Microsoft’s Visual Basic is an object-oriented programming language. Creating type-safe.NET programmes is quick and straightforward using Visual Basic. Microsoft’s Visual Basic programming language is a development of the BASIC programming language that is meant to be used with an Integrated Development Environment (IDE) (IDE). Programming languages like BASIC relied significantly on the DOS command-line prior to the emergence of IDEs. Visual Basic provides a simple way to create user interfaces. For efficiency, Visual Basic can communicate with C code. Visual Basic is not a powerful programming language that allows you to accomplish anything. Visual Basic isn’t very beautiful or quick. Visual Basic is not a substitute for C.
Uses of Visual Basic:
- User Interface Design – (designing UI for applications etc)
- Using the Standard Controls in Visual Basic – (designing and Developing using its easy Drag-and-Drop IDE for faster and easier development)
- Object-Oriented Programming
- Debugging and error handling in your code – (VB also works as a debugger for other programs, if a programme runs into an error, we can use VB to Debug the program)
- Managing Files, Folders, and Drives – (Same as Programming with Objects).
- Create graphical windows, dialogue boxes, and menus for your apps.
- Create database-friendly apps.
- Create Internet-based apps and Web-based applications.
- Create graphics-based apps.
Visual Basic Controls
Visual Basic provides a wide assortment of controls for gathering input, displaying information, selecting values, showing graphics, and more. Table below lists some of the commonly used controls.
Control Type | Description |
CheckBox | A box that is checked or unchecked when clicked with the mouse |
ComboBox | A control that is the combination of a ListBox and a TextBox |
Button | A rectangular button-shaped object that performs an action when clicked with the mouse |
Form | A window, onto which other control can be displayed |
GroupBox | A rectangular border that functions as a container for other controls |
HScrollBar | A horizontal scroll bar that, when moved with the mouse, increases or decreases a value |
Label | A box that displays text that cannot be changed or entered by the user |
ListBox | A box containing a list of items |
RadioButton | A round button that is either selected or deselected when clicked with the mouse A control that displays a graphic image |
PictureBox | A control that displays a graphic image |
TextBox | A rectangular area in which the user can enter text, or the program can display text |
VScrollBar | A vertical scroll bar that, when moved with the mouse, increases or decreases a value |
Working Environment:
Many elements make up visual basic’s working environment:
- The title bar displays the programme title, project name, and programme mode.
- The menu bar is where you’ll find the menus and commands that go with them.
- The tool bar is made up of icons that are shortcuts to commonly used commands. Standard, formatting, and other toolbars are examples.
- Toolbox: A toolbox with controls displays on the left side of the screen.
- The form designer appears in the centre of the screen, where the graphical user interface elements (controls) are shown.
- The properties window allows us to change the properties of controls.
- The project explorer pane shows the files that make up the project.
- The layout pane shows the form-icon, which is used to establish the form’s start-up position.
- Immediate window: may be used to test any statement or print the value of a variable.
What are the various VB programming modes?
A VB programme can be run in three modes:
design: (when creating a form or coding).
When a programme is running, it is said to be in run mode.
When a programme is in break mode, it is said to be in break mode.
Visual Basic file:
A VB file is a project item file written in the Visual Basic language, a Microsoft-developed object-oriented programming language for use with the.NET Framework. It provides ASCII text instructions in Visual Basic.
Visual Basic source code files are most typically associated with files having the .vb suffix. Microsoft’s Visual Basic programming language is supported by their development tool Visual Studio. Programmers use Visual Studio to develop Visual Basic code and turn it into executable apps.
Visual Basic for Applications (VBA)
It is a component of Microsoft Corporation’s (NASDAQ: MSFT) heritage Visual Basic software, which was created to aid in the development of Windows programmes. Microsoft Office (MS Office, Office) applications such as Access, Excel, PowerPoint, Publisher, Word, and Visio use Visual Basic for Applications as an internal programming language.
TAKEAWAYS IMPORTANT
- Visual Basic for Applications is a Microsoft-developed and-owned programming language.
- You may use VBA to construct macros to automate repetitive word and data processing tasks, as well as to create custom forms, graphs, and reports.
- VBA is a component of Microsoft Office; it is not a standalone product.
Conclusion:
Visual Basic contains a number of visual tools that may be used to construct sophisticated applications with a more complex user interface. As a result, Visual Basic is more than just a programming language. It also comes with a number of libraries that may be used to create object-oriented programmes. Typically, programmes entail big development teams working on many projects at the same time.
