The SMTP server requires a secure connection or the client was not authenticated

Problem: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. c25sm1228430ika.11

Solution:

Public Shared Sub SendEmail()

Dim Message As New Net.Mail.MailMessage()

Dim FromEmail As New Net.Mail.MailAddress(“From Email Address”)

Message.From = FromEmail

Message.To.Add(“To Email Address”)

Message.Subject = “Subject of the Email”

Message.Body = “Body of the Email”

‘Message.SubjectEncoding = System.Text.Encoding.UTF8

‘Message.BodyEncoding = System.Text.Encoding.UTF8

‘Message.IsBodyHtml = False

‘Message.Priority = Net.Mail.MailPriority.High

Dim SmtpClient As New Net.Mail.SmtpClient(“smtp.YourEmailServer.com”, PortNo eg: 587 for gmail )

SmtpClient.EnableSsl = True

’smtp.DeliveryMethod = Net.Mail.SmtpDeliveryMethod.Network

’smtp.UseDefaultCredentials = False

SmtpClient.Credentials = New Net.NetworkCredential(“YourEmailAddress”, “YourEmailPassword”)

SmtpClient.Send(Message)

End Sub

Note: An important point to note is that you have to set the EnableSSl to True before you set the NetWork Credentials of your SMTP client.

How to call client-side Javascript function after an UpdatePanel asychronous (Ajax) request is over

If you are using AJAX then the only way i have found yet to give an alert to a user on return to the Asynchronous post back is to add an “end request” handler to the PageRequestManager.

In this way you can tell the request manager to run a javascript function on returning from a Asynchronous post back event of AJAX.

Code for doing this is :

function load()

{
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}

where “EndRequestHandler” will be the name of your javascript function you want to call.
Call the above function in Onload event of tag:

function EndRequestHandler()

{

alert(“You record has been saved successfully”);

}

Now If you want to give a different message based on your logic in server side code (code behind) then you can use a server side Hidden Field:

Set its value in server side code on Asychronous Post Back:

Protected Sub btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnCreateSample.Click

If condition Then

hdnValue.value = “do this”

Else

hdnValue.value = “do that”

End If

End Sub

Now you can check the value of this Hidden Field in your Client Side EndRequestHandler function and give a different alert to user based on its value:

function EndRequestHandler()
{
if (document.getElementById(‘<%= hdnValue.ClientID %>’).value == “do this”)

     {
          alert(“You record has been saved successfully”);
     }
     else
     {
          alert(“There is an error”);
     }
}
