To test out the code, let's quickly knock together a sample project.

  • Launch Visual Basic
  • Create a new Standard EXE project
  • Paste the Soundex algorithm behind Form1

This simple project will take the values from two Text Boxes, compare them and state whether or not their Soundex codes match.

  • Add two Text Boxes, a Command Button and a Label to your Form, positioning them a little like this:

Ignore regular naming conventions for now. Go on, I dare you. Hey, you've got to have a bit of fun! We're young, innocent...

  • Add this code behind your Command Button:
Private Sub Command1_Click()    Text1.Tag = Soundex(Text1.Text)    Text2.Tag = Soundex(Text2.Text)        If Text1.Tag = Text2.Tag Then        Label1.ForeColor = vbRed - 100        Label1.Caption = "The Soundex codes match!"    Else        Label1.ForeColor = vbBlue        Label1.Caption = "The Soundex codes don't match"    End IfEnd Sub

That's it! You've created your simple test application.

  • Press F5 to run

To test the project, enter two values such as 'JON' and 'JOHN' and hit the Command Button. You might also want to experiment with:

  • Visual, Vezual
  • Richard, Ricardo
  • Forrest, Forest, Forrester
  • Checker, Chequer
  • Sideroad, Syde-rowd
  • Coronation, Carnation
