Borland c++ & msn

heyz,
uhm.. I'm having big troubles with c++ and msn. My project is a dll that can be called from mIrc and that let's you control msn (changing status, nick). The only problem I have is how to do that. It's ez to do when I create a gui-interface. I just drop the msgr-component on it and I code.. the same in VB, but there I can't make a dll.. Big probs... Is there a way to solve my problem?
I'm also happy with some documentation on that matter.. But not the msn-apiHelp you get on microsoft.com.. that I already have..
anyway... hope you can help me 'cause it's causing sleepless nights :)

greetz,
