Asp On Error Goto 0
vote 6 down vote favorite Good day all, 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 classic asp throw exception features in the code like: Do while not rs.EOF query = "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

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 displaying a message but the script keeps going:On Error Resume NextDim xx = 1/0If Err.Number <> 0 ThenResponse.Write "Error: " & Err.DescriptionEnd IfResponse.Write "Note, this line here still executes and prints this text." Stop Suppressing
an error occurs 'Do somethign that might cause an error If Err.number <> 0 Then ' check if any errors were raised and handle them 'Handle the Error response.write(Err.Description) End If On Error GoTo 0 ' turn off resume next 5e4aaed3-49dd-4e0e-bb35-c74f4269a1da|0|.0 Tags: on error resume next, asp classic debugging ASP Classic E-mail | Kick it! | DZone it! | del.icio.us Permalink | Comments (0) | Post RSS Related posts.NET State DropDown 1:
