6.1. Overview

Properties are a set of variables available in each instance of an Active-X Control (OCX). The majority of these variables allow the programmer to set or access their value, some of them are read only. Each assignment as well as each reference of property variables are controlled by underlying program code within the OCX. Most of the properties are available at design time. This allows the OCX user to set or change initial values without having to write code. Another advantage is, that the OCX logic ensures, that the values read form properties are always valid.
