Hello,
I'm currently using Application_Err or method in Global.asax.cs to handle
errors.
Recently, I heard about Page.ErrorPage and plan to use it for handling
errors on certain pages. Are there any major difference in using these
methods? My concern is mainly on the restrictions imposed on using these
method.
In my old error handling routine, I tried to use Server.GetLatEr ror() to
get Exception object in the error page redirected by Response.Redire ct() but
failed, can I use this method to retrieve the exception object in the new
page if Page.ErrorPage is used instead?
Thanks a lot.
Regards,
Lau Lei Cheong

In ASP.NET you use structured exception handling via Try..End Try
statements. These statements allow you to catch exceptions, handle
different exceptions differently and keep your application going.
Try
some code that may throw an exception
Catch ex as Exception
some code to handle the exception
the exception itself is accessible via the variable name given to
it on the "Catch" line, so we can find out what type of exception we
have:
ex.getType.ToSt ring
we can get the exception message:
ex.message
End Try

You should also look into the
Microsoft.Appli cationBlocks.Ex ceptionManageme nt application block. It
provides some great functionality. Plus, they've already built and tested
it, so you don't have to.

True. However since the page is used to handle exceptions not on specific
task(such as when ASP.NET detects dangerous value in Request.Form[]) and
also unexpected server error, I think a general form of error handling would
be more appropiate.

I understand, but Page.ErrorPage isn't an error handler. It is just a
designation as to which page to show when there is an unhandled error.

Hi all,
If an error occurs in an aspx-page, you can configure the web.config in a
way that the user automatically navigates to a certain page (e.g.
error.aspx).
My question: is it possible to catch the stacktrace of the error in
error.aspx so it can be logged? The error has been catched somewhere in
order to perform the reroute to error.aspx. So where are the error-details?

I need help in implementing proper error handling.
I am trying to upload a file based on the sample code below. The code works
well except if the file selected is too big.
I do know about the maxRequestLength parameter of the <httpRuntime> section
and that works as expected. What I want is to enforce a max file size but
haven't been able to trap the error thrown when the file is too large and
that's where I could use some help.

This has been driving me crazy.
I have been trying to get the error handling working on my system and can
get parts of it working and others won't work at all.
I found that you can't access session variables from Application_Error
event, but I need to so I don't need to set up traces to see what they are
during an error. I am emailing the error condition to myself when it
happens.
