Visual Basic (VB) : MCQs & PYQs with Explanation

Option B

Visual Basic (VB) is a high-level, event-driven programming language developed by Microsoft. It was designed to make Windows application development simple by providing an easy-to-understand syntax and a graphical development environment.
Visual Basic allows programmers to create applications rapidly using drag-and-drop controls such as buttons, text boxes, labels, and menus. 

• It is widely used for developing desktop applications and learning programming fundamentals.
• VB.NET is the modern version of Visual Basic and is built on the .NET Framework.

Option A

Visual Basic is an Event-Driven Programming language. In event-driven programming, program execution depends on events generated by the user or the system.
E.g.:
Private Sub Button1_Click(...) Handles Button1.Click
    MessageBox.Show("Welcome to Suraku Academy")
End Sub
The code executes only when the button is clicked.

Option B

In Visual Basic (VB), Integer Division is performed using the backward slash () operator. Integer division returns only the whole-number (integer) quotient and discards the fractional part of the result.

Arithmetic Operators in Visual Basic:

Option C

In Visual Basic (VB), controls are graphical components placed on a form to interact with the user. Different controls serve different purposes, such as displaying text, accepting user input, or providing selectable options.
A Text Box is the control used to accept input from the user as well as display text or output. Users can type data into a text box, and the program can also display calculated results or messages in the same control.

Commonly Used Visual Basic (VB) Controls:

Option B

Variables in Visual Basic are declared using the Dim keyword.

• Dim means Dimension.
• Used for local and module-level variables.

E.g.:

• Dim age As Integer
• Dim name As String

Option D

In Visual Basic (VB), controls are used to create graphical user interfaces (GUIs). Each control has a specific purpose and supports different properties and events.
A Label control is used to display text such as headings, instructions, messages, or program output. Although users cannot edit its content, the program can change its text during execution to display results.
The Image control has a Stretch property. When this property is set to True, the image automatically resizes (stretches or shrinks) to fit the dimensions of the control.
A Command Button is mainly used to perform an action when the user clicks it. Therefore, the Click event is the most frequently used event for this control.

Option B

In Visual Basic (VB), the Len() function returns the total number of characters in a string. It counts, alphabets, digits, special characters, spaces. Each character, including a space, is counted as one character.
In the given expression, Len("Visual Basic Tutorial") there are total 21 characters.

Common Visual Basic String Functions:

Option A

The source code files of Visual Basic .NET use the .vb extension.

• The .bas is for module file in classic Visual Basic.
• The .vbs is for VBScript file.
• The .exe is for executable program.

Option A

Visual Basic (VB) is a high-level, event-driven programming language and development environment developed by Microsoft.
It was designed to make Windows application development easier by allowing programmers to create Graphical User Interface (GUI) applications using a simple drag-and-drop approach.
The first version of Visual Basic (Visual Basic 1.0) was officially released by Microsoft in 1991 for the Windows operating system.

Option C

Visual Basic (VB) is an event-driven programming language developed by Microsoft for building Windows applications. Before Microsoft introduced the .NET Framework, several versions of Visual Basic were released.
The last standalone version of classic Visual Basic was Visual Basic 6.0 (VB6), released in 1998. After this, Microsoft introduced Visual Basic .NET in 2002, which was built on the .NET Framework and was significantly different from the earlier versions.
