For example: I'm asp on error goto label using the Mail.SendMail function but when switching on the testing server it doesn't work, which is normal. I want to test if mailing is possible, if not then continue and/or show a message.

On Error Goto Handler
can code in JScript or VBScript which do have the construct or you can fudge it in your code. Using JScript you'd use the following type of construct: In your ASP code you fudge it by using on error resume next at the point you'd have a try and checking err.Number at the point of a catch like: <% Dim i ' Turn on error Handling On Error Resume Next 'Code here that you want to catch errors from ' Error Handler If Err.Number <> 0 Then ' Error Occurred / Trap it On Error Goto 0 ' But don't let other errors hide!

Asp On Error Goto 0
a minute: Sign up What does the “on error goto 0” and “error resume next” in old ASP mean? up vote 5 down vote favorite I am working with old ASP code and I am not sure about semantics of http://stackoverflow.com/questions/472558/is-try-catch-like-error-handling-possible-in-asp-classic on error goto 0 and error resume next construction. Can you recommend me some useful resources or enlight me directly? asp-classic vbscript share|improve this question edited Dec 1 '11 at 20:02 Joel Coehoorn 248k92440661 asked May 13 '09 at 8:12 Jakub Šturc 17.9k196996 add a comment| 5 Answers 5 active oldest votes up vote 4 down vote accepted On error resume next: If there is an exception in the program, just ignore it and continue to the next statement. Considered very bad http://stackoverflow.com/questions/856710/what-does-the-on-error-goto-0-and-error-resume-next-in-old-asp-mean/856740 and ugly, and rightly so in my opinion. It's like having a big: try { // your code } catch { // nothing! muhaha } in every method of your code (or worse, around the whole program). On error goto 0: disables any error handler that is defined in the current procedure. It's like having a big try-catch around your code, which gets disabled as soon as its hit this line. For more information, see the MSDN. share|improve this answer edited May 13 '09 at 8:32 answered May 13 '09 at 8:20 Razzie 19.6k104861 2 +1 Yes. I just discovered this: If you use On Error Goto 0 then every other On Error statement in the procedure becomes disabled. That was totally unexpected. I thought that the documentation was saying that only the last executed error handler is disabled. I expected that if the code reaches another error handler that it would be enabled again but it isn't. –authentictech May 9 '14 at 14:54 add a comment| up vote 4 down vote Have a look here: http://www.powerasp.com/content/new/on-error-resume-next.asp share|improve this answer answered May 13 '09 at 8:20 Seb 411 add a comment| up vote 3 down vote on error go to takes the execution code to a specific code book mark defined in the page.this is useful when you want to perform anything in case an error is encountered.

It's quick & easy. script for on error goto errhandler P: 83 MATTXtwo is't asp supported for on error goto error handler? if so can anybody give me some hint for it... i need to make my page get to other link if detecting an error Nov 5 '08 #1 Post Reply Share this Question 3 Replies Expert 100+ P: 979 DrBunchman Hi MATTXtwo, The first thing to do is to put the following line at the top of your page: Expand|Select|Wrap|Line Numbers <% OnErrorResumeNext %> This tells the interpreter to ignore any errors and carry on processing the script. The next thing you need is a bit of code to trap any errors which occur: Expand|Select|Wrap|Line Numbers <% IfNotErr.Number=0Then Response.WriteErr.Description Error.Clear EndIf %> You can put whatever you like in this second bit of code to handle the error as required. Hope this helps and let me know how you get on, Dr B Nov 5 '08 #2 reply P: 83 MATTXtwo Expand|Select|Wrap|Line Numbers <% OnErrorResumeNext %> Expand|Select|Wrap|Line Numbers <% IfNotErr.Number=0Then Response.WriteErr.Description Error.Clear EndIf %> Thanks DrB ... Can I do like this.. ON ERROR code top of page iif statement bottom of page? and can this code catch all error on pages? Nov 5 '08 #3 reply Expert 100+ P: 979 DrBunchman Yes, that's how it should work. Give it a go and let me know what happens.
