no all you have to do is to add the system.web.mail to your project, then it will work, irrespective of whether this is a windows or web application.

in your applicattion first of all
use the project add refence to add the system.web.services

then in your form use:

Imports System.web.mail

before or after the Public Class or End Class statement, add the import statement

Imports System.web.mail

then in the body of your code:

dim m1 as new mailmessage
' set your own parameters
' use:
Smtpmail.send(m1)

thats it, it will work, the only thing is that when you send the message, if your are not currently connected to the internet, it will give you a warning that you are not connected.
