I want to go on the profile of a member connected to him and sent an instant message.
How can I integrate FreichatPure into "Profile pro"?
Thank you for your help.

Are you talking about the

"Community Builder Profile Pro"

It wont be easy to do that, i may be able to help you in freichat's code but i cannot integrate it because
development for FreiChatPure is stopped and also i will have to study CB code for that.
which is not possible at the moment

This is because FreiChatX a new CMS independent version is being developed

How can you help me?

If you are a programmer and if you want to integrate freichat yourself,

then i may be able help you in the changes required in freichat's code

I would like to know what code to display a single member in line, that I visit.

rather than go around all connected, only that I visit

$ses=$session->getId();

$db->setQuery("SELECT * FROM #__session WHERE session_id='$ses'");
$is = $db->loadAssocList();
foreach($is as $set)
{
$_SESSION["fromname"]=$set["username"];
$_SESSION["userid"]=$set["userid"];
}
}

I find a solution but i want to know if you can hide the module without disabling.
Thank you

you can use firebug to find the div that you want to hide.
then you an simply use the javascript code

$jn('#divname').hide();

why don't you use FreiChatX, it is much faster and a lot of bugs have been resolved.
you can configure FreiChatX to provide exact same functionality as FreiChatPure.
I dont think there is any reason not to upgrade!
