Description

This is the second course in a five part series that will provide students with the skills to write a Microsoft Visual Basic-based application that accesses data from a database. In this course, students will learn to use class modules to define and create an instance of a component. Students will also be provided with the basic instruction on the ActiveX Controls feature of Visual Basic 6.0.

Audience

This course is designed for programmers who need to create basic applications with Microsoft Visual Basic 6.0. Participants should have completed the first course in this series.
