    Re: avoid generic error

    Hey,

    You can add error handling at the application level, to trap unhandled errors, and show a more informative error. However, the best approach would be to figure out what the actual problem is. I am on my phone just now, but i will take a proper look at your code later.

    Re: avoid generic error

    It looks to me that you are getting an unhandled error on the page and in your web.config you have set "/ErrorPage.aspx" as the default or other page to go to in this event. The problem is /ErrorPage.aspx does not exist... and so you are getting a second error (404 not found).

    Check your web.config and that errorPage.aspx exists where you specify.
    The problem with computers is their nature is pure logic. Just once I'd like my computer to do something deluded.

          <error statusCode="404" redirect="filenotfound.aspx" />
        </customErrors>

    Re: avoid generic error

    Ok, so that is the first part of what brin was asking. Does that file exist on the server?
