In preparing to set up email, I copied the below code straight out of the Beginning ASP 3.5 book (p309). Instead of using the Page_Load event, I used a Button_Click. But other than that, it’s the same code. I also set up my web.config file as instructed.
Yet when I click to run the email, I get an error at the first DIM stmt,
Dim myMessage As MailMessage = New MailMessage()
Error: “The specified string is not in the form required for an e-mail address."
Has anyone else encountered this problem?
Thanks, Jack Kunkel
code
Imports System.Net.Mail

PartialClass Email1
Inherits System.Web.UI.Page
ProtectedSub Button1_Click(ByVal sender AsObject, ByVal e As System.EventArgs) Handles Button1.Click
Dim myMessage As MailMessage = New MailMessage()
myMessage.Subject = "Test Message"
myMessage.Body = "Hello world!"
myMessage.From = New MailAddress("[email protected]", "Sender Name Here")
myMessage.To.Add(New MailAddress("[email protected]", "Receiver Name Here"))
Dim mySmtpClient As SmtpClient = New SmtpClient()
mySmtpClient.Send(myMessage)
EndSub
EndClass
/code

Hi there,

Is this all the code in the page? I just ran your code and it runs fine for me. Also, the error you get doesn't make a lot of sense. When creating a new MailMessage you're not required to enter a from address yet (with the empty constructor you are using) so there's no reason for .NET to check the address there.

Can you provide more details? Where and when do you get this error? What version of VWD / .NET are you running? Can you show us a screen shot or describe a reproducible scenario?
