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

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 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.
View 3 RepliesSo 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.
View 1 RepliesNormally 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.

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)

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 want to convert a List (of Long) into a string array.
Reason: it's a list of database IDs and I want to make a comma delimited string to pass into a stored proc.I tried this:
Dim commaDelimitedList As String = String.Join(",", itemIDList.Cast(Of String)().ToArray)
but I'm clearly not using the Cast correctly since it throws an exception:
System.InvalidCastException: Unable to cast object of type 'System.Int64' to type 'System.String'..
Is there a way to get Cast working for this, or am I stuck with ConvertAll and a delegate function?

View 2 RepliesI'm trying to make a hash calculator (For testing now)
I know that MD5 is a 1 way(Meaning that there is no decryption for it, yet)
now I was wondering if SHA-1 is a two way. Also, is there any other hashing method that are 2way?
reason is that I want to convert a long string (Lets say 550 chars) into something lower (From 550chars to something lower then 550chars)
I can use a Key, but every possibility will give me bigger length then the actual string.
