Creating the Circle Control
Circle: ActiveX Control, Lesson 1
Tip If you prefer working from a printed tutorial, see in MSDN Library Help for details about printing a lesson, a set of topics, or a single topic.
An "ActiveX control" (formerly called an OLE control) is a component object with an interface that lets it behave like a control for Windows.
In this tutorial you will create a simple ActiveX control called Circle. The Circle control demonstrates most of the features of an ActiveX control, such as properties, events, property pages, and data binding.
For a guide to the whole process of building your ActiveX control, see the next topic, The Tutorial Example: Circle. That topic shows the progression of lessons in the ActiveX control tutorial and will help you find specific parts of the task of building an ActiveX control.
