Windows Forms ProgressBar Easiest way to start stop marquee

Question

I am using C  and Windows Forms  I have a normal progress bar working fine in the program  but now I have another operation where the duration cannot be easily calculated  I would like to display a progress bar but don t know the best way to start stop the scrolling marquee  I was hoping for something as simple as setting the marquee speed and then having a start   and stop   but it doesn t appear to be that simple  Do I have to run an empty loop in the background  How do I best do this  Thanks

There s a nice article with code on this topic on MSDN   I m assuming that setting the Style property to ProgressBarStyle Marquee is not appropriate  or is that what you are trying to control   -- I don t think it is possible to stop start this animation although you can control the speed as  Paul indicates

Many good answers here already  although you also need to keep in mind that if you are doing long-running processing on the UI thread  generally a bad idea   then you won t see the marquee moving either

Use a progress bar with the style set to Marquee  This represents an indeterminate progress bar   myProgressBar Style   ProgressBarStyle Marquee    You can also use the MarqueeAnimationSpeed property to set how long it will take the little block of color to animate across your progress bar
