About Controls

ATEasy controls are based on the Microsoft ActiveX/OCX control technology as the standard. Their properties can be set using the ATEasy property window. Using the ATEasy programming language, the properties can be changed, methods can be called, and event procedures can be written.

The following is a list of the ATEasy controls:
