  1. SCOPE Visual Basic Hands-on Training

  2. Objectives • Understand what is a program • Understand what programming is • Understand the program development life cycle • Create a Visual Basic 2005 Windows Application project Chapter 2: Program and Graphical User Interface Design

  3. What is a Computer Program? A set of instructions that tells the computer hardware how to obtain input, what action to perform, and the output to produce. Chapter 2: Program and Graphical User Interface Design

  4. What Programs Do • Input Data (Values) • Process (Calculations) • Output Results (Information) Chapter 2: Program and Graphical User Interface Design

  5. What is a Developer? One who develops a program (application) by writing the instructions (code) to produce a desired results, also referred to as a software engineer or computer programmer. Chapter 2: Program and Graphical User Interface Design

  6. Program Development Life Cycle • Set of phases and steps that are followed by developers to design, create, and maintain a computer program • Gather and Analyze the Program Requirements • Design the User Interface • Design the Program Processing Objects • Code the Program • Test the Program • Document the Program/System • Deploy the Program/System • Maintain the Program/System Chapter 2: Program and Graphical User Interface Design

  7. Phase I: Gather and Analyze the Program Requirements • Gather project requirements by interviewing users, reviewing current procedures, and completing other fact-gathering tasks • Two types of requirements documentation • Requirements document • Use Case Definition or OIP Chapter 2: Program and Graphical User Interface Design

  8. Chapter 2: Program and Graphical User Interface Design

  9. Chapter 2: Program and Graphical User Interface Design

  10. OIP Form Chapter 2: Program and Graphical User Interface Design

  11. Phase 2: Design the User Interface • Developers sometimes spend 25% to 40% of the program design time on the user interface • Presentation layer • Use Visual Studio to create the user interface • Interface designs are often called mock-ups Chapter 2: Program and Graphical User Interface Design

  12. Problem Definition • You are to create a hotel room selection program. Chapter 2: Program and Graphical User Interface Design

  13. Phase 3 – Design the Program Chapter 2: Program and Graphical User Interface Design

  14. OEA Form (1) Chapter 2: Program and Graphical User Interface Design

  15. OEA Form (2) Chapter 2: Program and Graphical User Interface Design

  16. Phase 4/5 – Code and Test the Program • After the events and tasks within the events have been identified, the developer is ready to code the program • Entering Visual Basic statements to accomplish the tasks specified on the event planning document • Developer enters the code and implements the logic Chapter 2: Program and Graphical User Interface Design
