There's no Try-Catch support in pre-.NET versions of VB, including VB 6, VBA, and VBScript. On Error Resume Next isn't so bad if you know how to use it correctly. –Cody Gray Feb 15 '11 at 8:35 Yeah, I am disappointed. :( On Error Resume Next used to be my favorite command back in middle school, when I learned VB 6... it quickly became my most hated command after I learned C#. I guess I'll use it but I really don't want to. –Mehrdad Feb 15 '11 at 8:44 See below for some tips on using it correctly! :-) –Mark Ribau Sep 8 '11 at 5:30 add a comment| 4 Answers 4 active oldest votes up vote 16 down vote accepted VBScript doesn't have Try/Catch.

This is why I always used Javascript when I could get away with it. –wcm Oct 1 '08 at 14:23 add a comment| 2 Answers 2 active oldest votes up vote 103 down vote accepted VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the reuslts of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation. On Error Resume Next DoStep1 If Err.Number <> 0 Then WScript.Echo "Error in DoStep1: " & Err.Description Err.Clear End If DoStep2 If Err.Number <> 0 Then WScript.Echo "Error in DoStop2:" & Err.Description Err.Clear End If 'If you no longer want to continue following an error after that block's completed, 'call this. On Error Goto 0 The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above. share|improve this answer edited Oct 1 '08 at 14:36 answered Oct 1 '08 at 14:11 Dylan Beattie 33.4k2096154 9 :( ...

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.C
