ActiveUp has some interesting controls, demos are
here.
Some of the more interesting ones were a "Page Loading" control, which takes over the screen while a page is downloading until the page has finished. This is pretty nice, and I could seem some use for it on some of our pages that do a lot of processing, or send down a lot of data in the form of a long grid or whatever.
Also, they have a
page protector control, which basically disables the ability to copy and past from the page. Also, it take the content of the page, encodes it and sends down a javascript write command, so I guess if you looked at the source it would be a long encoded string. This would really discourage the avg person, but it wouldn't be hard to convert the string back your self.
Still, pretty neat.
