ExcelTrack Changes - Text and Formulas with user name and time stamp

Ease of UseIntermediateVersion tested with2003Submitted by:arkusMDescription:This Macro would be used to track all _changes_ to a sheet, whether they are data entry changes or formula changes. and displays the old value in a seperate sheet.Discussion:I developed by modifying lenze's change macro (http://vbaexpress.com/kb/getarticle.php?kb_id=909). This version will track changes in a new sheet, I created this code for a Excel application that I created and maintained but did not use. Itwas intended it to be a history maker for the file. **NB** this macro renders the "undo" function useless. **NB** this maco will not show data cahnges when multiple cells are selected. It will show the range that cahnged but does not showeach cell change. There is password protection in the code but it is commented out. CODE: '.Protect Password:="Secret" Modification ideas: - Track change on a new, hidden, file.Code:

How to use:1. The code should be copied in its entirety into the "thisWorkbook" code s

heet.2. When a value is entered then changed the macro should fire.3. Close the Code window and exit the Editor.Test the code:1. Enter data on any sheet. Change the value, a new tab should be created called "Tracker", navigate to this tab and you should see the old and new valuesyour user name and time you made the change.2. Test on single cell entries and test on multiple cells to see if this will work for you.
