I am having problem to make email code working with VB .NET. I cann't even re-register Cdosys.dll file. I might have problem with my email server setting such as relay setting. Too many things to take care to make email code working. Looking back VB6, it is so easy to use Mapicontrols to manage emails, you can use default email program to send out email and you don't have to specify your mail server address in code. Anywa, is there a way in .Net doing the same thing, using the default email program and no mail server setting requirements?
