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).
On Error Goto 0
It happens whether I write Goto 0 or 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.

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.

Syntax On Error GoTo line On Error Resume Next On Error GoTo 0 The On Error statement syntax can have any of the following forms: Statement Description On Error GoTo line Enables the error-handling routine that starts at line specified in the required line argument. The line argument is any line label or line number. If a run-time error occurs, control branches to line, making the error handler active. The specified line must be in the same procedure as the On Error statement; otherwise, a compile-time error occurs. On Error Resume Next Specifies that when a run-time error occurs, control goes to the statement immediately following the statement where the error occurred where execution continues. Use this form rather than On Error GoTo when accessing objects. On Error GoTo 0 Disables any

Other Stuff http://www.powerasp.net/content/new/on-error-resume-next.asp How To Use On Error Resume Next Often when using ASP or Active Server Pages with VBScript you will find it necessary to check for errors when you do certain things that may fail and then handle it accordingly. Things like opening a database connection or writing to a text file come to mind. Generally if an error is encountered in your on error .asp file, the processing of your script stops and an error message is returned to the browser. If you want to continue processing your page even if an error is encountered, include the following line at the beginning of your .asp file: <% On Error Resume Next %> That being said just ignoring errors in your code is not a very good idea. on error go What you really want to do is handle the error in some way. The example below opens a database connection and shows you how to trap a potential error and do whatever you want because of it. In this case we are simply displaying the error. <% ConnectionString = "DBQ=c:\inetpub\wwwroot\mysite\data\mydatabase.mdb;Driver={Microsoft Access Driver (*.mdb)};" '*** This code checks the ConnectionString info you entered and reports back the error code if it is not ok Err.Clear On Error Resume Next Set ConnPasswords = Server.CreateObject("ADODB.Connection") ConnPasswords.Open ConnectionString If Err.Number <> 0 Then Response.Write (Err.Description& "
") Response.Write("This means there is most likely a problem with the" & vbCrLf) Response.Write("""ConnectionString"" info that you specified.
" & vbCrLf) Response.End End If On Error GoTo 0 %> We put the "On Error GoTo 0 at the end because that will essentially end the "on error resume next" That is something you want to do so any later errors in your application do not get ignored without you knowing about it. Below is another example. In this example our application logs user info in a
