Course Overview With over two million users, Microsoft Visual Basic is by far the most popular Windows development environment in use in major organisations today. This course will provide you with a comprehensive coverage of the Visual Basic programming environment. It is an intensive course which has been structured to cover the maximum material in four days, with around half the time spent on practical hands-on exercises. Detailed language constructions are learnt by delegates during practical sessions and the comprehensive approach saves time for the development of the more important conceptual areas. This course recognises the importance of coding for reuse and uses an object approach throughout. Emphasis is also given to the database connectivity features of Visual Basic; in particular, the use of ActiveX Data Objects (ADO) to manipulate databases through dedicated controls or purely through code.! The course is made up of a mixture of lectures and hands-on exercises. It includes many practical sessions designed to reinforce the topics covered. You will build a full Visual Basic application during the course. Course Outline Quick Start - Design environment
