How to disable changes in a cell using vba? - vba

Question

I am working with the bellow code:
This code do for Example: If I input any value in cell A1, cell B1 display a time stamp.
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
With Target
If .Count > 1 Then Exit Sub
If Not Intersect(Range("B1:B10"), .Cells) Is Nothing Then
Application.EnableEvents = False
If IsEmpty(.Value) Then
.Offset(0, 1).ClearContents
Else
With .Offset(0, 1)
.NumberFormat = "hh:mm AM/PM"
.Value = Now
End With
End If
Application.EnableEvents = True
End If
End With
End Sub
What I am trying to do now is to protect/not editable from the user the cell "B1:B10" once time stamp has made by the macro. I google on how to protect but I am having hard time to insert those code I found. Can anyone help me how I construct/insert this code to my original code?
Private Sub Worksheet_Change(ByVal Target As Range)
'set your criteria here
If Target.Column = 1 Then
'must disable events if you change the sheet as it will
'continually trigger the change event
Application.EnableEvents = False
Application.Undo
Application.EnableEvents = True
MsgBox "You cannot do that!"
End If
End Sub
Or this code:
'select the cell you want to be editable
Worksheets("Sheet1").Range("B2:C3").Locked = False
'then protect the entire sheet but still vba program can modify instead.
Worksheets("Sheet1").Protect UserInterfaceOnly:=True
Thanks to Kazjaw. Here is the final code.
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
'Protect cell "B1:B10"
Worksheets("Sheet1").Cells.Locked = False
Worksheets("Sheet1").Range("B1:b10").Locked = True
Worksheets("Sheet1").Protect Password:="pass", UserInterfaceOnly:=Tru
With Target
If .Count > 1 Then Exit Sub
If Not Intersect(Range("B1:B10"), .Cells) Is Nothing Then
Application.EnableEvents = False
If IsEmpty(.Value) Then
.Offset(0, 1).ClearContents
Else
With .Offset(0, 1)
.NumberFormat = "hh:mm AM/PM"
.Value = Now
End With
End If
Application.EnableEvents = True
End If
End With
End Sub

If you want to protect only Range B1:B10 then you need to run this sub only once:
Sub ProtectCellsInB()
Worksheets("Sheet1").Cells.Locked = False
Worksheets("Sheet1").Range("B1:b10").Locked = True
Worksheets("Sheet1").Protect Password:="pass", UserInterfaceOnly:=True
End Sub
I made a modification- I added a password to protection which you can delete.
If you are not sure how to run it once then you could add the whole internal code at the end of your Private Sub Worksheet_Change(ByVal Target As Excel.Range)
