Class access modifiers (CAM) are keywords that are used to specify the declared ACCESSIBILITY of the member or an OBJECT of a class. There are five types of modifiers:

• Public
• Protected

In VB.Net, there are two TYPES of events - Mouse events and KEYBOARD events. Mouse events happen through the actions, such as mouse MOVE and CLICK, on a form. These are mouse events in VB.Net:

• MouseEnter
• MouseUp
• MouseDown
• MouseWheel
• MouseHover
• MouseLeave
• MouseMove

In VB.Net, Redim is used for changing the size, modifying or manipulating an ARRAY that has already been declared. This functionality can ALSO help the developers add or FREE up elements for a COLLECTION. We can help you prepare for visual basic exam questions and answers by EDUCATING you in-depth about this language.

DATA validation is a process for ensuring that the data provided to a program by a user's INPUT or a file is of CORRECT TYPE and format.

The different examples of Data Validation include CODE Checking, Data Type Validation, Complex Validation, and Range Checking.

Each object in VB.Net is defined by the class. A class can act as a DATA type and describe the variables, procedures, and properties of any given object. As we KNOW, objects are just instances of different classes; and it is possible to create as many objects as we want once we have defined a class. In short, a Class is a COLLECTION of different objects of similar types.

MODULE MyCLASSBOX
    Class Area
        Public HEIGHT As Double 'This is Height of a box'
    End Class

It is a dialog box that displays INFORMATION related to the application to the user. However, unlike a regular form, a user cannot TYPE any text in the MESSAGE box. To support the message box feature, VB.Net PROVIDES a MSGBOX function.

Many candidates were asked about the elements in the latest versions during vb net interview questions.

Global Assembly CACHE (GAC) stores assemblies that are specifically REQUIRED for sharing by multiple applications on a computer. GAC is often used when the either.NET assembly has a UNIQUE security requirement, or if .Net applications have to be SHARED with other applications.

There are three TYPES of AUTHENTICATION in VB.Net - Windows Authentication, Forms Authentication, and Passport Authentication.

AUTHENTICATION REFERS to identifying an entity. Authorization refers to granting or denying access, depending on the DEFINED access rights. In VB.Net, Authentication often LEADS to Authorization.

TRACE feature in VB.Net allows the user to view if the code is WORKING FINE and if it has been executed in the RIGHT manner. This feature belongs to the system.process.diagnostics namespace. A lot of recent vb net objective questions and ANSWERS were based on this INFORMATION.

Garbage collection, also called automatic memory management, is used to RECYCLE dynamically allocated memory automatically. This function is performed by Garbage collector that reclaims memory if it gets proved that mind will stay unused.

To avoid data loss during conversion, VB.Net uses the Strict Option keyword. It ensures compile-time notification of data type conversions.

Option Explicit is another keyword that is used in a file to declare variables using declare KEYWORDS, such as PRIVATE explicitly, Dim, PROTECTED and Public. However, if UNDECLARED variables persist, an error will occur during the compile time.

An assembly is an element of any .NET APP. It is called a primary unit or building blocks for all .NET applications. It can EITHER be a DLL or an executable file. Keep VISITING our website for in-depth vb net interview questions.

There are two types of assemblies - Private Assembly and SHARED Assembly.

JIT in VB.Net is also called as Just in Time. It is nothing but a compiler that plays a PART during runtime EXECUTION. In VB.Net, we have three types of JIT:

• Pre-JIT: It compiles MSIL CODE into native code in one compilation cycle.
• Econo-JIT: It compiles methods that are called at runtime and REMOVES them from memory after execution.
• Normal JIT: It compiles methods that are only called at runtime.

.NET is a FRAMEWORK developed by Microsoft, WHEREAS VB.Net is an object-oriented, general-purpose programming language.

Have you read our REST of the VB.Net questions and answers?

It's the LATEST version VB 15.8, was released in AUGUST 2018.

VB.Net is one of the most productive languages that can e used for rapidly building a wide range of web, WINDOWS, and MOBILE applications on the .NET Framework.

• Handles pointers indirectly which makes apps more stable and secure.
• VB functionalities can be used using Microsoft.VisualBasic namespace.
• Provides managed CODE execution that results in robust applications.
• Supports optional parameters that MAKE interoperability easier.
• XML is used to transfer data between various layers, which makes data to e passed as text strings.
