If somebody want to learn MSN Messenger Activity developing there’s a guide how to start it.
I think every important thing is written there. I’ve included the Help file (CHM) where you can read to file. messengerp2p.zip (585.1 KB)
If you can’t open the file because you get an IE error, watch this reply: Messenger plus script development
Anyways thanks to the OhHelloThereImTheGuy and the other guys who’s shared this guide to us.
