Form Status Controls Stop Updating if Form Loses Focus

I have created an .NET 2.0 application that does a lot of data processing.
When the user starts the process there are a couple of progress bars and the
status strip that are updated as the code executes to give feedback on the
process.

It all works as planned UNLESS the user does something to take the focus
away from the form, such as moving the form or working in another application.

I know that the desired result is possible because you see it all the time
in things like install packages. What do I need to do to force the form to
update itself? this.Refresh() does not make it happen if the form loses
focus.
 
I bet you're using a timer to update with...

Try using System.Timers.Timer. It's independent of the Forms message pump
and so will fire even when the form is not pumping messages.

Remember that the timer fires on another thread so you have to invoke a
method on the UI thread from the timer handler otherwise you'll get
problems.
