I'm hoping someone can help me.  The only information (aside from the
limited MSDN help) seems to reference older technology/methods which
I'd like to stay away from.

VS 2005 (.net 2.0) has a ProgressBar with Marquee mode.  This mode
confuses the H out of me.  I fully understand how the 'normal' modes
of the progress bar work, with .increment or .performstep methods.
With those methods, I actively control the progress bar's value.

I don't understand marquee mode apparently.  As soon as I set it to
marquee mode, it starts scrolling???  There's no form of a stop/start
method for this style??  So far I've resorted to starting the progress
bar in "block" mode, and change it to 'marquee' mode right before I do
something requiring the use of a progress bar and then changing it
back to 'block' mode when done with it.  Is this my only option??

I could live with that option if I were dealing with a single threaded
app, but I'm having a difficult time using this method when using a
backgroundworker component.

Before I call the "RunWorkerAsync" method, I change my progress bar to
'marquee'.  In the "RunWorkerCompleted" method I then change it back
to 'block' mode.  When using this method, since I'm not actively
"incrementing" the progress bar, there seems to be no use for the
'progresschanged' event of the background worker itself.

While the above seems to "work" ok, this is not an ideal solution.
I'm fully managing the progress bar from the UI thread.  With this
solution I'm not monitoring progress on the backgroundworker thread at
all.  I'm merely monitoring progress on the UI thread in hopes the
background thread returns successfully.  If the backgroundworker
thread froze up for any reason to where it couldn't complete, I
wouldn't know since the progress bar would still be churning away
fooling the user into thinking the app is still "trying" to process
the data.

I need to monitor the background thread itself, but can't seem to find
a way to get marquee mode to work since I can't effectively utilize
the backgroundworkers 'progresschanged' event.

Is there an elegant solution for this?
