That's actually been part of all flashchat 4.x.x releases, and something I've always used. Someone mentioned it the other week and I realised that perhaps most people were not aware of it, so I decided to add it to the instructions when I next updated them. :)

i'm in the process of a fresh vB install, including the 4.7 FC - is this hack current to coincide with the recent release of FC?

It showing the flashchat inside forum, but in a new window, what to do for not open a new window and open the chat in the same where user clicks on the chat link?

I've replaced that

with that
and tried too _self by replacing _parent

Not exactly sure what you mean by that, but I'm running 4.7.0 on my site(s).

That code has nothing to do with it opening in a new window, you need to change back what you altered. How it opens depends on the link you created for it.

Thanks for your fast reply,
The link that I have create is:
Have to change the target?

EDIT,
yes, just modify the target with _parent and works in the same window.

Is there anyway to resize chat screen as in the same window with vbulletin header and footer?

If I understand what you are asking...Go into your admin panel, vBulletin Options, General Settings, scroll all the way to the bottom and you'll see "FlashChat Height". The default is 600, I *much* prefer 500.

NeitherSparky, Yes you have understanding fine, Thank you :)
GREAT PRODUCT! Thanks for sharing

Maybe I've overlooked this, but I have a small problem.

When a person who isn't logged into my forums goes to chat, it prompts them to log in, they can enter there username and pass and log right into chat, however this doesn't log them into the forums, so they only show up in chat.

How do I make it so that if you're not logged into the forums, you either don't get a flashchat login screen, or if you DO login to flashchat, it logs you into the forums?

You have not integrated Flashchat properly with vbulletin. You need to make sure the vbulletin36CMS is specified as your CMS system in Flashchat's config file.
