I have a thread program with VB.net which is generating reports and sending emails in async way after it.

It is executed by batch file.

The problem I am facing is, .bat is closed when not all smtp server sendasync are completed. However, email could be received when I run in web application.

Therefore, no email could be received. How can I waiting for all SMTP SendAsync tasks before process end.

Private Sub Process()
 reportGenerating()
 fileZip()
 emailSend()
End Sub

Private Sub emailSend()
 'looping something and prepare message/attachements
 For xxxxxxx
   AddHandler client.SendCompleted, AddressOf SendMailCompletedCallBack
   client.SendAsync(message, id)
 Next
End Sub

What do you mean by *it is executed by a batch file* ? – preciousbetine May 24 '19 at 05:18
@Aron seems theres no await function in .Net 4.0 – Edmund May 24 '19 at 07:01
@preciousbetine using bat scripting language in notepad to activate program execution – Edmund May 24 '19 at 07:02
.net 4.0 is not supported anymore. Upgrade to .net 4.5.2 at the very minimum. – Aron May 24 '19 at 09:26
