Trap errors - 2nd post

[Eitan]

Hello,
I want to emphasize a point for my prior posts :

How can I trap a message in ASP (not dotnet), to a specific label.

(I know : on error goto my_label ...
but this does not work in ASP pages)

Thanks

Whats wrong with Bob's answer to your other post concerning this?

One of the links that was provided showed an example, but here's a generic
example:

on error resume next
'bunch of statements
'statement that may generate an error
if err <> 0 then
'handle the error
response.write err.number & ": " & err.description
'use Select Case to tailor your action to specific error numbers
end if
'turn off error handling if appropriate (this is optional*):
on error goto 0


In addition, with ADO, you also can ustilize the connection object's Errors
collection (you still have to us on error resume next)

on error resume next
conn.execute querythatmayproduceerror
if conn.Errors.count > 0 then
for each adoerr in conn.errors
response.write "<BR>ADO Error #" & adoerr.number & "<BR>" & _
"DB Error #: & ": " & adoerr.nativeError & "<BR>" & _
"Description: " ": " & adoerr.description
'use Select Case to tailor your action to specific error numbers
next
end if

This would be better written like this:

on error resume next
'bunch of statements whose errors you wish to ignore
....
....
....
'statement that may generate an error you wish to handle
err.clear
....
if err <> 0 then
'handle the error
response.write err.number & ": " & err.description
'use Select Case to tailor your action to specific error numbers
end if
'turn off error handling if appropriate (this is optional*):
on error goto 0
