Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles Button1.Click

mail.Subject = TextBox1.Text
mail.Body = TextBox2.Text
SmtpServer.Send(mail)
MsgBox("ok!")
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
i tried the above code but got the error saying "timeout" and couldn't mail the textbox data
The time out is likely server related and has nothing to do with your text box value. Are you sure that you have permission to use yahoo's mail server to send email?
Try using "smtp.gmail.com" port: 587
Then enable the "access for less secure apps" option of your email account

Hello and greetings to all, I need some help. Below is my following code:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim Mail As New MailMessage
Dim SMTP As New SmtpClient("smtp.gmail.com")
Mail.Subject = "Security Update"
Mail.From = New MailAddress("XXXX#gmail.com")
SMTP.Credentials = New System.Net.NetworkCredential("XXXX#gmail.com", "XXXX")
Mail.To.Add("XXX#gmail.com")
Mail.Body = "Test"
SMTP.EnableSsl = True
SMTP.Port = "587"
SMTP.Send(Mail)
End Sub
However, I get the following Error When Ran: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.
The Password Is The Same To Login and is correct. What am I doing wrong? Also, I have a rich text box that I would like to be the body of the E-mail. I do not know how to do this. Please help.
This is a code snippet for sending email using vb.net:
Imports System.Net.Mail
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Credentials = New _
Net.NetworkCredential("username#gmail.com", "password")
SmtpServer.Port = 587
SmtpServer.Host = "smtp.gmail.com"
mail = New MailMessage()
mail.From = New MailAddress("YOURusername#gmail.com")
mail.To.Add("TOADDRESS")
mail.Subject = "Test Mail"
mail.Body = "This is for testing SMTP mail from GMAIL"
SmtpServer.Send(mail)
MsgBox("mail send")
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
End Class
Can I add CC and BCC address too? If yes, what are the possible codes?
e_mail.CC.Add("user#domain.com")
e_mail.Bcc.Add("user#domain.com")
Got it from myself :)
I really started to get confused about sending an e-mail to (example: test#test.com) through VB.NET and for sure using SMTP.
I want the mail to be sent when Button1 is clicked (example).
So I started by a code like that
Imports System.Net.Mail
Public Class MyProgram
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Using message As New MailMessage()
'set to the from, to and subject fields
message.From = New MailAddress("sender#sender.com")
message.[To].Add(New MailAddress("test#test.com"))
message.Subject = "Test"
'code the message body
Dim MsgBody As String
MsgBody = TextBox1.Text.ToString() & vbCr & _
TextBox2.Text.ToString()
message.Body = MsgBody
Dim client As New SmtpClient()
client.Host = "smtp.example.com"
client.Port = "465"
client.EnableSsl = True
client.Credentials = New Net.NetworkCredential("USERNAME#MAIL.COM", "PASSWORD")
client.Send(message)
End Using
'display submitted box
MessageBox.Show("Congrats", "Congratulations!")
'close form
Me.Close()
End Sub
End Class
And I get:
Next, I tried another code (which is) ...
Imports System.Net.Mail
Public Class MyProgram
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim Smtp_Server As New SmtpClient
Dim e_mail As New MailMessage()
Smtp_Server.UseDefaultCredentials = False
Smtp_Server.Credentials = New Net.NetworkCredential("USERNAME#MAIL.COM", "PASSWORD")
Smtp_Server.Port = 465
Smtp_Server.EnableSsl = True
Smtp_Server.Host = "smtp.example.com"
e_mail = New MailMessage()
e_mail.From = New MailAddress("sender#sender.com")
e_mail.To.Add("test#test.com")
e_mail.Subject = "Test E-mail Address Sent by My Program"
e_mail.IsBodyHtml = False
e_mail.Body = "Test"
Smtp_Server.Send(e_mail)
MsgBox("Mail Sent")
End Sub
End Class
And now I get the following in the Debugger:
And at last the e-mail isn't sent!
Please don't say "sender#sender.com" isn't configured as a sender e-mail address because it is!
I really need help!
Thanks. :-)
Can anyone help me. I've created a email program. I'm having an error when clicking on the send button. Here's my code:
Imports System.Net.Mail
Public Class frmEmail
Dim emailaddress As String
Dim password As String
Dim port As Integer
Dim host As String
Private Sub frmEmail_Load(sender As Object, e As EventArgs)
If emailaddress.ToLower.Contains("#gmail") Then
port = 587
host = "smtp.gmail.com"
ElseIf emailaddress.ToLower.Contains("#yahoo") Then
port = 465
host = "smtp.mail.yahoo.com"
End If
End Sub
Private Sub btnSend_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSend.Click
Try
Dim smtpServer As New SmtpClient
Dim mail As New MailMessage()
smtpServer.Credentials = New Net.NetworkCredential(emailaddress, password)
smtpServer.Port = port
smtpServer.Host = host
smtpServer.EnableSsl = True
mail = New MailMessage()
mail.From = New MailAddress(emailaddress)
mail.To.Add(txtTo.Text)
mail.Subject = txtSubject.Text
mail.Body = txtMessage.Text
smtpServer.Send(mail)
MsgBox("The mail is send!", MsgBoxStyle.Information)
Catch error_t As Exception
MsgBox(error_t.ToString)
End Try
End Sub
End Class
And I've got this error: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name:value
at System.Net.Mail.SmtpClient.set_Port(Int32 value)
***Edited forgot to modify it to the original code
Your sub
Private Sub frmEmail_Load(sender As Object, e As EventArgs)
doesnt run when the form loads.
Because of this port is set to the default value of 0
You need to tell VB.Net to run when the form loads like this
Private Sub frmEmail_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Also further on down the code, you might find that you get an error about authentication from the email server. If you get this, just below
Dim smtpServer As New SmtpClient
add this
smtpServer.UseDefaultCredentials = False
it might work.
i already know how to send a email using vb.net, however i cant figure out how to receive an email. I want to go into my email account and read a email and store it in a variable, is this possible? and if yes could any one give me some sample code, because that would be great.
just to get a good idea of what I'm using here's my code for sending a email,
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Credentials = New _
Net.NetworkCredential("trowbridge97#gmail.com", "qwerty1205")
SmtpServer.Port = 587
SmtpServer.Host = "smtp.gmail.com"
mail = New MailMessage()
mail.From = New MailAddress("trowbridge97#gmail.com")
mail.To.Add("trowbridge97#gmail.com")
mail.Subject = "Alarm"
mail.Body = "Some one is in your room"
SmtpServer.Send(mail)
MsgBox("mail send")
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
SMTP is used for sending email, not receiving it.
You need a POP3 or IMAP client. There are many commercial and free .NET libraries for both protocols.
