Vb msn api

Just wondering if anyone can point me in the direction of tutorials on the MSN Messenger API within VB?

I found one which has got me started - where you can sign in, change your status and see which contacts are online.

Can anyone tell me if there is a way which the user can actually send and receive the instant message within vb?

The tutorial I found simply acts as a" shortcut" - it opens the MSN programme.

I'd like mine to work so that the instant message conversation is displayed in a Listbox or whatever, and the user can type a message in a text box, hit send and it sends.

Thanks

Also open to do this with the Skype API if easier/ better

Messenger API only allows the development of applications used within the Messenger environment. The best help with the Skype API comes from Skype (I know, who'd have thought it?) Start at http://developer.skype.com/accessories
