November 2019 Newsletter Competition - Winner / Answer

This month's competition was won by Neil Whitten of AXA, to whom a £50 Amazon voucher is winging its way. 

The competition asked you to use a list of numbers to colour in a spreadsheet:

Start of the numbers

Each row gave a cell row and column number, together with the RGB colour to use.


Here's what you got if you followed the instructions:

Flappy owl

It's flappy owl!

This image was created by Andy Gould, who created a series of blogs and videos showing how to create a Flappy Owl game in VBA (based on Flappy Bird, if anyone remembers it?).

The obvious way to solve the problem was to write a macro to loop over the rows, processing each in turn.  Here was my solution:

Sub CreatePicture()

'the list of instructions

Dim InstructionRange As Range

'the left column of each instruction

Dim InstructionCell As Range

'each cell in turn being coloured

Dim NextCellToColour As Range

'set column of instructions (row 2 down to bottom)


Range("A1").Offset(1, 0).Select

Set InstructionRange = Range(ActiveCell, ActiveCell.End(xlDown))

'return to picture sheet so can see things happening


'reset picture


'return to picture, and loop over instruction rows

For Each InstructionCell In InstructionRange.Cells

'set the row/column number of the next cell to colour

Set NextCellToColour = Cells(InstructionCell.Value, InstructionCell.Offset(0, 1).Value)

NextCellToColour.Interior.Color = RGB( _

InstructionCell.Offset(0, 2).Value, _

InstructionCell.Offset(0, 3).Value, _

InstructionCell.Offset(0, 4).Value _


Next InstructionCell

MsgBox "All done - enjoy the picture!"

End Sub

However, one person filled in the colours manually (I won't reveal their name or what they were meant to be doing at the time!).  Another person solved the person correctly, but decided the picture showed a turkey, while a third person submitted the cryptic answer "I tawt I taw a puddy tat".
