Visual Basic Foundation

Description:

This course provides an introduction to programming in Visual Basic. The course uses a workshop approach, illustrating key features with practical hands-on examples. Participants will gain experience in manipulating objects in an event-driven environment and at the end of the course will be able to develop user-friendly Windows applications.

Pre-requisites:

The course assumes that participants are familiar with Microsoft Windows. Participants should also understand basic programming concepts, either through using formal programming languages or writing macros.
