How to mail using vb.net windows form

[somtabu]

actually i have used mail on vb.net windows forms

i have used this code for this

Imports System.Net.Mail  
 
'Inside the form’s code window:
 
Public Sub SendAnEmail(ByVal MsgFrom As String, ByVal MsgTo As String, ByVal MsgSubject As String, ByVal MsgBody As String)
 
        Try
 
            '  Pass in the message information to a new MailMessage
 
            Dim msg As New Net.Mail.MailMessage(MsgFrom, MsgTo, MsgSubject, MsgBody)
 
 
 
            '   Create an SmtpClient to send the e-mail
 
            Dim mailClient As New SmtpClient("127.0.0.1")  '  = local machine IP Address
 
            '  Use the Windows credentials of the current User
 
            mailClient.UseDefaultCredentials = True
 
 
 
            ' Pass the message to the mail server
 
            mailClient.Send(msg)
 
            '  Optional user reassurance:
 
            MessageBox.Show(String.Format("Message Subject ' {0} ' successfully sent From {1} To {2}", MsgSubject, MsgFrom, MsgTo), "EMail", Windows.Forms.MessageBoxButtons.OK, Windows.Forms.MessageBoxIcon.Information)
 
            '  Housekeeping
 
            msg.Dispose()
 
        Catch ex As FormatException
 
            MessageBox.Show(ex.Message & " :Format Exception")
 
        Catch ex As SmtpException
 
            MessageBox.Show(ex.Message & " :SMTP Exception")
 
        End Try
    End Sub

Then all that remains to do is create some calling code . This example uses a button click to send data that I type into four textboxes with self-explanatory names: (You can replace them with literal strings of your own)

 
  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
        SendAnEmail(FromBox.Text, ToBox.Text, SubjectBox.Text, MsgBodyBox.Text)
 
    End Sub

but it gives the error unable to find server 5.7.1 and mail sending is failed i

i have already configure iis and settings also smtp mail server but it can't work

when i have used on web application then it fine work so if you have any solution regarding this then plz help me

thanks in advance

using System.Web.Mail ;

MailMessage mailobj = new MailMessage();
mailobj.To = "[e-mail]";
mailobj.From = "[e-mail]";
mailobj.Subject = "Hi this is the test mail";
mailobj.BodyFor mat = MailFormat.Html ;
string strBody = "hi this is the test mail;
mailobj.Body = strBody;
SmtpMail.Send(m ailobj);

use the above code to send mail in C#.
