Visual Basics Assignment Help
Visual Basic or simply VB is a user-friendly object-oriented programming language. It allows developers to build a variety of secure and robust applications that can run in the .NET framework. It boasts of improved security and interoperability features.
Our visual basic assignment help service covers topics from basic to advanced levels. We have hired eminent online visual basic programmers who have extensive experience in the language. We guarantee that they can curate impressive projects for you within your deadline.
Setting up the Visual Basic Development Environment
As we said in the introduction section, visual basic is based on the .NET framework. As a result, you must install the .NET framework component on your machine before you can run VB applications. All PCs running on the Windows operating system by default already have the .NET framework installed. If you want to learn more about how the .NET framework is installed and integrated with VB, avail our visual basic assignment help.
Visual Studio IDE
Microsoft's visual studio is the preferred Integrated Development Environment for building applications using programming languages such as C-sharp, F-sharp, Visual Basic, etc. You need to buy a license from Microsoft if you want to install and use visual studio for commercial purposes. On the other hand, if you use this IDE for learning purposes, then you can take advantage of the free visual studio community version, which is also provided by Microsoft.
You can go to the official website of Visual Basic to download and install it on your laptop. If you do not have access to this IDE, you can ask our experts to assist you with your assignment. Now that you already have a visual studio running in your PC, we can now learn how to create a project.
Creating a project in Visual Studio with the help of our Visual Basic Project Help Experts
When you run the visual studio for the first time, you are prompted to sign in. You can skip this step as it is optional. In the next dialog box, you need to choose your development settings and color theme. You can click on the start visual studio option once you finish selecting the required options.
After you have launched a visual studio, you can use VB programming language to create a new console application. To do this, you can go to File, then New, and then select a project. A new popup will appear. Here, choose visual basic on the left pane and then click on the console app.
You can give your project any name and also select an appropriate location path to save your project files. When you complete this step, click on OK. A new console application gets created once you click on the OK button. It is one of the processes of how you can create a console application using visual basic in a visual studio IDE. If you did not get the basics right but have an assignment due, avail of our help right away.
Visual Basic Data Types
Data types in visual basic define a type of data that is held by a variable. Some of the examples of data types in visual basic include integer, float, string, etc. It is mandatory to define a variable with a required data type to indicate the type of data the variable can hold in your application. It is because VB is a strongly typed programming language. So variables must be declared before performing any operations.
The syntax used to define data types in Visual Basic
You can use the syntax below to define data types in visual basic.
Dim [variable Name] As [Data type]
Dim [variable Name] As [Data Type]
From the syntax above, you can see that we added a required data type after the variable name. We did this to tell the compiler the type of data that can be held by the variable. Also, in the syntax:
- Dim declares and allocates storage space for one or more variables
- [Variable Name] refers to the name of the variable that will hold values in our application
- As is a clause in the declaration statement. It allows you to define the data.
- [Data Type] refers to the type of data our variable can hold. A data type can be an integer, float, string, etc.
- [Value] allows us to assign a required value to the data types
The VB professionals associated with us hold top certifications in the subject. When you sign up for our Visual Basic project help, we deliver assignments on-time.
We have outlined in the table below the data types that are supported in Visual Basic
|Boolean||The size depends on the platform||True or False|
|Date||8 bytes||0.00.00 am 1/1/01 - 11:59:59pm 12/31/9999|
|Decimal/Float||16 bytes||(+ or -) 1.0 x10e-28 to 7.9 x 10e28|
|Double||8 bytes||-1.79769313486232e308 to 1.79769313486232e308|
|Integer||4 bytes||-2,147,483,648 to 2,147,483,647|
|long||8 bytes||-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807|
|Object||8 bytes on a 64-bit system and 4 bytes on a 32-bit system||A variable of type object can store any type of data|
|SByte||1 byte||-128 to 127|
|Short||2 bytes||-32,768 to 32,767|
|Single||4 bytes||-3.4028235E+38 through -1.401298E-45 † for negative values; 1.401298E-45 through 3.4028235E+38 † for positive values|
|String||The size depends on the platform||The range of a string is from 0 to approximately 2 billion Unicode characters|
|UInteger||4 bytes||0 to 4,294,967,295|
|ULong||8 bytes||0 to 18,446,744,073,709,551,615 (1.8...E+19 †)|
|Ushort||2 bytes||0 to 65,535|
|User-defined||The size depends on the platform||The range of each member of the structure is determined by its data type. The range is also independent of the ranges of other members.|

For Loop in VB
In a visual basic programming language, we can define the For loop using the following syntax:
For variable As [Data Type] = start To end
//Statements to Execute
For loop has been defined with different parameters on the syntax above. The variable parameter is mandatory and must be numeric. The data type parameter might be optional, but it defines the data type for the variable. Finally, the start and end parameters define the initial and final value of the variable.

The exit keyword in Visual Basic stops the execution of the For loop statement based on your requirements. Also, we can create a visual basic nested For loop.
Visual Basic Objects and Classes
Objects and classes in visual basic are interrelated. A Class is a collection of various data members (fields, properties, etc.) and member functions. An object is an instance of a class used to define the defined methods and properties.
A Visual Basic class is a data structure that combines the various types of data members such as events, member functions, events properties, and fields into a single unit. The keyword class can create a Class in visual basic. You can use this syntax:
Public Class users
Properties, Methods, Events, etc.
In the syntax above, the class users define using the keyword class and the public access modifier. Public access specifier allows users to create objects for class 'users.' The programmer can also create the required properties, methods, events, and fields used in the application.
Visual Basic Class members
- Fields – These are the variables of the class
- Methods – They are the computations and actions that can be performed by the class
- Properties – Actions associated with writing and reading named properties of a class
- Events - Notifications generated by the class
- Constructors – It refers to the actions initialized by instances of the class or the class itself.
The others include operators, constants, indexers, finalizers, and types.
Objects in VB are the concrete entities of classes. They are created using the 'new' keyword, followed by the name of the class.
