So, you're not going to tell us what error you're hitting?

Would it be faster for me to write your application for you?

Hi Janna Ahmed,

The logout and start audio buttons are not working because, there are no click event handlers for those buttons. Adding the event handlers, and the logic for logging out of your room & start/stopping your audio should help you.




but could you explain how i add this events be couse i add but dosent work yet if im right will be like it

<s:Button x="19" y="497" label="start my audio" height="28" width="106" click="start my audio_clickHandler(event)"/>

<s:Button x="133" y="497" label="logout" width="106" height="28" click="logout_clickHandler(event)"/>

but dosent work could you check if wrong or right.



I test audio in the applcation and is work fine in applcation but still have one problem is logout button is dosent work i try look about event handler but will be nice if have any example about event handler for help  me to understand how i add this funcation in applcation to run logout button.

i search on intenrnet  find some example

so i typing event handler like it.

public function logout():void {

but have error:"1114: The public attribute can only be used inside a package."

any ideas

I'll give you a hint : See the docs for ConnectSessionContainer.logout();


Hi nigel,

i do and read,search about ConnectSessionContainer.logout(); and i find an example explain about it however i do the same example explain

but flash bulider say have 3 error is "1120 Access of undefined probely cSession" and here the code i add

protected function button1_clickHandler(event:MouseEvent):void
                cSession.roomURL = "" +;



Level 3


I think you have a typo.  From the code above, it looks like you named your ConnectSessionContainer "connectRoom", not "cSession":

<rtc:ConnectSessionContainer horizontalScrollPolicy="off" verticalScrollPolicy="off" id="connectRoom"


Also flash bulider give me error, jamie im try to add logout button my problem is event handler always give error in flash bulider so button logout dosent work

i need really an example explain about event handler or any help to typing the event handler im using flash bulider 4.

your code is give error in flash bulider i believe your code looks like not have realtionship with button logout im not sure.

thanks, jamie



I don't want to seem rude, but you should probably take some Flex programming classes. We can help you with LCCS questions but we can't really help you with basic programming question.

Hi Jannaahmed,

We are really trying to help you (you've got half of the LCCS team answering your questions) but you have to help yourself too.

As Raffaele said, you might want to do some additional learning on Flex & Actionscript, first, before jumping into LCCS.

The internet is full of great resources - try googling for "flex event handlers" and you will find a lot of good articles/tutorials.

For example:

The Flex documention is also a great place to spend some time at:

The LCCS Forums are meant to help developers as they build their applications and work with the platform, but there is a limit to how much we can help (we can't do all/most of the coding for you ...).

Good luck!

I believe im using flex and applcation is already created and is work fine connect with my room very well also the audio in applcation work fine too after explain from nigel about audio  i understand how is work and i test in applcation is work fine only one thing i got problem is add button to when user finish conversation and he wish go out applcation he click in button logout so leave applcation only this i need really help.
