How do chat rooms work?

I was trying to figure out exactly how chat rooms work. Is there such a thing as a basic chatroom message tutorial?
Do the applets use sockets to connect to a Java Runtime program that echo's the messages back out to every applet?
I'm starting to think it would be ezier just to build a chatroom with Red5+Flash using the shared object.

Do you know what an applet is? Why do you think one would be involved in a chat app?
What's a "Java Runtime program", in your world?
What would Flash have to do with a chat room?
Basic idea:
Central server at known IP address and port.
All clients ("chatters") connect to that server.
When client A chats with client B, client A sends message to server, which in turn forwards it to client B.

  • How does chat applet works?

    how does chat applet works? What specific technologies should i learn to make a chat messaging work?
    thanks in advance for ur help...

    Chat applets work on sockets. Normally there are two parts. One server and one or more clients. The clients connect to the server and any message sent by a client is then distributed by the server to all the other clients.

  • How do I get my mic to work in Paltalk chat rooms?

    I recently joined up with Paltalk, a site that has hundreds of chat rooms with live audio and video, as well as a normal type message area. I can post but thats all and even that is very slow. I can hear and see the other chatters messages but I cannot figure out how to use a mic (built in or otherwise) and get it to work in the chat rooms. How do I use my mic in the chat room?

    Thanks but I have asked for their help several times and it's like talking to a wall. I was hoping someone here could help. Communicating with Paltalk is quite useless, nevermind trying to figure out how to report a bug with them.

  • How to create rooms for video chat

    Hi
    I am working with video conference application.I am new to fms.Does anybody please suggest and guide me how to create different video chat rooms.
    Your help is appreciated.
    Thanks,

    Regarding scripting there were no changes introduced - in the sense of the framework, SSAS, and the way you build apps (e.g. clocal/cglobal). There were of course some enhacements to the API though, as well as some utility methods e.g. client.getNextID(); But on a global scale no. This book is a must-read for anyone who plans FCS/FMS. U might also regard this title: http://www.amazon.com/Macromedia-Flash-Communication-Server-MX/dp/0735713332/ref=sr_1_4?ie =UTF8&s=books&qid=1276703184&sr=1-4. Although it doesn't present much of new info after u read Proggramming FCS book, but it does offer some insight into aspects not described in any of the resources, like server administration etc. Also note tha the latter title appeared just after the release of FCS.

  • How can I direct the right people to the right chat rooms!!!  Really Urgent

    Hi,
    Im trying to create a diary that invites people to a chat
    room (FMS) at a particular time on a particular date. Making sure
    that only the invited people end up in the right rooms.
    Is there anyway of capturing a server side (FMS) unique ID
    and then pull it back as so I can then point people who log in, to
    that chat app using the unique ID?
    This one is driving me potty and the project Im working on
    needs a solution as soon as possible
    ANY help with this would be really really appreciated.
    Thanks in advance.

    Try the Firefox SafeMode to see how it works there. <br />
    ''A troubleshooting mode, which disables most Add-ons.'' <br />
    ''(If you're not using it, switch to the Default Theme.)''
    * You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
    * Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
    ''Don't select anything right now, just use "Continue in SafeMode."''
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
    If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />

  • After updating my ipad2 to ios6 my favorite chat room is not working. They can see me but I can't see them.

    Before I updated everything worked fine.  This is thru safari on the full version of a website.  Now after I enter my chat room and everyone can see me and what I type but I can't see them.  I was on the phone with apple.  1st call, they had me empty cookies and cache, that didn't work. I did a hard reset? held the off button and the round button.  that didn't work, but I was able to see one persons "hi" post.  2nd call they had me do a reset, thru the general in settings(I was also transferred to a supervisor which makes me think that I am the only one with this problem).  I was able to see 5 people say hi, but still unable to see them after the intial. 
    I use to see the little pinwheel at the top left hand side next to ipad and the signal strength pinwheel all the time but now I don't see it doing that. While in the chat.
    Any ideas.  The supervisor sorta suggested tap-a-talk.  But I didn't want to spend the money if I dont have to and Im not sure it would fix this..
    I did notify the website the chat room is thru so they know also, but no answers yet.

    Hi
    Have you set the Quicktime settings, goto sys prefs/quicktime/streaming/streaming speed set what you get from your ISP go no higher then 1.5mbps(dont use automatic)
    In ichats prefs click on video and change bandwidth limit to NONE.
    Restart iChat.

  • How do I get an empty chat room to go away?

    I know there are similar questions on the board, but nothing I've tried has worked so far. When I log on, an empty chat room pops open. Before upgrading to 10.6, I used to get a prompt every couple months about this chat room, but it was so inconsistent, I never tried to get rid of it. Now its happening every time I log on. Suggestions?

    Hi,
    Welcome to the    Discussions
    In iChat Menu > Preferences > Messages do you have Save Transcripts turned On ?
    If so, do you also have the "In new Chat Window, Show..." option ticked ?
    Delete any Saved Transcript for this Blank room
    The Messages pane will tell you where they are stored at the Save Transcripts spot.
    You may have to delete com.apple.ichat.plist because in iChat 4 you could use an option to "Remember Open chats Across (iChat) Launch but this option is not there in iChat 5.
    This file has to be gone to manually in your Home Folder/Library/Preferences
    Unfortunately it will lose all the settings you have made in the iChat Preferences regarding Font choice,Colour, Bubble colour, Incoming Bubble and Font colour and Alert Messages, Save Transcripts and the Menu bar icon plus any Saved Status Messages you have made.

    Hi Surya,
    Do you want to show just 2 rows, one for an "Adjusted AC_41AB" and one for "AC_41ABC"?
    If so, could you not just choose AC_41AB and AC_41ABC as the Dimension Members, then create a local member to be the "Adjusted AC_41AB" which is a calculation of AC_41AB minus AC_41ABC. Then you could hide the non-adjusted AC_41AB row so that it's not visible?
    If I get a chance I will test it and let you know.
    Regards
    John.

  • No chat room; no information; no phone number. Nothing works at this site. My Firefox will not open.

    What more is there to say? Firefox does not open; Restore or Start new Session go nowhere. Close program does nothing. All I get is a white screen; the chat room in supposed to be open, but it is closed. I posted a question, received no response, and was asked to respond to nothing. There is no phone number, no chat room, and the information is useless. Nice work.

    Does anybody work at this company?

  • When I type a message on my wireless keyboard, in a chat room, when I hit enter to send it, it does not go...any ideas or help. I am wondering if somehow I have locked it, but not sure if I did...how to unlock it

    When I type a message in a chat room, on my wireless keyboard, hit enter to post it, nothing happens. I am not sure if somehow I have inadvertently locked the keyboard...and if I did...how do I unlock it!!

    I don't think you can lock your keyboard, but then again, I've been known to be wrong
    see if your wireless keyboard has become unpaired (I'm assuming here, that it's bluetooth).
    Make sure that the keyboard's batteries are okay, and that the power switch (if the keyboard has on) has been turned on, then go into Bluetooth preferences, and make sure your keyboard is discoverable, pairable and a favorite, and that Bluetooth is turned on. Re-pair the device with your iMac and it should respond. If not, you may have to delete it from the Bluetooth, add it again, and re-pair it, if that makes any sense to you. Sounds like you may also have some lag in replying in your chat room, maybe the chat program you are using might have a preference or two??
