3 Day Course

Overview

Students will learn how to use Visual Basic 5.0 to create ActiveX controls for deployment in ActiveX-capable container applications Visual Basic, Internet Explorer, Excel, PowerPoint, Visual C++, and so on.

Prerequisites

Visual Basic 5.0 Introduction or equivalent knowledge.

Benefits

Students will learn how to identify the "big picture" of ActiveX technologies and ActiveX controls; design professional-quality ActiveX controls; add properties and property persistence to ActiveX controls; add methods and events to ActiveX controls; code, test, and debug ActiveX controls; add finishing touches to ActiveX controls; compile and run ActiveX controls; distribute ActiveX controls; and create ActiveX controls for the Web.
