In th Professional ASP.NET 1.0 book there is an example of the Application_Error event in the global.asax.

I wrote this


    Public Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
        ' Fires when an error occurs
        Dim LogName As String = "Web_Errors"
        Dim Message As String

        Message = "Url: " & Request.Path
        Message = Message + " Error: " & Server.GetLastError.ToString

        If (Not EventLog.SourceExists(LogName)) Then
            EventLog.CreateEventSource(LogName, LogName)
        End If

        Dim Log As New EventLog

        Log.Source = LogName
        Log.WriteEntry(Message, EventLogEntryType.Error)
    End Sub

and modified the code on the default.aspx page so it will have an error. I run the application, get the error on the screen but no log file is created. Am I doing something wrong? or I need to modify the permissions of the asp.net user?

Hi there,

This is indeed a permissions issue. Earlier versions of ASP.NET allowed for LogSources to be created at run-time but that's not possible anymore. One way to fix this, is to give the ASPNET account the rights to the required registry keys.

However, it's recommended to create the required logs and sources at design / deployment time, and just write to them at run-time.

I found a link to the Exception Management Application Block. I'm going to give this a try. Thanks for your help.
