Visual Basic Help Me Please.

So when I made an emailer. This is what it looks like:

I had this as the code:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim smtpServer As New SmtpClient()
        ProgressBar1.Value = +7.5
        Dim mail As New MailMessage
        ProgressBar1.Value = +15
        smtpServer.Credentials = New Net.NetworkCredential("[email protected]", "My password is here, but I don't want u guys knowing it ")
        ProgressBar1.Value = +20
        smtpServer.Port = 587
        ProgressBar1.Value = +30
        smtpServer.Host = "smtp.web.de or smtp.gmail.com"
        ProgressBar1.Value = +40
        smtpServer.EnableSsl = True
        ProgressBar1.Value = +50
        mail = New MailMessage()
        ProgressBar1.Value = +55
        mail.From = New MailAddress("[email protected]")
        ProgressBar1.Value = +56
        mail.To.Add(TextBox1.Text)
        ProgressBar1.Value = +60
        mail.Subject = TextBox2.Text
        ProgressBar1.Value = +75
        mail.Body = TextBox3.Text
        ProgressBar1.Value = +85
        smtpServer.Send(mail)
        ProgressBar1.Value = +100
        MsgBox("Mail Sent !")
        If MsgBoxResult.Ok Then
            ProgressBar1.Value = 0
        End If

When I send an email I get this:

If you know how to fix this please reply

This is Visual Basic .NET, not C++.

I've never worked with sending mail from a .NET program, but you can try wrapping that smtpServer.Send(mail) line in a try...catch block and displaying a MessageBox with the exception converted to a string. It will tell you what went wrong.

I've worked with this b4. Can't remember though.

I know this is super old, but I just read it now, so this is really for the benefit of someone with a similar issue and seeing as no one else has posted a solution I thought I would way in.

 

It has been a while since I programmatically sent mail, but I swear the SMTP port should be 25

What a bump.  I almost thought Karnage was active again .  Anyways, SMTP can be on any port really and it typically isn't 25 anymore because of additions of TLS or SSL

Hmm idk then. Maybe something off with "smtp.web.de or smtp.gmail.com". Should the 'or' be part of the literal? Not sure. Never use VB anyway.
