Progress bar controls now support control styles. You can set progress bar styles in the same way as other common controls (CreateWindowEx,GetWindowLong,SetWindowLong). The following are the supported styles:
PBS_SMOOTH Version 4.70. The progress bar displays progress status in a smooth scrolling bar instead of the default segmented bar.
PBS_VERTICAL Version 4.70. The progress bar displays progress status vertically, from bottom to top.
