Create Mathematical Trick by displaying seven numerical tables using MSFlexGrid
ExeFile

Introduction

I am using seven numerical tables to create this Mathematical Trick. I found the idea of this trick in my old papers but I don't remember from which book or magazine I read it before. I confess that my work is a translation of this idea to a VB6 program.

Background

  • Choose number from 1 to 100, keep it in your mind.
  • I shall display (7) tables.
  • Every table contains some numbers.
  • Search for the number of your choice in every table.
  • If you find it: Click (Yes) button.
  • If not: Click (No) button.
  • After displaying last table (number 7):
  • I shall tell you your choice number!

Using the Code

The following code is an example to fill MSFlexGrid with numbers:

Dim c As Integer
Dim r As Integer
Dim n As Integer
Dim T As Integer

   With NumGrid
      T = 1
      For r = 0 To 4
         For c = 0 To 9
            .TextMatrix(r, c) = Str(T)
            T = T + 2
         Next c
      Next r

Please refer to the source code (Sub FillTab) to see how I fill the grid with numbers seven times.

Remarks

You can find the source code when you extract the file SourceFile.zip and you can find the *.exe when you extract the file ExeFile.zip.

Last Words

I hope that you enjoy this trick. If anybody knows the exposition of this trick, please let us know.
