ASP.NET processing error

I am doing some research on how to globally handle errors in my ASP.NET application. I decided to use the web.config file with the following code:

<customErrors mode="On" defaultRedirect="errorpage.aspx">
</customErrors>

Here is my errorpage.aspx.vb code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim ex As Exception = Server.GetLastError
End Sub

The problem I am facing Server.GetLastError

ends up being nothing. What do I need to do to have access to the latest information about the error? Since it's on the asp form page, I don't need to add HttpContext.Current.

to Server.GetLastError

, right?

thank

You can catch global errors with global.asax .



The error page is loaded with a simple http redirect and unfortunately doesn't know what the last error is for a specific user.

Try using ELMAH to capture your errors. It is highly customizable and will do the processing in the background without informing its users. It can submit bugs and send them by email and / or save to the database. I use it in all my applications.
