Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

The text file in the above folder contains a message - your task is to read it in line by line:

The text file

The start of the message (you could, of course, just read it manually!).

 

To achieve this task, first create a reference to the Microsoft Scripting Runtime object library.  Now write code to set a string variable to a blank string to begin with, and accumulate text within it as you read in each line.  Something like this should do the trick:

'read in the next character's line

NextCharacter = ts.ReadLine

'accumulate this in a string variable

msg = msg & NextCharacter

Obviously you'll need to include this within a loop reading lines in from the text file until you reach the end, and declare all the necessary variables!

If you succeed, your macro should display the meaning of life:

The meaning of life

Clearly the message you accumulate and display will be different.

 

Save your workbook as Solving the mysteries of life.xlsm, then close it down.
