i want to make it so, that when an error accurs, the people get redirected to an error page, and that the error is being send to me.



in the web.config file i added:
Code: 
<customErrors defaultRedirect="error.htm" mode="RemoteOnly" />



in the global.asax i added:

Code: 
 Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs) 
   'Fires when an error occurs
   sendmail(Server.GetLastError)
End Sub



with the function:

Code: 
 Dim mail As New MailMessage 
mail.To = """name"" <email@email.com>"
mail.From = """ Error "" <email@email.com>"

mail.BodyFormat = MailFormat.Html
mail.Priority = MailPriority.High
mail.Subject = "Error Report - " & Date.Now.ToString
mail.Body = ""
mail.Body += "<u><b>ErrorMessage:</b></u><br>"
mail.Body += Ex.Message.ToString & "<br><br>"
mail.Body += "<b>exception: </b>" & ex.ToString
mail.Body += "<br><br><b>Reported on: </b>" & Date.Now.ToString
SmtpMail.SmtpServer = "BEXXGHE01IS0020"
SmtpMail.Send(mail)



it works, i get an email when an error accurs and the user is redirected, but i always get something like this:



ErrorMessage:
Exception of type System.Web.HttpUnhandledException was thrown.

the error is always of the type System.Web.HttpUnhandledException, while i know the error should be of other types. anybody who knows what causes this and how to solve it?
 
Well the actual exception is of type: System.IndexOutOfRangeException, being caused by a datarow trying to read a row at position 4 - which it isnt finding. The answers to your questions are all in the exception message you have posted :)

In order to solve this, modify your code to stop trying to read rows which dont exist, if you arent sure whats happening there, then post the code which is actually throwing the exception so we can take it from there
