Visual Basic is a programming system developed by Microsoft that allows users to create graphical user interface applications for Windows using an event-driven programming language based on BASIC. It provides tools and objects for building forms, using controls and handling events, as well as features for database access, debugging, and distributing applications. Newer versions of Visual Basic introduced improvements like faster compilers, additional database and internet capabilities.
Introduction to visual basic 6 (1)
- 2. It's a computer programming system developed and owned by Microsoft. It is a tool that allows you to develop Windows (Graphical User Interface-GUI) applications. It is event-driven, meaning code remains idle until called upon to respond to some event (button pressing, menu selection,……) The basis of Visual Basic is an earlier programming language called BASIC (Beginner’s All-Purpose Symbolic Instruction Code).
- 3. Full set of objects –you ‘draw’ the application Lots of icons and pictures for your use Response to mouse and keyboard actions Clipboard and printer access Full array of mathematical, string handling, and graphics functions Can handle fixed and dynamic variable and control arrays Sequential and random access file support
- 4. Useful debugger and error-handling facilities Powerful database access tools ActiveX support Package & Deployment Wizard makes distributing your applications
- 5. Faster complier New ActiveX data control object Allows database integration with wide variety of applications New data report designer New Package & Deployment Wizard Additional internet capabilities
- 6. Click on these tab if you want to creating new programs To open existing program you can click these tab These tab will hold list of previously open and created project
- 7. This is place where you will work. Menu Bar Tool Bar Project Explorer Tool Box Properties Form Window
- 8. Menu Bar – a list of choices of command that you can use to control the VB Environment. Tool Bar – a collections of button that provides shortcuts or easy access to the different command on the Menu Bar.
- 9. Form- contains control, and it’s actions are defined by the code.
- 10. Project Explorer Window - a tree-structured view of all files inserted into the application View Code Toggle Folders View Objects
- 11. The Project Explorer Window is compose of three buttons: 1. View Code -were you write the different programming statements you use in VB 2. View Objects - were you can continue designing your FORM for the different user interface you will be creating 3. Toggle Folders- represents the grouping of the different forms and module in your project
- 12. Properties of Window – list all the properties a control has and their value
- 13. Form Layout Window – used to position or arranged in all different Form on your computer screen
- 14. Toolbox –consists of all the controls essentials for developing in Visual Basic Application.
- 15. These are used so you can calculate and assign expression results to variables when you code assignment statements that contain expressions. Operator Example Description + Net +Disc Adds two values - Price-4.00 Subtracts one value from another value * Total*Fact Multiplies two values / Tax/Adjust Divides one value by another value ^ Adjust^3 Raises a value to a power & (or +) Name 1 & Name 2 Concatenates two strings
- 16. Operators Order of precedence () Values inside the parenthesis are always evaluated first ^ Exponentiation - Negation is third */ Multiplication and division are fourth Division is fifth Mod Remainder is sixth +- Addition and Subtraction are last
