Client UI Windows
 

Is there a place in a DB or someplace to edit what client UI windows are displayed?

Say I don't want the pet window, map window or more then 1 hot bar to be able to be displayed client side, what controls that?

The only way to limit stuff like that is by setting your server to a specific expansion like classic, which is done by adjusting the expansion field in the variables table. That then causes the client to be restricted to most of the stuff that was only available at the highest expansion you allow them access to from that variable. I think it also means they would only be able to access the content (zones, playable races/classes, etc) from that specific expansion or earlier.

Yes, got the expantion set correctly. Limits zones, models, class/race. But I have seen on some servers where they can actualy control what windows are allowed client side. I was just wondering how they do that. A good example of that is on Project 1999's server were they have disabled like the map window and I think a few other windows. That is so cool how they do that. Thought maybe there was a setting server side that controls that. Or maybe they probably hard code it some how. (hoping more for the possible DB setting or something easier since I don't know how to write code)

Project 1999 modifies the client using DLL injection. Since you've said you're not a coder I'm going to say that something like that is out of your depth.
