Course Objectives

This course provides students with a basic practical knowledge of application development using Visual Basic. It teaches both project design and construction, while covering the syntax of the language in detail. During the course the student will write many applications to ensure that the concepts and statements taught are fully understood and practical experience is gained. On completion of this course the student will be able to:

    use the major concepts of a modern language, such as control flow, function calls and modular programming.
    use windows forms and all the components available to them.
    use the visual basic IDE to layout and build applications.
    use and understand many of the built in functions available to VB.

Course Format

Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will build a simple but complete application. Examples are used extensively, ranging from simple code 'snippets' to full applications with complete ‘real world’ functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and ‘experiment’ with these under the instructor’s guidance as they are introduced. These examples are available to take away, along with the delegate’s own work. The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
