Firstly, I know 0 about programming or VBA, but I found this code which auto locks cells after you enter data in them.
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
' Place this code in the worksheet code module. ' The subroutine unprotects the sheet and IF an entry is made ' in an empty ("") cell, the cell is locked and then the ' sheet's protection is turned back on. Any further ' attempts to edit the cell generate the password msgbox. ' You can set the range to one cell ("A1") or an area ("A1:Z300"). ' 1. Use Format - Cells - Protection to unlock the cells ' in the range where one time entries are to be allowed. ' 2. Protect the worksheet with the same password as ' you use twice in the following subroutine (thepassword).
On Error GoTo justenditall
Application.EnableEvents = False If Not Intersect(Target, Range("A1:A20")) Is Nothing Then If Target.Value <> "" Then ActiveSheet.Unprotect Password:="thepassword" Target.Locked = True End If End If
justenditall: Application.EnableEvents = True End Sub
Now I want to make this only work when the file is saved. For example, when an employee opens up the file he or she is able to enter any new data, but not edit old data, and once saved, they will not be able to edit the data they just entered.
I hope this makes sense.
