The truth re On Error Resume Next

[Laphan]

Hi Everybody

I put the On Error Resume Next command as the very first line in my ASP
pages, which may contain various inc files and sub-routines/functions, so
that I can try and stop the dreaded DB error messages displaying to visitors
and would-be hackers.

My question is, does this one statement at the top of the page cater for all
of the code that might be executed in the page, in the include files and in
sub-routines/functions or do I have to put the statement in certain places
as well?

The reason I ask is that I'm sure if I get one of my include file names
wrong it brings up an error rather than going straight through and
displaying a funny page.

I hope I don't have to put it in various places as I like to have this one
statement so that I can flip back and forth between live and dev time and
having to go into 'x' amount of pages to flip between these 2 states would
be tiresome.

Many thanks.

I can't say it better than this. (There are related articles about

IMO avoid "On Error Resume Next" as much as possible. It will just hide
errors instead of reporting them.

Another option (and my personal preference) is to use a custom error page
(see http://support.microsoft.com/default.aspx?scid=kb;en-us;224070) that
displays a friendly message and warn the dev team about the error (it can
even trap compile time errors)...

Just my 2 eurocents...

Oops. It would help to post the link, wouldn't it?
