Good morning Mr Excel Forum,
Thanks in advance everybody for reading, helping, advicing.
i am looking to track changes in an excel sheet in a non-shared workbook. The old value should be written to the cell's comment on top of the previous tracking comment. It is supposed to not be modified by users. Unfortunately i receive an error runtime 91.
example of required comment :
Previous Value was azer
Revised 09-07-2017
By Yan
Previous Value was YRZX
Revised 03-07-2017
By Cin
Here is the code I added:
Option Explicit
Public VolDvaL As Variant
Public preValue As Variant
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Count > 1 Then Exit Sub
Target.ClearComments
Target.AddComment.Text Text:="Previous Value was " & preValue & Chr(10) & "Revised " & Format(Date, "mm-dd-yyyy") & Chr(10) & "By " & Environ("UserName") & VolDvaL
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Count > 1 Then Exit Sub
If Target = "" Then
preValue = "a blank"
Else: preValue = Target.Value
End If
If Target.Comment.Text = "" Then
VolDvaL = ""
Else: VolDvaL = Target.Comments
End If
End Sub
I assume there is some information missing like " how to protect the comment from modification" and "how to add the previous value saved" but I am pretty sure somebody here will find how to insert this in the upper code
Many thanks in advance for your kind assistance.
