What do you call a looping progress bar?

Question

Ok I'm just at a loss for what the correct terminology is for this. I'm looking for the correct name to call a progress bar that "loops". Instead of the standard progress bar that fills up from left to right to 100%, this looks exactly like the progress bar but a small portion of the fill color constantly loops, never filling the whole progress bar to 100%, basically making it an eternal progress bar similar to a Ajax loading image. Microsoft likes to use this progress bar in their dialogs now.

What do you call this thing so I can search for some controls, etc.? Does .Net have a control for this?

Thanks

Answer 1

Indeterminate progress bar?

Java's JProgressBar specifically refers to "Indeterminate mode"

Answer 2

I've always known a busy indicator that doesn't indicate relative progress as a "spinner". It may be a bar in this case, but it's the same thing.
