VISUAL BASIC – CHAPTER ONE NOTES An Introduction to Visual Basic VISUAL BASIC – CHAPTER ONE NOTES An Introduction to Visual Basic .NET and Program Design INTRODUCTION A ___________________________________ is a step-by-step series of instructions. ____________________________________________ is the process of writing these instructions. ____________________________________, or ___________________________________________, design and write programs. An __________________________________ is a collection of one or more programs. _____________________________________________________ is the process of writing applications. WHAT IS MICROSOFT VISUAL BASIC .NET? ____________________________ is a programming environment that allows you to build programs for the Windows operating system or any system that supports Microsoft’s .NET architecture VB.NET is based on the ____________________________________________________________. Evolved from BASIC (Beginner’s All-purpose Symbolic Instruction Code PROGRAMMING AND APPLICATION DEVELOPMENT _________________________________ _________________________________: -- This is how a computer processes information and it consists of four basic steps: ___________________________________________________________ APPLICATION TYPES – WHAT KIND OF THINGS CAN YOU MAKE WITH VB.NET? _______________________ THE DEVELOPMENT CYCLE – HOW DO YOU CREATE A PROGRAM? Phase 1 – ____________________________________________ Verify the requirements are complete Make the initial determination that it is possible to solve the problem using a program List _______________________and _____________________ data required Determine whether the input data is available for testing Ensure that the information provided explains how to convert the input data into output data so that a solution, or algorithm, can be developed

VISUAL BASIC – CHAPTER ONE NOTES An Introduction to Visual Basic VISUAL BASIC – CHAPTER ONE NOTES An Introduction to Visual Basic .NET and Program Design Phase 2 – _____________________________________ Develop a logical model that illustrates the sequence of steps you will take to solve the problem __________________________ are smaller pieces of a program _________________________ – illustrates the attributes and methods of an object ______________________ -- values that determine, for example, the appearance of an object. ______________________ -- instructions the object uses to generate output or perform actions. ___________________________ graphically represent the logic used to develop an algorithm _____________________________, included in flowcharts, allow the programmer to specify the code that will execute only if a condition is met _____________________________ expresses the step-by-step instructions using keywords and depicts logical groupings or structures using indentation Phase 3 – ______________________________________ Validate, or check, the program design Step through the solution with test data Compare the program design with the original requirements Phase 4 – ______________________________________ Write the code that translates the design into a program Create the user interface Create comments, or notes, within the code that explains the purpose of the code Test the code as it is written THIS IS WHERE IT GETS FUN! You tried to write a program … does it work? Does it do what you wanted it to do? Is it user-friendly? Phase 5 – ______________________________________ Test plan Test cases Make sure to set boundary values Phase 6 – ______________________________________ Includes the requirements documents, program design documents, user interface documents, and documentation of the code Code should be archived electronically OBJECT-ORIENTED PROGRAMMING AND OBJECT-ORIENTED DESIGN _________________________________________________________ Data and the code that operates on the data are packaged into a single unit called an object Represents the logical plan of a program as a set of interactions among objects and operations
