you are right but but i am sure that protocol is open for public since Microsoft wants to make it compatible with AOL Messenger (which infact they did some time ago, but AOL rocks them back by changing Messenger protocol). i got its code though , but it is for linux including code for Yahoo Messenger, ICQ, Lazzard, AOL Messenger. its very difficult o go through it you can implement it easily from scratch rather then understanding it. anyhow ,,,,,,,thanks Aamir ======================================== Avenir Web's Computers Mailing List List Modes, Subscription, and General Info: Go to //www.freelists.org/cgi-bin/webpage?webpage_id=11 List Archives: //www.freelists.org/archives/computers Administrative Contact: weez@xxxxxxxxxxxxxx Get computer help: http://avenir.dhs.org ========================================
