Asp Error Handling
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 = "UPDATE asp on error resume next ...." 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.
