I’m struggling

Please HELP, I need a solution like this urgently

THANX Kobus

How do I call you’re code.

I have tried to call “LogStandardChanges” from the excel AutoOpen macro, with no luck

…Scott…

lMaxRow = Application.WorksheetFunction.Max(wbNewStan.Sheets(1).UsedRange.Rows.Count, _
wbOldStan.Sheets(1).UsedRange.Rows.Count)
lMaxCol = Application.WorksheetFunction.Max(wbNewStan.Sheets(1).UsedRange.Columns.Count, _
wbOldStan.Sheets(1).UsedRange.Columns.Count)

May give the incorrect results if the used range does not include A1. (Well, sometimes it could happen .)

Dim wbNewStan As Workbook
Dim wbOldStan As Workbook

Dim LastRow1 As Long
Dim LastRow2 As Long
Dim LastCol1 As Long
Dim LastCol2 As Long
Dim LastRow As Long
Dim LastCol As Long

‘some nice assignments

With wbNewStan.Worksheets(1).UsedRange
LastCol1 = .Columns(.Columns.Count).Column
LastRow1 = .Rows(.Rows.Count).Row
End With

With wbOldStan.Worksheets(1).UsedRange
LastCol2 = .Columns(.Columns.Count).Column
LastRow2 = .Rows(.Rows.Count).Row
End With

With Application
LastRow = .Max(LastRow1, LastRow2)
LastCol = .Max(LastCol1, LastCol2)
End With

1. Create a very hidden copy of the worksheet
2. For all cell’s to be monitored, add conditional formatting comparing its value with the value in the equivalent cell of the control worskheet.

I find this works well as it only highlights values that differ from the original file, even if the value is changed many times.

There are some optimisations you could make:

You only need to check on unprotected cells. Proteced cells won’t change(if sheets are proteced of course). Make shure you make named ranges of them. this way you can check selectively, and you are not dependent on actual cell addresses. You need to do this for all unprotected cells. Walking through all named ranges that are not protected will certainly be faster.

You also need to discern between “tables” and fixed ranges. “Table” ranges are difficult because their cell amounts can grow and shrink. You’ll need to understand if they do this horizontally or vertically. You also need to understand if your table is postionally linked to other ranges/tables (with cell references), or linked through cell values (with lookups). The last situation means you have a key column(s) to match records with an older version of your table. In fact you are now creating more or less a multi value version database inside excel (like e.g. ORACLE has). To make this not too hard either save the whole table with each change, or maintain the table in a SQL database, and make it multiversion in there. Link to it in Excel and use that.
