The SRP Subclass Control is not a visible form control, although you must have at least one subclass control on a form somewhere in your application. The control acts as an interface, through which you may subclass many OI controls to gain additional functionality. Since subclassing controls depends upon the existence of the SRP Subclass Control, it is best to place this control on your most persistent window, such as the mainframe of your application.

Use the Subclass method to subclass controls and the various properties to enhance them.
