I just completed Vbar, a new class that draws vertical ProgressBars. It uses the same properties as a regular ProgressBar : Value and Maximum.
Besides being vertical, it also adds variable width, so the bar can be made larger, as you can see above. It is also platform sensitive, and produces Mac style or Windows style bars depending on where it runs. Under Linux, Windows style is used.
Download a zip containing the class and a sample project here.
Hope you enjoy it.
