itself I get errors on this line of code:
Ads = Global.eCurrentLoc.Admins
I get the blue scwigly line under Global.eCurrentLoc
The error states 'eCurrentLoc' is not a memeber of '<Defaults>'
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 ?

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)
}
Global.asax
void Application_Error(object sender, EventArgs e)
{
Exception err = Server.GetLastError();
Session["error"] = err.InnerException.Message;
}
web.config
<customErrors mode="On" defaultRedirect="CustomerPage.aspx"></customErrors>
CustomerPage.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
if (Session["error"] != null)
{
Response.Write(Session["error"].ToString());
}
It does not work. How to call a procedure?
my Global.asax file looks like this -
[Code....]
From some reason that I am not aware of Application("vCounter") reset to its initial value (0) every hour (i think).
I have an asp.net 4.0 application that is using forms authentication set to a timeout at 45 minutes. I would like to redirect the user to a timeout page when the session has expired. Can anyone tell me how to do this? I am running .net 4.0.
web.config has:
<authentication mode="Forms">
<forms name=".ASPXAUTH" loginUrl="~/Login.aspx"
defaultUrl="~/Default.aspx" protection="All" timeout="45"
requireSSL="false">
</forms>
</authentication>
Global.asax.cs file has:
void Session_End(object sender, EventArgs e)
{
Response.Redirect("~/Timeout.aspx");
}
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?

I am redirecting user from http to https if page is not secure from global.asax file in application_Begin event
But there are some pages in which i don't want to redirect to https page. I want to detect any form element which will tell me weather page should be secured or not. but when i check Requet.Form[_Viewstate] it gives me null value. Right now i check like Request.PhysicalPath.ToLower().IndexOf("test.aspx") ==-1 && !page.IsSecureConnection-> redirect to secure page but in future there will be more page which should be on http.
Is there any general way to redirect to https if page i added any hidden field on page "hfIsHttps=1" and detect that element if 1 then go other wise don't go Following is my code global.asax in application_Begin event
[code]....
I want, instead of hard core check for perticular page there should be general way, like each page itself should tell weather it should be for http or https
I have a ASP.NET/C# web application. There is an object instantiated in the Global.asax that I'll call g_objVariable. What I would like to do is reference one of it's properties in the ASP.NET page itself, like this.
The g_objVariable's Prop1 value is: <%=AppNameSpace.Global.g_objVariable.Prop1.ToString()%>
I get it to see the reference, but it keeps telling me that due to it's protection level I can't access it. I have it set to 'internal static'. What would be the least level I could set it to, but still allow the page to access it?
My website needs hit counter. i have created hit count in global.asax page, which works fine. Now i wanted to display hit count in all pages. so, do i have to use mater page or function to all in every page.
View 3 RepliesI have added global.asax file in my webservice project. in webservice project i have one class file name as 'Class1.vb' in this class contain some methods() , i want to access those methods from 'class1.vb' in global.asax.vb file. any body knows how to access those methods in global.asax.vb. file

I need to call this method in global.asax and save that value in session. I need to use this session value i need to use this Session value and assign that to label in Masterpage. I did not use global.asax before. And what should be the input to method... i have seen only Request is have the returntype HttpRequest. So i thought of giving that.

i am trying to do this is Global.asax file. but this method is not executed when the browser closes. or am i doing something wrong?
I want to protect one file in a subdirectory with Global.asax. (I know that this isn't the conventional way of going about this) but it works on my computer and not on the server.I have a global.asax file in my root dir and Application_BeginRequest checks if the user is requesting a particular file. If they are logged in, it allows access. If they are not logged in they are redirected to the default page.My problem is this: My code works on my personal computer but does not work on the server. Do I have to configure a setting in the web.config or adjust something on the server? Code:
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
Dim fullOrigionalpath As String = Request.Url.ToString.ToLower
'PROTECTED FILE
If fullOrigionalpath.Contains("/uploads/groups.xls") Then
If HttpContext.Current.User.Identity.IsAuthenticated = False Then Response.Redirect("~/login.aspx")
End If
End Sub
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 am have declared a session variable in login page of my application. I want to access that session variable in Application_BeginRequest of global.asax file. But I am not able to do it. Could you please suggest how to access the session variable in my global.asax file
void Application_BeginRequest(Object sender, EventArgs args)
{
string language = HttpContext.Current.Application["language"].ToString();
}
I need to set a page (unavailable.htm) whenever any user try to access the website from particular time (i.e 1-2 pm). I am using Application_BeginRequest() to check on the hours and redirecting to unavailable.htm. It does not work because it keeps redirecting endlessly to unavailable.htm. Below is my code :
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
I'm working on a new C# web application in Visual Studio 2010, and am having problems reading a value in Web.Debug.Config from the GLobal.asax.cs file.
In the Application_Start event I've got the following code:
Application.Add("AppID", ConfigurationManager.AppSettings.Get("AppID"));
I also tried:
Application.Add("AppID", ConfigurationManager.AppSettings["AppID"]);
And in the Web.Debug.Config file I have the following:
<applicationSettings>
<add key="AppID" value="123" />
</applicationSettings>
I also tried:
<appSettings>
<add key="AppID" value="123" />
</appSettings>
And I tried having it in a file path, like so:
<appSettings file="C:MyPathappSettings.config"/>
When running in debugger, I've got a break-point in the Application_Start event in Global.asax.cs. It hits the break point, but in all cases the value coming back from ConfigurationManager is coming back null. What am I doing wrong?
