[2005] Help with this dll???

[noahssite]

Hello i have downloaded a Windows Live Messanger SDK Client...

It contains an example of a program which allows you to log in, go into the options of your msn etc...

I quickly loocked through the code, it was in C++ which i dont know very well, i found that at the top of the C++ page it said 'using' and then a name. I then tried to do the following to explore the features.

Imports Microsoft.WindowsLive.Id 'C:\Program Files\Common Files\Microsoft Shared\WLIDClient\Microsoft.WindowsLive.Id.Client.dll
 
Public Class Form1
    Friend Identity As Microsoft.WindowsLive.Id.Client.Identity
    Friend IDManager As Microsoft.WindowsLive.Id.Client.IdentityManager
    Friend LogOnExpection As Microsoft.WindowsLive.Id.Client.WLLogOnException
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
    End Sub
End Class

I wrote Identity then wrote a . to see the features. I was having trouble with them... I don't understand how to retrieve the users username. Does the user have to bo on to use this function?... I had a bit of trouble understanding...
