Structure of a Visual Basic Application

• 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.
