• Summary

For many developers, the ability to easily create ActiveX controls is one of the most compelling features Delphi brings to the table. ActiveX is a standard for programming language-independent controls that can function in a variety of environments, including Delphi, C++Builder, Visual Basic, and Internet Explorer. These controls can be as simple as a static text control or as complex as a fully functional spreadsheet or word processor. Traditionally, ActiveX controls are quite complicated and difficult to write, but Delphi brings ActiveX control creation to the masses by allowing you to convert a relatively easy-to-create VCL component or form into an ActiveX control.
