Access Tutorial 12: An Introduction to Visual Basic
12.1Introduction: Learning the
basics of programming
Programming can be an enormously complex and
difficult activity. Or it can be quite straightforward. In
either case, the basic programming concepts remain
the same. This tutorial is an introduction to a handful
of programming constructs that apply to any "third
generation" language, not only Visual Basic for
Applications (VBA).
Strictly speaking, the language that is
included with Access is not Visual Basic—it is
a subset of the full, stand-alone Visual Basic
language (which Microsoft sells separately).
In Access version 2.0, the subset is called
"Access Basic". In version 7.0, it is slightly
enlarged subset called "Visual Basic for Applications"
(VBA). However, in the context of the
simple programs we are writing here, these
terms are interchangeable.
12.1.1Interacting with the interpreter
Access provides two ways of interacting with the
VBA language. The most useful of these is through
saved modules that contain VBA procedures. These
procedures (subroutines and functions) can be run to
do interesting things like process transactions
against master tables, provide sophisticated error
checking, and so on.
The second way to interact with VBA is directly
through the interpreter. Interpreted languages are
easier to experiment with since you can invoke the
interpreter at any time, type in a command, and
watch it execute. In the first part of this tutorial, you
are going to invoke Access VBA interpreter and execute
some very simple statements.
