Gets or sets the time period, in milliseconds, that it takes the progress block to scroll across the progress bar.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
A marquee-style progress indicator does not display progress; instead it indicates that an operation is occurring by moving the progress block across the progress bar.
Since the marquee animation speed is a time period, setting the value to a higher number results in a slower speed and a lower number results in a faster speed.
The Marquee style is supported only on these platforms.
