A slider control is used to show the progress of a process. Progress is represented by a series of bars. Each bar is a slider control. A slider control may be interactive or display only. To program a slider control, use the IASSlider interface, which contains methods, such as get_Incr and put_Incr, to specify the value of the slider increments.
The following illustration shows a slider control used to set frequency levels in the graphic equalizer.
