global file email send

--------------------------------------------------------------------------------

guys, i'm developing an application and want to send an email with an error if it occurs to the administrator... i tried the following below but can't get it working.

I did have it working a while ago...but have had no success with this.... any ideas?

heres the code (simplistic) from the global.asax file:

<%@ Import Namespace="System.Web.Mail" %>
<%@ Import Namespace="System.text" %>
<%@ Import Namespace="System.web" %>
<%@ Import Namespace="System.web.sessionstate" %>
<%@ Import Namespace="System.Web.Mail" %>
<%@ Import Namespace="System.Text" %>
<script language="VB" runat="server">

Public Class Global
Inherits System.Web.HttpApplication

Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)


Dim mail As New MailMessage()
Dim ErrorMessage = "The error description is as follows : " & Server.GetLastError.ToString
mail.To = "(e-mail address removed)"
mail.Subject = "Error in the Site"
mail.Priority = MailPriority.High
mail.BodyFormat = MailFormat.Text
mail.Body = ErrorMessage
SmtpMail.Send(mail)

End Sub

End Class



i have even tried a simple reponse.write in the application_error and can't seem to make it trigger! Can someone point me in the right direction?

thanks
 
hai paul,
Just Try giving SmtpServerName/IP it may help u

System.Web.Mail.MailMessage mailer = new System.Web.Mail.MailMessage();
mailer.To = ToAddress;
mailer.From = FromAddress;
mailer.Subject = Subject;
mailer.Body = Body;
SmtpMail.SmtpServer = SmtpServerName/IP
SmtpMail.Send(mailer);

Good Luck
Mahi
 
thanks for the help guys....


i've now tried just this in my global.asax file and i just can't seem to trigger anything


<script language="VB">



Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
response.write("hello")
End Sub


</script>



any ideas?
 
Paul,

You cannot use Response.Write in global.asax

Where (in what page) would
the Response object write "hello" to ?

can you post the code that causes the error (or add one). if the originating
error is contained within a try / catch statement. you may need to rethrow
it for the application error event to fire

Cheers, pete
 
Referencing the Session, Request, Response or Page
objects within application scope generates an error.

Application_Error only fires when an unhandled
exception is thrown, so you can't just Response.write
from it

You could *define* what happens when an
unhandled exception occurs, but you can't
do anything else within the Application_Error event.

Errors that are handled with error trapping
code (such as Try/Catch blocks) will *not*
cause the Application_Error event to fire.

It's impossible for response.write("hello")
to occur.within Application_Error.

right...

heres my page to generate an error when i click on the button..

<%@ Page Language="VB" %>
<script runat="server">

' Insert page code here
'

Sub Button1_Click(sender As Object, e As EventArgs)

throw(new ArgumentNullException())

End Sub

</script>
<html>
<head>
</head>
<body>
<form runat="server">
<asp:Button id="Button1" onclick="Button1_Click" runat="server" Text="Button"></asp:Button>
<!-- Insert content here -->
</form>
</body>
</html>
------------------------------------------------------------------>


and heres my global.asax file code....


<script language="VB">



Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
response.redirect("error.aspx")
End Sub


</script>
 
Hi, Paul.

If all you want to do is redirect the user to an error page,
you're far better off using a custom error page.

See
http://msdn.microsoft.com/library/d...us/cpgenref/html/gngrfCustomerrorsSection.asp
and
http://msdn.microsoft.com/asp.net/a...l=/library/en-us/dnaspp/html/customerrors.asp

There's a great source code sampler at
http://download.microsoft.com/downl...4057-af24-9e1a5b34b3dc/CustomErrorsSample.msi
( 341KB )

There's a very simple walkthrough for custom error reporting at
http://www.c-sharpcorner.com/Code/2002/May/CustomErrorHandlingASPNEt.asp
It explains the basics without much ado.

i have managed to get my error email working.

But I can't seem to trigger my global.asax error function,no matter what I do!

The web config file is fine and works by redirecting on an error, but I need to be able to send the email from the global.asax file but it just doesn't seem to trigger at all.

Any ideas?
 
thanks for the help guys,

the problem was a simple one

my global file was not in the root folder... i thought it was but it wasn't ... the folder i was using need to bee set to an application is IIS on the server.

Thanks again
