Using JScript you'd use the following type of construct: In your ASP code you fudge it by using on error resume next at the point you'd have a try and checking err.Number at the point of a catch like: <% Dim i ' Turn on error Handling On Error Resume Next 'Code here that you want to catch errors from ' Error Handler If Err.Number <> 0 Then ' Error Occurred / Trap it On Error Goto 0 ' But don't let other errors hide! ' Code to cope with the error here End If On Error Goto 0 ' Reset error handling. %> share|improve this answer edited Oct 17 '12 at 11:42 Shadow Wizard 49.2k1385131 answered Jan 23 '09 at 11:19 Wolfwyrd 10.3k42961 2 +1.

Forums Links DISCUSSIONARCHIVES DISCUSSIONARCHIVES2 DISCUSSIONARCHIVES3 BLOG We didn't realize the site was so popular. Other Stuff 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 .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. 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 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 = O
