1. Introduction to the Visual Basic Language and Environment
Structure of a Visual Basic Application
Application (Project) is made up of:
Forms - Windows that you create for user interface
Controls - Graphical features drawn on forms to allow user interaction
(text boxes, labels, scroll bars, command buttons, etc.) (Forms and
Controls are objects.)
Properties - Every characteristic of a form or control is specified
by a property. Example properties include names, captions, size, color,
position, and contents. Visual Basic applies default properties. You can
change properties at design time or run time.
Methods - Built-in procedure that can be invoked to impart some
action to a particular object.
Event Procedures - Code related to some object. This is the code
that is executed when a certain event occurs.
General Procedures - Code not related to objects. This code must
be invoked by the application.
Modules - Collection of general procedures, variable declarations,
and constant definitions used by application.
