Need help with changing MSN Nickname using VB.NET

Hey.
I'm using VB.NET and I'm trying to change my nickname on msn but I can't seem to get it.
I've added the msn API references but there's no function there that changes the nickname.

Is there any way to achieve this?

I'm able to change my status but nothing more.
Also I'd like to know how to send an instant message using VB.NET.

This is what I got so far:
Dim msn As New MessengerAPI.Messenger
msn.MyStatus = 2 'Online
'---------------------------------------
Dim myConversation As msn.InstantMessage "sample@mail.com"
myConversation.TextBox = "Hello"
myConversation.Send()
'What I'd like to do but doesn't work
'-------------------------------------
msn.MyNickName = "My Changed nick name" 'Doesn't work.

have you tried msn.MyNick instead of MyNickName as on the msn sites and stuff like that they refer to it as a nick not a nickname or have you tried .MyName?

could work hope it helps
