Visual Basic: Introduction

SquareOne is among the UK's leading providers of IT training to businesses of all shapes and sizes. Our company pledge is to deliver inspiring, motivational and cost effective training which brings about tangible improvements in productivity.

Through our training courses, individuals are able to gain lifelong skills and realize their full potential while clients achieve their corporate goals.

Course Objectives

In this course, you will learn to use Visual Studio to explore the Visual Basic language. The course starts with a quick overview of the .NET platform, examining assemblies, Microsoft Intermediate Language, Visual Studio profiles, XML comments, IntelliSense, and debugging.

From there, you will learn all the language features that you must internalize in order to create full-featured Web or Windows applications that make best use of the .NET platform.

You'll learn about data types, variables, and operators, along with all the important flow control structures. You'll work through several examples demonstrating the power of the .NET Framework, and dig into creating and consuming your own classes and objects.

The course moves on to working with data structures, such as arrays and collection classes, before finishing up with discussions of generics, handling exceptions and working with delegates and events.

By the end of this course, you will understand the important basic concepts that will allow you to start creating the applications you need.
