Windows Forms ProgressBar: Easiest way to start/stop marquee?
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.
To start/stop the animation, you should do this:
To start:
progressBar1.Style = ProgressBarStyle.Marquee;
progressBar1.MarqueeAnimationSpeed = 30;
To stop:
progressBar1.Style = ProgressBarStyle.Continuous;
progressBar1.MarqueeAnimationSpeed = 0;
