Hellol,

when you send your own presence to the server, your server starts sending the online presences of your contacts to you.
All contacts from whom you get no presence are offline.
If some contacts show not up correctly then there must be a problem on your server or the contacts server.

the server starts sending presence after you send your own initial presence.
You don't have to send your presence again to get presence updates. They come automatically as long as you are online or log off.

If you don't send your presence to the server the server also sends no presences from your contacts. This is useful for applications which don't need the presence.

which means the best time to send my presence is in OnRosterEnd .. when all the contacts r downloaded ..atleast in my case.. my problem occurred since in OnRosterItem i added contacts with default value of offline .. and i sent my presence in OnLogin.. so kind of sync problem was there..now that i put it in OnRosterEnd.. its solved.. but if anyone has good ideas on how to add roster items after login.. please reply..

you can add contacts at any time after login and will get their presences when your are subscribed to them.

Thank you

Please study the MiniClient example (add contact form).
There is all code you need.
