| | Core Focus | Typical Practical Exercises | | :--- | :--- | :--- | | 1. Getting Started & The IDE | Navigating the Visual Basic 6.0 Integrated Development Environment (IDE). | Creating a new "Standard EXE" project; saving projects correctly; using the Toolbox, Properties window, and Form Layout window. | | 2. Basic Controls & Properties | Using fundamental UI elements like buttons, text boxes, and labels. | Changing caption properties; designing a simple user interface; creating a "Hello World" message box or a program that displays your name after clicking a button. | | 3. Variables, Data Types & Operators | Storing and manipulating data in memory. | Declaring variables (e.g., Dim a, b, c As Integer ); performing arithmetic operations (addition, subtraction); building a simple calculator. | | 4. Control Structures (Logic) | Directing the flow of a program's execution using conditions and loops. | Using If...Then...Else for decision-making (e.g., checking if an exam grade is passing); using For...Next loops to iterate through numbers; calculating squares of input values. | | 5. Working with Collections | Managing lists of data and creating interactive menus. | Populating, adding to, and removing items from ListBox and ComboBox controls; creating drop-down menus with Select Case statements for multiple options (e.g., a currency converter). | | 6. Functions & Procedures | Writing reusable blocks of code to improve organization. | Creating a function to calculate the cube of a number; building a Sub procedure to clear all input fields on a form. | | 7. Graphics and Multimedia | Drawing shapes, handling images, and even playing sounds. | Using the Line and Circle methods to draw shapes; using the Pset method to plot mathematical functions; creating simple animation with the Timer control. | | 8. Debugging and Error Handling | Finding and fixing bugs in your code to make it robust. | Using breakpoints to pause execution and inspect variable values; stepping through code line by line; implementing On Error statements to manage unexpected issues (e.g., division by zero). | | 9. File and Database Operations | Reading and writing data to files and connecting to a database for persistent storage. | Creating simple text files to save user data; building a program to connect to a Microsoft Access database using the Data Control or ADO (ActiveX Data Objects) to add, update, and delete records. | visual basic 6.0 practical exercises pdf
