Introduction

In this introductory lesson to the Visual Basic Language, we will create a small console application and perform some simple calculations.

Practical LearningPractical Learning: Creating the Application

  1. Start Microsoft Visual Studio
  2. In the Visual Studio 2026 dialog box, click Create a New Project
  3. In the Create a New Project dialog box, in the Languages combo box, select Visual Basi.
    In the list of projects templates, select Console App (it should be selected already)
  4. Click Next
  5. In the Configure Your New Project dialog box, change the Project Name to PayrollEvaluation1 and set the Location of your choice
  6. Click Next
  7. In the Additional Information dialog box, in the Framework combo box, select the highest version (.NET 10.0 (Long Term Support)).
    Click Create
  8. Change the document as follows: 
    Module Program
    Sub Main(args As String())
        Console.WriteLine("Payroll Evaluation")
        Console.WriteLine("===================================================")
        Console.WriteLine("Enter the following pieces of information")
        Console.WriteLine("---------------------------------------------------")
        Console.WriteLine("Employee Information")
        Console.WriteLine("---------------------------------------------------")
        Console.Write("First Name:        ")
        Dim FirstName = Console.ReadLine()
        Console.Write("Last Name:         ")
        Dim LastName = Console.ReadLine()
        Console.Write("Hourly Salary:     ")
        Dim HourlySalary = CDbl(Console.ReadLine())
        Console.WriteLine("===================================================")
        Console.WriteLine("Time worked")
        Console.WriteLine("---------------------------------------------------")

        Console.Write("Monday:            ")
        Dim Monday = CDbl(Console.ReadLine())

        Console.Write("Tuesday:           ")
        Dim Tuesday = CDbl(Console.ReadLine())

        Console.Write("Wednesday:         ")
        Dim Wednesday = CDbl(Console.ReadLine())

        Console.Write("Thursday:          ")
        Dim Thursday = CDbl(Console.ReadLine())

        Console.Write("Friday:            ")
        Dim Friday = CDbl(Console.ReadLine())

        Dim TimeWorked = Monday + Tuesday + Wednesday + Thursday + Friday

        Dim RegularTime = TimeWorked
        Dim OverTime = 0.00
        Dim OvertimePay = 0.00
        Dim RegularPay = HourlySalary * TimeWorked

        If TimeWorked > 40.0 Then
            RegularTime = 40.0
            RegularPay = HourlySalary * 40.0
            OverTime = TimeWorked - 40.0
            OvertimePay = HourlySalary * 1.5 * OverTime
        End If

        Dim NetPay = RegularPay + OvertimePay

        Console.WriteLine("===================================================")
        Console.WriteLine("Payroll Evaluation")
        Console.WriteLine("===================================================")
        Console.WriteLine("Employee Information")
        Console.WriteLine("---------------------------------------------------")
        Console.WriteLine($"Full Name:     {FirstName} {LastName}")
        Console.WriteLine($"Hourly Salary: {HourlySalary:f}")
        Console.WriteLine("===================================================")
        Console.WriteLine("Time Worked Summary")
        Console.WriteLine("--------+---------+-----------+----------+---------")
        Console.WriteLine(" Monday | Tuesday | Wednesday | Thursday | Friday")
        Console.WriteLine("--------+---------+-----------+----------+---------")
        Console.WriteLine("{0,6:f}  | {1,6:f}  | {2,7:f}   | {3,7:f}  | {4,5:f}",
                          Monday, Tuesday, Wednesday, Thursday, Friday)
        Console.WriteLine("========+=========+===========+==========+=========")
        Console.WriteLine("                              Pay Summary")
        Console.WriteLine("---------------------------------------------------")
        Console.WriteLine("                              Time      Pay")
        Console.WriteLine("---------------------------------------------------")
        Console.WriteLine("                  Regular:{0,9:f}{1,12:f}", RegularTime, RegularPay)
        Console.WriteLine("---------------------------------------------------")
        Console.WriteLine("                  Overtime:{0,8:f}{1,12:f}", OverTime, OvertimePay)
        Console.WriteLine("===================================================")
        Console.WriteLine("                  Net Pay:{0,21:f}", NetPay)
        Console.WriteLine("===================================================")

Using an Opposite Conditional Statement

In the previous section, we use a Greater Than operator to check a condition. That operator has an opposite, which is the Less Than Or Equal operator. We will uase apply as an example.

Practical LearningPractical Learning: Using an Opposite Conditional Statement

  1. Change the document as follows: 
    Module Program
    Sub Main(args As String())
        Console.WriteLine("Payroll Evaluation")
        Console.WriteLine("===================================================")
        Console.WriteLine("Enter the following pieces of information")
        Console.WriteLine("---------------------------------------------------")
        Console.WriteLine("Employee Information")
        Console.WriteLine("---------------------------------------------------")

        Dim FirstName = Console.ReadLine()
        Console.Write("Last Name:         ")
        Dim LastName = Console.ReadLine()
        Console.Write("Hourly Salary:     ")
        Dim HourlySalary = CDbl(Console.ReadLine())
        Console.WriteLine("===================================================")
        Console.WriteLine("Time worked")
