Classic Asp Throw Exception
problem. My (Classic ASP) page works fine, most of the time. Some users complain of an error on the page, couldn't duplicate yet. I tried error handling but On Error Resume Next does not help me with this situation and On Error Goto causes the page not to work and constantly throw an error (which looks like a 500, but that might be because of handling IIS is doing in background). It happens whether I write Goto 0 or on error resume next vbscript Goto [label] without a difference if the label exists or not. What might be causing this? asp-classic error-handling share|improve this question asked Nov 7 '12 at 8:13 JNF 3,01911444 add a comment| 2 Answers 2 active oldest votes up vote 6 down vote accepted On Error GoTo label is not supported in ASP you begin an error trapping block using On Error Resume Next , check Err.Number to see if an error occurred, close the block using On Error GoTo 0. See this doc and this thread share|improve this answer edited Sep 28 '13 at 5:49 answered Nov 7 '12 at 8:36 SearchAndResQ 2,04441223 So, I need to If Err.Number <> 0 after each possible problem. And hope things work if I miss one of those... –JNF Nov 11 '12 at 5:56 1 And remember to clear the Err object after a problem, if you want to carry on and check it again later! –Magnus Smith Jun 26 '14 at 10:20 add a comment| up vote 3 down vote Trying to trap every error using On Error Resume Next is not practical in larger ASP pages. Configure IIS to use a custom error page if a status code 500 is received. Format the following to suit... Set objASPError = Server.GetLastError response.write "Category: " & objASPError.Category & _ "ASPCode: " & objASPError.ASPCode & _ "Number: " & objASPError.Number & _

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 19.7k104862 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.

") 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. 107k16149195 asked Jul 3 '13 at 10:43 Matteo Bononi 'peorthyr' 77151749 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. 107k16149195 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("
