David Watling’s Excel programs

 

Notes for running my macros:

  1. Set Excel security to medium before running these (tools->macro->security)
  2. I have endeavoured to make these totally harmless, however these programs are loaded & run at your own risk
  3. Most of my program create a toolbar.  If you do not have macros enabled, the toolbar will not be deleted when you exit Excel.  You can delete it either by enabling the macros before closing Excel, or by deleting them yourself. (view->toolbars->customise)

 

Virtual tiler

This is a great little utility for tiling images together.  I used it for planning the tiling for my shower room, and for joining all the little maps you can get off the internet, to make a bigger one!

Sudoku solver

This does the three stages of Sodoku solving – I call them ‘Distill’, ‘Reduce possibles’ and ‘Recursive’ (recursive is only used in ‘Super solver’ mode).  I have tried to set the recursion levels such that it doesn’t spend too much time on each ‘branch’, but I occasionally come across the odd ‘Extreme diabolical bastard’ Soduko puzzle which it fails on.  If you know your way around VBA, you can play with the recursion levels.

Maze

Creates a maze out of Excel cells.  The ‘repeat’ creates a maze, and then solves it.  And repeats until you press ‘escape’.  Just therapeutic.  If you are interested in programming, this is a great example of recursion for both the ‘create’ and the ‘solve’ parts.  There is hardly anything to it!
