Console Input and Output

Every algorithm in computing requires taking in some data as input and outputting the results somehow. In this chapter, we will discuss simple ways to interact with a user in each Visual Basic family member. For gathering input from the user in this chapter, we will focus on reading data from a keyboard used by the user on the client of the applications we will develop. For output, we will send raw data back to the user's screen in a simple model of rows of text with line delimiters.

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

  • Programming input and output with Visual Basic.NET
  • Programming input and output with Visual Basic Classic
  • Programming input and output with Visual Basic for Applications (VBA)
  • Programming input and output with VBScript
  • Programming input and output with Classic ASP
  • Programming input and output with ASP.NET
