Sending and receiving emails has now become an important task in our daily life. Email service providers such as Hotmail, Gmail & Yahoo have provided their SMTP Ports so that third party developers can use them in their applications.

In visual basic.net we use SMTP i.e Simple Mail Transfer Protocol which helps us in composing electronic mails and sending them to various sources.

3. Add a button and change its text to Send.

4. Double click button to switch to code view and paste the code given below.

Dim MyMailMessage As New MailMessage() Try MyMailMessage.From = New MailAddress("youremail") MyMailMessage.To.Add(TextBox1.Text) MyMailMessage.Subject = TextBox2.Text MyMailMessage.Body = TextBox3.Text Dim SMTP As New SmtpClient("smtp.gmail.com") SMTP.Port = 587 SMTP.EnableSsl = True SMTP.Credentials = New System.Net.NetworkCredential("youremail", "yourpassword") SMTP.Send(MyMailMessage) MsgBox("Your Mail has been Successfully sent") TextBox1.Clear() TextBox2.Clear() TextBox3.Clear() TextBox1.Focus() Catch ex As Exception MsgBox(ex.ToString) End Try

5. Change youremail with your current email address and yourpassword with your email ID’s password. Don’t forget to import the following namespace: Imports System.Net.Mail

That’s it!! Run your Project and send a test email.

Note: It works only with Gmail Account because we have used Gmail’s SMTP Port.
