Application.Err or event

[Sal Young]

I need help figuring out why the Application_Err or event on my global.asax
is not working. When I run my web application, I do get an error on the
screen but no log file/record is created. Here is the code I have for the
Application_Err or in my global.asax:

Sub Application_Err or(ByVal sender As Object, ByVal e As EventArgs)
Dim unhandledExcept ion As Exception =
Server.GetLastE rror().InnerExc eption

If Not EventLog.Source Exists("Mileage Efficiency Calculator") Then
EventLog.Create EventSource("Mi leage Efficiency Calculator",
"Mileage Efficiency Calculator Log")
End If

Dim el As EventLog = New EventLog
el.Source = "Mileage Efficiency Calculator"
el.WriteEntry(u nhandledExcepti on.Message)
Response.Write( "An exceptin occurred: Created an entry in the event
log ")
Server.ClearErr or()
End Sub

Is this a permission issue? Is there something I need to set up so my
application has the rights to create the new log file?

Thanks for your help.

Hi Sal,

Yeah I think so. To check add your ASPNET/NETWORK SERVICE account
temporarily as an ADMIN user and see if it starts working. I wouldn't be
surprised if you don't need extended rights to create a new Eventlog source.

FWIW, I don't think it's a good idea to log stuff like that into the
EventLog. I would opt for an application specific log into an XML file in
the application directory or into a Database table. I would reserve the
EventLog for errors of more severity. Just my 2 cents <g>...

Rick,

Thank you for your prompt reply. I did try what you suggested and added the
ASPNET account as a Administrator and that didn't solved the problem.

I'm really opposed to logging errors in a database because sometimes we get
database timeout errors; therefore, we can't access the database to log the
error.

Is there some sort of error that occurs with the logging? If the log is not
being written to you should be able to trap the error that is occuring in a
Try/Catch blcok.

As to logging to file - I understand that issue, hence the other suggestion
to log to an XML or text file. Whatever works.
