Error tracing on page

[Patrick]

I understand it is built in behaviour that if an ASP.NET's web.config is set
to:
<customErrors
mode="RemoteOnly"
/>

then I only get a detailed error message on screen when the ASP.NET
application is executed on the IIS server itself. However, I note that
with the following

<customErrors
mode="Off"
/>

Whereas I could get a full detailed trace including line number and
stack-trace like the following on the IIS server on which the application was
developed (Windows XP Professional SP1, .NET Framework 1.1, Visual Studio
..net 2003):
Server Error in '/app8156' Application

How can I enable my test IIS6 server with ASP.NET Framework 1.1 to display
full debug information?

Many Thanks

Hi,

Welcome to ASPNET newsgroup.
As for the "full debug information" you mentioned, it was just as you have
found, depend on the configruation in the application config
file(web.config) 's

<customErrors ... /> element.

the default setting mode="RemoteOnly" all the Remote client side can't see
the detailed error info( exception message, call stack...). When we use
mode="Off" that means we disable customized error function so that all the
client (no matter local or remote) are able to view the detailed error.

Also, i'm not very sure on the

you mentioned at the end of your last message, do you mean that you'd like
to enable the displaying detail error info setting for all the ASP.NET
applications on your server or any other requirement? If you want to make
a machine scope configuration, you can consider setting this in the
machine.config so that by default all the asp.net application on that
server will override it.

Steven, Thanks for replying.

As you see from my original post, even with the following settings in
Web.config, I don't get the line number, of the error source when the ASP.NET
1.1 code (compiled from Visual Studio .NET 2003 on WinXP Pro SP1, IIS5.1) is
taken across to a shared development server running Windows Server 2003
IIS6.0 ASP.NET 1.1
<customErrors mode="Off" />

Could there have been any security restrictions that prevent the line
number, etc. from being displayed? Note, the .pdb file had indeed been
copied over!

Thank you for the response,

Based on my local test, we can correctly get the detailed error message and
line number in source code as long as we're deploying the "debug" version
of our applciation's assembly. If we change the assembly's build versino to
"release" , then the line number won't display (no matter you've provided
the pdb or not), since there' no symbol info in the assembly.

So have you checked whether the app's assemly you deployed to your 2003
IIS6 server is debug or release? If release, you can try changing it to
debug version and test again.

The project was compiled as "Debug", and the whole website was copied over to
the Windows 2003 server's IIS6's virtual directory.

So there are no security lock down that could prevent the line number from
being displayed?

Thanks for the response,

Yes, as long as the deployed assembly has the symbols associated with it,
we should be able to get the source code line number in the exception page(
generally the debug version is capable of this). I'm not sure whether your
certain web application dosn't behave like this. Have you tried some other
simple web applcation deploying on that iis6 server to see whether the
problem also occurs? Also, if you can repro this with a simple web
project, you can attach it to us so that we can perform some tests on our
side.
