CODE

Imports System.Web.HttpCookie
Imports System.Web.Mail
Imports System.Web.Mail.SmtpMail
Imports System.Web.HttpCookieCollection
Imports System.IO
Public Class WebForm1
Inherits System.Web.UI.Page
Protected WithEvents TextBox1 As System.Web.UI.WebControls.TextBox
Protected WithEvents Button1 As System.Web.UI.WebControls.Button

#Region " Web Form Designer Generated Code "

'This call is required by the Web Form Designer.
<System.Diagnostics.DebuggerStepThrough()Private Sub
InitializeComponent()

End Sub

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form
Designer
'Do not modify it using the code editor.
InitializeComponent()
End Sub

#End Region

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles Button1.Click
Dim mycookie As New HttpCookie("canada bank", "Your
transaction is completed successfully.")
'mycookie.Expires = System.Convert.ToDateTime(2)
Response.Cookies.Add(mycookie)
Dim msg As New MailMessage()
Dim strwriter As New StringWriter()
Dim txt As New HtmlTextWriter(strwriter)
txt.RenderBeginTag("head")
txt.RenderBeginTag("title")
txt.Write("thank you!")
txt.RenderEndTag()
txt.RenderBeginTag("body")
txt.WriteLine("thank you for transaction through canda bank!")
txt.RenderEndTag()
txt.RenderEndTag()
msg.From = "canada bank.com"
msg.To = TextBox1.Text
msg.Subject = "thank you for registering"
msg.Body = strwriter.ToString
msg.BodyFormat = MailFormat.Html
SmtpMail.Send(msg)
End Sub
End Class
