favorite 9 What options are there in ASP Classic for error handling? For example: I'm using the Mail.SendMail function but when switching on the testing server it doesn't work, which is normal.

Vbscript Resume On Error
you will find it necessary to check for errors when you do certain things that may fail and then handle vbscript on error resume next it accordingly. Things like opening a database connection or writing to a text file come to mind.

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. http://www.powerasp.net/content/new/on-error-resume-next.asp 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& "
