A spin button consists of at least one spin field that is a single-line entry (SLE) field, and up and down arrows that are stacked on top of one another. These arrows are positioned to the right of the SLE field.
You can create multi-field spin buttons for those applications in which users must select more than one value. For example, in setting a date, the spin button control can provide individual fields for setting the month, day, and year. The first spin field in the spin button could contain a list of months; the second, a list of numbers; and the third, a list of years.
The application uses a multi-field spin button by creating one master component that contains a spin field and the spin arrows, and servant components that contain only spin fields. The spin buttons are created at component initialization. The servant components are passed a handle to the master component in a message. When a servant spin field has the focus, it is spun by the arrows in the master component.
The list of values in a spin button entry field can be an array of data or a list of consecutive integers, defined by an upper and a lower limit.
