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.
Windows XP Home Edition, Windows XP Professional x64 Edition, Windows Server 2003 Platform Note:
The Marquee style is only supported only on these platforms.
