Add This Code To Global.asax?
Dec 14, 2010
I need to add the code below to my global.asax file. It begins with a Sub Application_BeginRequest . My global.asax already has a section that begins with Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs) I'm assuming that I should not have two sections with Sub Application_BeginRequest I tried putting the core of the new code into my existing Sub Application_BeginRequest and it returns no errors but it when I try to view the website in VWDE 2010 it times out. Something is causing it to run or load slowly.
This is the code that I'm adding:
<script runat="server">
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
Dim url = String.Empty

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SplashScreen1.ProgressBar1.Value = 0

I've been given the thrilling task of re-writing our exception handling system. Whilst I will state that handling exceptions from an application-wide point of view isn't something we want, typically it's unavoidable when our team are understaffed for the sheer amount of work we need to push out the door, so please, no flaming the globalised solution to exception handling here

I need a function in global.asax file which gets called only once when user enter a page url. application_beginrequest gets called 50-60 times in a single page( as to render a page several requests go to server.)
i though of a solution - I can write my fucntion in global.asax and call it on page load of other pages but in that solution I need to call it in every page. I would prefer something which is to be done only in global.asax

I'm trying to use the Global.asax file in the root application of the website to catch requests for pdf files in the root that don't exist any more. I've configured iis to send pdf requests to asp.net. The whole thing works perfectly on development. It also works on the live system with missing .aspx pages, but not .pdf. Instead an "Error Code 64: Host not available". I'm using the Global.asax file to avoid the web.config and child applications (1.1 & 2.0) inheriting settings.[code]...

I have a huge website (containing around 5000+) pages. There is a theme functionality in the website where user can choose different colors for their profile. Now i want to use the ASP.net theme feature and put different CSS (for different colors) in the theme folder and in Global.asax i want check the user theme and render appropriate link element with the css. But my problem is, i am not able to access the Page element for adding the link in the page. Here is my code
Dim page As System.Web.UI.Page = TryCast(System.Web.HttpContext.Current.Handler,System.Web.UI.Page)
page.StyleSheetTheme = "Black"
But when i run this code I get a Null reference error.
P.s : My application is very huge so its not possible to have a master page or a base class and inherit it in every page.

I was wondering if there was a way to catch all unhandled exceptions in a visual studio project. My project does not have any files named global or global.asax so I was wondering if there was some other way to catch any and all unhandled exceptions? So far I've tried to put exception handling around specific blocks of code, but it doesn't have any effect.

So I handle all exceptions in my project within my Global.asax page. For example, on a random page I could have:[code]So my question is in the Application_Error method, do I need the try/catch block when trying to write to the database? I'm thinking I would in case something goes wrong with the connection, etc. - but is this really necessary? Also, what would I do in the catch block if there is an error? At that point I would be catching the error of logging an error which is confusing in its own right.

Normally I just redirect to a custom error page in on the Application_Error event, but I have a specific error for which I'd like to display an alert message while the user is still on the page which triggers the error. How can I make this happen?
I'm open to a modalpopup or any other type of error message, I just want to ensure the user stays on the page where they encounter the error.
This is in reference to this thread: [URL]
Here is the code I'm currently using:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)

I am handling errors via my global.asax in this method:
Dim CurrentException As Exception
CurrentException = Server.GetLastError()
Dim LogFilePath As String = Server.MapPath("~/Error/" & DateTime.Now.ToString("dd-MM-yy.HH.mm") & ".txt")
Dim sw As System.IO.StreamWriter = New System.IO.StreamWriter(LogFilePath)
[code]....
In my code I currently have no other error handling. Should I still insert try, catch, finally blocks?

In Global.asax, is there a way to handle SQL Timeouts elegantly, and display a message on the requesting page explaining the error? I know Global.asax has the Application_Error and Error events, but I'm not sure which (if any) I could use to accomplish this.
Related, can I access the page instance which raised the error that Global.asax is handling?

I have an application that contains both test code and production code. The test code points to the test files on the local machine while production is located on the server. I comment out the production code when testing. To save some time I figured I would create a Global Variable integer called pTest and encase the test and production code in a Case statement so that if I set pTest=1 then the test code will run and if pTest=0 then production code will run.

I am wondering if Global.asa can handle a procedure like this:
Protected Sub errore(tipo As Int16)
'Response.Write(Err.Description) 'or your own custom error message
Dim msg As String

The idea is to have a central place to put the routine in instead to copy it into every .vb file that belongs to each .apsx code file.

I am using module and all my variables are public .

I have a variable whose scope needs to be global, because it needs to be called in a function as well as in a button press. So I declared the variable in a Module so it would be global.The problem is that the value of this variable needs to be equal to the value of the text property of a textbox in the form.You enter a string into the textbox, in this case I entered "Hello". Then you click the button and it displays what you wrote.You click OK in that message box and change the value in the textbox. In this case I changed it to "Goodbye". Then I hit the button again, but the variable did not change values and the messagebox displays "Hello" again.

Here is the entire source code:
Module Module1
Public strDataValue = frmTest.txtDataValue.Text
End Module
[code]....
Note: This is just a demonstration of a problem I'm having in a much larger program so the variable does have to be global.

If we declare a global variable in module in vb.net, we can use that variable in anywhere in project.
How can we achieve same thing in C#.
Previously when we tried to convert a vb.net project to C#, we succeeded in removing the syntax error but we can't access global variable in a form.
I need some solution or guidance. Where I am making a mistake?

I want to create a dataset that I can access from any form. I already created the tables and columns using the dataset designer. I read that I can declare the dataset as public in a module, but when I try to access a table I have to put the name of the module in front otherwise I get a "Reference to a non-shared member requires an object reference" error. When I declare a variable as public in a module I never have to specify the name of the module to access the variable, so why do I need to do it for a dataset? The code in my module is:
