Programming: An Introduction using VBA (2 day)

About this class

Many people find that they need to be able to do a little customisation of Microsoft Office applications, such as Excel and Access, to make them work optimally in their environment; others may wish to become "fully-blown" Visual Basic developers. we have a range of courses available to assist with acquiring the knowledge and skills, however experience has shown that "you cannot make a programmer overnight" and this short course has been designed to introduce programming fundamentals, as a lead-in to those other courses. This course introduces the process of specifying and designing programs, then looks in a very practical way at the features of the "Visual Basic for Applications" (VBA) language.

Those attending will learn how to write simple, self-contained programs using various aspects of the language, and also how to call one program from another. The course uses the Visual Basic editor built-in to Excel, as this is commonly available at work or at home but please note that the course does NOT look at any Excel-specific programming features. The instructor-led course will use a mixture of lecture material and practicals, some of which will be paper-based but mostly involve writing small programs at the computer.
