Undo changes in range
 

Hello to all

When the user CHANGES an entry in range A5:F64, I'd like a msgbox to ask for
confirmation, or else undo the change.

So far I can tell if the change is in the desired range (see below), but I
have no clue as to how to undo the changes if not confirmed by the user.
Any ideas would be appreciated.

Thanks, Brian


Private Sub Worksheet_Change(ByVal Target As Range)

Dim WatchRange As Range
Dim ChangedRange As Range

Set WatchRange = Range("A5:F64")
Set ChangedRange = Intersect(Target, WatchRange)

If ChangedRange Is Nothing Then
MsgBox "You changed a cell NOT in the WatchRange", vbOKOnly
Else
MsgBox "You changed a cell in the WatchRange", vbOKOnly
End If

End Sub

Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)

Dim WatchRange As Range
Dim ChangedRange As Range
Dim Resp As Long

Set WatchRange = Range("A5:F64")
Set ChangedRange = Intersect(Target, WatchRange)

If ChangedRange Is Nothing Then
MsgBox "You changed a cell NOT in the WatchRange", vbOKOnly
Else
Resp = MsgBox(Prompt:="You changed a cell in the WatchRange" & vbLf _
& "Are you sure?", Buttons:=vbYesNo)

If Resp = vbYes Then
'do nothing
Else
With Application
.EnableEvents = False
.Undo
.EnableEvents = True
End With
End If

End If

End Sub

Dave - works like a charm. Thank you.

Dave - great advice! I'll be able to incorporate this in my code too.

Would it be difficult to NOT give the warning if the cell is originally
blank? For example, I type 'John' in a blank cell. (no msgbox). Now I
CHANGE it to 'Jon' (msgbox asking for confirmation as in your reply to
Bri).

The bad news is that you could change multiple cells at one time. You could
keep track of the old values and do a comparison. Maybe using a hidden
worksheet that gets populated with the values in that sheet when the workbook
opens???

I put this under the ThisWorkbook module:

Option Explicit
Private Sub Workbook_Open()
Me.Worksheets("sheet1").Cells.Copy
Me.Worksheets("sheet1Mirror").Range("a1").PasteSpe cial Paste:=xlPasteValues
Application.CutCopyMode = False
End Sub

Then this goes behind the worksheet with the "monitoring" going on:

Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)

Dim WatchRange As Range
Dim ChangedRange As Range
Dim Resp As Long
Dim myCell As Range
Dim FoundANonBlank As Boolean

Set WatchRange = Range("A5:F64")
Set ChangedRange = Intersect(Target, WatchRange)

If ChangedRange Is Nothing Then
MsgBox "You changed a cell NOT in the WatchRange", vbOKOnly
Else
FoundANonBlank = False
For Each myCell In ChangedRange.Cells
If IsEmpty(Me.Parent.Worksheets("sheet1Mirror") _
.Range(myCell.Address).Value) Then
'do nothing, it was empty
Else
FoundANonBlank = True
Exit For
End If
Next myCell

Resp = vbYes
If FoundANonBlank = True Then
Resp = MsgBox(Prompt:="You changed a cell in the WatchRange" _
& vbLf _
& "Are you sure?", Buttons:=vbYesNo)
End If

If Resp = vbYes Then
'copy value to mirrored sheet
For Each myCell In ChangedRange.Cells
Me.Parent.Worksheets("sheet1Mirror") _
.Range(myCell.Address).Value = myCell.Value
Next myCell
Else
With Application
.EnableEvents = False
.Undo
.EnableEvents = True
End With
End If

End If

End Sub

It seemed to work ok under light testing.
