PowerBuilder (Basic)

These concepts cover PowerBuilder's fundamental syntax and basic features. They are necessary for writing simple PowerBuilder programs and understanding the core structure and flow of PowerBuilder applications.

  1. Introduction to PowerBuilder
    • PowerBuilder’s role in app development, setting up IDE/SDK, and understanding its application significance.
    • PowerBuilder’s key concepts and terminology, and review different versions and their unique features
    • Reason: Familiarizing yourself with the development environment is essential for initiating PowerBuilder projects efficiently.
    • Example Task: Configure a new PowerBuilder project and develop a basic "Hello, World!" application.
  2. Setting Up Workspaces, Targets, and Application Objects
    • Configure workspaces and targets for organized PowerBuilder projects, ensuring structured development, testing, and deployment.
    • Create and configure application objects like windows and menus for a functional PowerBuilder app.
    • Reason: Setting up workspaces, applications, and targets helps streamline the development process and manage different project configurations.
    • Example Task: Create a workspace, set up a target for a sample application, and establish basic application objects within the workspace.
  3. Connecting to a Data Source Using Database Profiles
    • Learn to create database profiles to establish connections between PowerBuilder and various database systems.
    • Gain the skills to verify database connections and troubleshoot any connection issues to ensure data can be retrieved or updated.
    • Learn about control structures such as loops and conditional statements to control the flow of your PowerBuilder scripts: A database profile is crucial for enabling data access and interaction within PowerBuilder applications.
    • Example Task: Set up a database profile for a sample database and test the connection to ensure successful interaction.
  4. Employing Basic Programming Techniques
    • Explore how to declare and use variables and data types in PowerBuilder scripts to handle different kinds of data.
    • Learn about control structures such as loops and conditional statements to control the flow of your PowerBuilder scripts.
    • Reason: Understanding variables and data types is fundamental for effective data manipulation and application storage.
    • Example Task: Declare variables of different types and perform arithmetic operations to see how they work in practice.
  5. Writing Code Using Basic Coding Techniques
    • Understand how to define methods for modular programming and call them from different parts of your code to perform specific tasks.
    • Learn to define and use global variables and functions that can be accessed from various parts of your application.
    • Reason: Methods help encapsulate functionality and promote code reuse and organization.
    • Example Task: Define a global variable, create a method to calculate the sum of two numbers and call this method from the main script.
  6. Creating and Using a Framework
    • Learn to create framework windows that define your application's overall layout and structure, including common elements like menus and toolbars.
    • Explore how to customize and extend framework windows to meet specific application requirements and improve functionality.
    • Reason: Framework windows provide a consistent look and feel across the application, enhancing user experience.
    • Example Task: Set up a framework window with a menu and status bar and configure its layout and properties.
  7. Creating and Using Standard Visual Objects
    • Learn to add and configure standard visual controls like buttons, text boxes, and labels on your windows to create interactive user interfaces.
    • Understand how to use configuration files to manage application settings and preferences, ensuring that configurations can be adjusted without modifying the code.
    • Reason: Visual controls are essential for building user interfaces that users interact with directly.
    • Example Task: Add a button and a text box to a window and configure their properties to align with the application’s design.
