Sending an e-mail via VB.Net can be done easily with the following code. You can also modify the code to send e-mail via an ASP web page.
Add this line in your declarations area.
Next, create a subroutine by entering the following code:
Public Sub SendEmail(ByVal strTo As String, ByVal strSubject As String, ByVal strMessage As String)
On Error GoTo SEerrTrap
Dim emailMsg As New MailMessage("fromEmail@wherever.com", strTo, strSubject, strMessage)
'Settings for using G-mail. Replace the url with the url or IP address of your mail server
'and the port number with "25" for an inhouse mail server.
Dim emailclient As New SmtpClient("smtp.gmail.com", "587")
emailclient.EnableSsl = True 'Enables SSL. You likely will not need this unless you are using a G-Mail account to send mail.
emailMsg.IsBodyHtml = True 'Enables HTML e-mail bodies
emailMsg.Priority = MailPriority.High 'Sets the priority of the e-mail and how it appears on the recipients PC.
emailclient.Credentials = New System.Net.NetworkCredential("userID", "password") 'User ID and password for the SMTP mail server
MsgBox(Now & " Error " & Err.Number & " " & Err.Description & " in SendEmail")
Calling the subroutine with the appropriate variables included will send the e-mail via your SMTP server specified in the code.
