Project Part I

In our first project, we want to use the skills we have learned to build a simple calculator for each VB family member. The calculator should allow the user to enter a simple mathematical operation such as addition, subtraction, multiplication, or division. The calculator should also enable the user to enter the two operands used in the calculation. The calculator will then show the result and allow for another calculation.

In this chapter, we’re going to cover the following main topics:

  • Developing a calculator in the VB.NET console
  • Developing a calculator in VB6
  • Developing a calculator in Visual Basic for Applications (VBA)
  • Developing a calculator in VBScript
  • Developing a calculator in Classic ASP
  • Developing a calculator in ASP.NET
