Asp Error Number
I would like to ask a thing about on error resume next let's assume we have a loop to navigate through a recordset like: Do while not rs.EOF query = "UPDATE ...." conn.execute(query) rs.movenext loop i would like to be sure the UPDATE is going good, and i would like to check if there is some problems, so I have put a debugging features in the code like: Do while not rs.EOF query = classic asp throw exception "UPDATE ...." on error resume next conn.execute(query) If Err.Number <> 0 Then Response.write(Err.Number) response.write("
") response.write(Err.description) response.write("
") response.write(query) response.write("
") end if on error goto 0 rs.movenext loop the question is : during a loop, if it encounters an error, the next cycle will the error be there (and so triggers again the error block) ? or on error goto 0 will clear the Err object? in other words, will it works as a error handling? asp-classic vbscript error-handling share|improve this question edited Jul 3 '13 at 10:51 Alex K. 106k16146194 asked Jul 3 '13 at 10:43 Matteo Bononi 'peorthyr' 76451749 add a comment| 3 Answers 3 active oldest votes up vote 5 down vote accepted VBScript resets the error on goto 0: on error resume next i = 1 / 0 WScript.echo( err.number ) '' prints 11 (div by 0) on error goto 0 WScript.echo( err.number ) '' prints 0 (no error) There is also the explicit err.clear(). share|improve this answer answered Jul 3 '13 at 10:49 Alex K. 106k16146194 oh, nice to know the err.clear(), thanks ! :D –Matteo Bononi 'peorthyr' Jul 3 '13 at 10:53 add a comment| up vote 2 down vote The correct code to use is Err.Clear I have tested it with the following code <%on error resume next response.write (p(10)) Response.write(Err.Number) response.write("

Considered very bad 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

Tags: ASP , On Error Resume Next , trap errors , CDO , send email KB100411 ASP's ability to trap for errors is pretty weak compared to other languages. However, you can trap for errors, suppress errors, and stop suppressing errors. When an error is found, you can also handle it. Suppressing Errors To start trapping errors, add the following line:On Error Resume Next This will suppress all errors for the duration of the script. For example, normally the following code would cause the death of your code with a division by error message:Dim xx = 1/0 However, you can suppress the error as follows:On Error Resume NextDim xx = 1/0 The above code will cause NO error at all. Capture Error But Keep Going While trapping for errors, you can handle the error by inspecting the Err object. The following code snippet handles our division by zero error by displayin
