Visual Basic Programming Basics

What is a variable in Visual Basic?

• A named storage location that can hold different values during program execution.

• A constant used for mathematical calculations

• A fixed value that cannot be changed

• A function that performs a specific task

What are the different data types supported in Visual Basic?

• Integer, Long, Single, Double, Decimal, Date, String, Boolean, Object, Char, Variant

• Array

• Float

• Text

• Character

Explain the concept of control structures in Visual Basic.

• Control structures in Visual Basic are used for designing user interfaces.

• Control structures in Visual Basic are used for mathematical calculations.

• Control structures in Visual Basic are used for data storage.

• Control structures in Visual Basic are used to dictate the flow of execution in a program.

What are the types of control structures in Visual Basic?

• Linear

• Conditional

• Sequential, Selection, Repetition

• Looping

What are functions and procedures in Visual Basic?

• Functions return a value after execution, while procedures do not.

• Functions and procedures are the same thing in Visual Basic.

• Procedures return a value after execution, while functions do not.

• Functions and procedures cannot be used in Visual Basic.

Differentiate between functions and procedures in Visual Basic.

• Functions can have optional parameters, while procedures cannot have any parameters.

• Functions can be called from other modules, while procedures are limited to the module they are defined in.

• Functions return a value after execution, while procedures do not return any value.

• Functions return multiple values, while procedures return only one value.

How are forms and controls used in Visual Basic programming?

• Forms and controls are used for backend logic only in Visual Basic programming.

• Forms and controls are essential components for designing the graphical user interface (GUI) in Visual Basic applications.

• Forms and controls are only used for data storage in Visual Basic programming.

• Forms and controls have no impact on the user interface in Visual Basic programming.

Explain the role of forms in Visual Basic applications.

• Forms are only used for data storage in Visual Basic applications.

• Forms play a crucial role in defining the layout and behavior of the application's interface.

• Forms have no impact on the user interface of Visual Basic applications.

• Forms are optional components in Visual Basic applications.

What are the common controls used in Visual Basic forms?

• sliders

• buttons, textboxes, labels, checkboxes, radio buttons, listboxes, combo boxes, picture boxes

• images

• textboxes

How can you create a new form in Visual Basic?

• Go to Solution Explorer, right-click on project, select Add, then Windows Form

• Open a new project and the form will automatically be created

• Click on the Start menu and select New Form

• Use a command line prompt to generate a new form
