Hello friends.
I'm developing an application that is the exact clone of the Yahoo
Messenger with some added functionality.

In that added functionality I want to show which of the Buddy is
online/Offline/Invisible.
The online and offline was done and here is the path to get that thing
wokring http://opi.yahoo.com/online?u=userid&m=g&t=2(replace userid by
urs)

But I'm having hard time in finding any way which will let me get the
user's status who is Invisible.

I'm using .Net and C# for my application.

Thanks
