''' <param name="cc">Cc recepient</param>
''' <param name="subject">Subject of mail message</param>

Public Shared Sub SendMailMessage(ByVal from As String, ByVal recepient As String, ByVal bcc As String, ByVal cc As String , ByVal subject As String, ByVal body As String)
' Instantiate a new instance of MailMessage
Dim mMailMessage As New MailMessage()
' Set the sender address of the mail message
mMailMessage.From = New MailAddress(from)
' Set the recepient address of the mail message
mMailMessage.To.Add(New MailAddress(recepient))

' Check if the bcc value is nothing or an empty string
If Not bcc Is Nothing And bcc <> String.Empty Then
   ' Set the Bcc address of the mail message
   mMailMessage.Bcc.Add(New MailAddress(bcc))
End If

' Check if the cc value is nothing or an empty value
If Not cc Is Nothing And cc <> String.Empty Then
  ' Set the CC address of the mail message
  mMailMessage.CC.Add(New MailAddress(cc))
End If

' Set the subject of the mail message
mMailMessage.Subject = subject
' Set the body of the mail message
mMailMessage.Body = body

' Set the format of the mail message body as HTML
mMailMessage.IsBodyHtml = True
' Set the priority of the mail message to normal
mMailMessage.Priority = MailPriority.Normal

' Instantiate a new instance of SmtpClient
Dim mSmtpClient As New SmtpClient()
' Send the mail message
mSmtpClient.Send(mMailMessage)
End Sub
End Class
