How we can detect invisible users on Google Talk?

Here are steps:

   1. Set the chat as off the record with target user (how?). This can be done only when the other user is online. (need help?)
   2. Now try sending chat to that user when he is invisible or offline.
   3. If he is invisible, then he will receive chat.
   4. But if he Is offline, then you will receive error “<username> did not receive your chat”.

Explanation:

Point 1: When a chat is set off the record, it will no longer get stored in your Gmail account.

Point 2: When you send a chat message to offline or invisible user, it gets delivered by default. At receiving end if user is online, a chat screen pops up showing him your message. If he is offline, your chat message will go to inbox as a mail.

Now if you put together above points then you will notice that, when you set chat off the record it can’t be delivered to inbox as mail, so it will be delivered only if user is online (no matter if he is invisible).

GTalk (Google Talk), actuala versiune a aplicatiei desktop nu ofera posibilitatea schimbarii statusului in “Invisible” (adica sa nu apareti online in lista de prieteni GTalk). Aceasta optiune este in schimb disponibila prin interfata web, din Gmail Chat, dar doar daca este inchisa aplicatia GTalk Desktop.

Odata deschisa aplicatia desktop, statusul “invizibil” nu va mai fi disponibil nici in Gmail Chat. Pentru cei care doresc totusi sa foloseasca aceasta optiune intr-o aplicatie desktop, exista o alta versiune oficiala de GTlak: Google Talk Labs Edition .

GTalk Labs Edition, permite schimbarea statusului in “Invisible”, dar trebuie sa stiti ca acesta este lipsit de multe optiuni care se gasesc in Gtalk.

Lipsuri in Google Talk Labs Edition :

- nu permite transfer de fisiere prin IM
- nu are optiune de schimbare skin
- serviciile voice si mailvoice sunt inexistente
