web.config customErrors

[Tim]

I have a page that is not part of a project. So, it does not have a
web.config file.

The header of the aspx page looks like this.

Page language="c#" src="MyPage.aspx.cs" Inherits="MyPage" debug="true"

When I run the page from a machine other than the server and when
there's an error, I get an error saying I need to change my web.config
file so the customErrors = "Off". I would like to see the detailed
message.

As I said before, this is a stand-alone page and does not have a
web.config file. How can I make it so anyone who gets the error will
see a detailed message?

Thanks
