Its access level has been set to Public to make it publicly accessible.
#SIMPLE PAYROLL PROGRAM IN VB CODE#
Step 3) Run the code by clicking the Start button from the toolbar. Step 2) Add the following code: Imports SystemĪrea = Rectangle.length * Rectangle.breadthĬonsole.WriteLine("Area of Rectangle is : ", sum) Step 1) Create a new console application. The Inherits denotes any parent class that it inherits.įollowing is an example code to create a class in VB.Net:.It is an optional parameter and can take values like Public, Protected, Protected Friend, Friend, and Private. The accessModifier is the access level of the defined class.The attributeList denotes a list of attributes that are to be applied to the class.This is described in the following syntax: _ To define a class, we use the Class keyword, which should be followed by the name of the class, the class body, and the End Class statement. The class members are the methods and variables defined within the class. It does not mean that a class definition is a data definition, but it describes what an object of that class will be made of and the operations that we can perform on such an object.Īn object is an instance of a class. In VB.Net, we use classes to define a blueprint for a Data Type. The screen will pause and wait for the user to perform an action to close it. This line will prevent the screen from closing or exiting soon after the program has been executed.This statement makes the program print the text Hello Guru99 on the console when executed. Remember this was imported into the code. The WriteLine method belongs to the Console class, and it is defined inside the System namespace. This is where we have specified the behavior of the primary method.It defines what the module will do when it is executed. This marks the entry point in all VB.Net programs. In this line, we defined the Main sub-procedure. A procedure can be a Function, Sub, Get, Set, AddHandler, Operator, RemoveHandler, or RaiseEvent.
This means that the procedure will define the class behavior. It is inside procedures where you should define your executable code. A VB.Net module or class can have more than one procedures.Anyone reading through your code will find it easy to understand. Use them to explain the meaning of various statements in your code. The purpose of comments is to improve the readability of the code. The VB.Net compiler will not process this part. To mark it as a comment, we added a single quote (‘) to the beginning of the sentence. It is inside this module that you will be able to define the data and methods to be used by your program. Hence we must have a class module in every program. Here, we have declared a module named Module1. After that, we will be able to access all the methods that have been defined in that namespace without getting an error. What we are doing is that we are including a namespace with the name System into our programming structure. This is called the namespace declaration.Let us discuss the various parts of the above program:
