I have a code to log usage in an excel sheet, but I get one bug, and one issue

Question

This is a universal log system, that a few people here and myself have created. I\'m rather proud of it... I am running into two issues... if someone can help with the sollution

Answer 1

This worked for me. Ideally you'd have a named range on the sheet being tracked which you could use to restrict tracking only to changes occuring inside that range.

Const MAX_TRACKED_CELLS As Long = 50
Dim PreviousValues As Object

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim c As Range
    Dim haveDict As Boolean, val, addr

    haveDict = Not PreviousValues Is Nothing

    If Target.Cells.Count <= MAX_TRACKED_CELLS Then
        For Each c In Target.Cells
            addr = c.Address()
            If haveDict Then
                If PreviousValues.exists(addr) Then
                    val = PreviousValues(addr)
                End If
            Else
                val = "{unknown}"
            End If

            If c.Value <> val Then
                Debug.Print "Changed:", addr, IIf(val = "", "Empty", val), _
                            " to ", IIf(c.Value = "", "Empty", c.Value)
            End If

        Next c
    End If


End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Dim c As Range

    If PreviousValues Is Nothing Then
        Set PreviousValues = CreateObject("scripting.dictionary")
    Else
        PreviousValues.RemoveAll
    End If

    If Target.Cells.Count <= MAX_TRACKED_CELLS Then
        For Each c In Target.Cells
            PreviousValues.Add c.Address(), c.Value
        Next c
    End If

End Sub
