Can I trap on specific label, and not after the error occured.
(I know : on error goto my_label ...
but this does not work in ASP pages)
Thanks

Actually, you can never trap on an error that doesn't occur.

Use the same setup, and either handle the error instead of
Response.Write'ing it out, or call a function to handle the error and
return whatever you need to continue processing. You can even handle
errors based on the error number.

I used to have a link to a document on either ASPFaq or 4GuysFromRolla
about error trapping, but it's not in my links (or I saved the link on
another system...). A search on both doesn't really turn up what I
remmbered, but there's info out there.

You didnt understand me.
I meant that : the error occurred, but I don't want just after line that
cause the error, but to goto a specific label.
(on "error goto my_label" doesn't work on asp, but only on VB, and "on error
resume next" is not what I am searching for).

correction: not "asp", asp is not a language. It is a platform supporting
multiple scripting languages, including vbscript (which is what I'm sure you
meant to say instead of "asp", right?), jscript, etc.

but only on VB, and
"on error resume next" is not what I am searching for).

Sorry, but that's the only game in town when using vbscript. As somebody
else said, you can switch to using jscript in your server-side code,
allowing you to use try...catch...finally.
