On Error Goto Line
errors etc, but I've encountered a different 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 on error goto 0 doing in background). 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. 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| Did you find this question interesting?

Other Stuff How To Use On Error Resume Next Often when using ASP or Active Server Pages http://www.powerasp.net/content/new/on-error-resume-next.asp 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. http://www.codeguru.com/csharp/.net/net_general/debugginganderrorhandling/article.php/c19557/ASP-and-the-Error-Handler.htm Generally if an error is encountered in your .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, on error 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. 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. on error go <% 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 text file when they sign in to a site. We add "On Error Resume Next" here simply so no nasty error message come up if by chance write permissions to the text file do not exist. <% Set ObjMyFile = CreateObject("Scripting.FileSystemObject") Err.Clear On Error Resume Next LogFileName = "aspprotect.log" LogFileDirectory = "c:\somedirectory" 'Open Text File.. If doesn't exist create it and append to it .. If exists just append to it Set WriteMyData = ObjMyFile.OpenTextFile(LogFileDirectory & "\" & LogFileName,8,True) RowHeaderString = Session("User_ID") & vbTab RowHeaderString = RowHeaderString & Session("Username") & vbTab RowHe
