I have a .net web application and in my config file i have

<customErrors mode="On" defaultRedirect="~/error.aspx" />
Then on the error page I use Server.GetLastError.ToString which is not working it returns "Object reference not set to an instance of an object."

How do i get the error the redirected the user to the default error page so i can correct it.

Thank you

try this
Sub Page_Error(sender as Object, e as EventArgs)

  dim PageException as string = Server.GetLastError().ToString()
  dim strBuild as new StringBuilder()
  strBuild.Append("Exception!")
  strBuild.Append(PageException)

  Response.Write(strBuild.ToString())
  Context.ClearError()

End Sub

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Ops, i just posted my comment on the wrong thread. I added the below code and placed a break point on the sub you told be to add but it never gets called on my generic error page that the web.config redirects it to. What am i missing?

Thank you for your patience
Imports System.Web
Imports System.Web.SessionState
Imports System.Web.Mail
Imports System.Diagnostics
Partial Class Sessions
    Inherits System.Web.UI.Page
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
    End Sub
    Sub Page_Error(ByVal sender As Object, ByVal e As EventArgs)
 
        Dim PageException As String = Server.GetLastError().ToString()
        Dim strBuild As New StringBuilder()
        strBuild.Append("Exception!")
        strBuild.Append(PageException)
 
        Response.Write(strBuild.ToString())
        Context.ClearError()
 
    End Sub

Open in new window

but this is the generic page that the web.config file calls when the application has an error. If i force an error then the server,getlasterror will retun the wrong error wont it ?

see this Page_Error error call when that page has error , for application related error you need to write code in global.asax in application_error event
