Protect Data after entry

[Guest]

Once data is entered into a cell I need it to be protected (automatically)
and not able to be changed or deleted.

I am using this for a auditing receivables and once I see the receivable on
the spreadsheet, I do not want anyone to be able to change or remove it.
Need to also be able to add additional receivables to spreadheet.

A formula that if a cell has data it becomes protected was my thought but ???.

A formula cannot do anything but return results.

You could use event code in the worksheet.

First, select Column B and Format>Cells>Protection. Uncheck "locked"

If your column of receivables is other than B, edit the

If Target.Cells.Column = 2 Then to something other than 2

Copy/paste the code below to the worksheet by right-click on sheet tab and "View
Code"

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo enditall
Application.EnableEvents = False
If Target.Cells.Column = 2 Then
ActiveSheet.Unprotect Password:="justme"
N = Target.Row
If Excel.Range("B" & N).Value <> "" Then
Excel.Range("B" & N).Locked = True
End If
End If
enditall:
Application.EnableEvents = True
ActiveSheet.Protect Password:="justme", DrawingObjects:=True, _
Contents:=True, Scenarios:=True
End Sub

To cap it off close the sheet module by clicking on the "x".

Right-click on the workbook/project and select VBAProject Properties then
"Lock project for viewing"

You can password protect this module so prying eyes can't see it and obtain
the password("justme").

You now save the workbook and close Excel....the VBAProject locking won't come
into effect until Excel is closed out fully.

If the users enable macros and if no one of them knows how to crack a
VBAProject password, you should be good to go.

Is their a way to modify this macro to work if I only want to lock 15 of the
cells in a particular column after the data has been entered??

Thanks,

In the absence of details on which cells and column try this.

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo enditall
Application.EnableEvents = False
If Not Intersect(Target, Me.Range("A1:A15")) Is Nothing Then
ActiveSheet.Unprotect Password:="justme"
With Target
If .Value <> "" Then
.Locked = True
'.Offset(0, 1).Locked = True ' to lock column B cell
End If
End With
End If
enditall:
Application.EnableEvents = True
ActiveSheet.Protect Password:="justme", DrawingObjects:=True, _
Contents:=True, Scenarios:=True
End Sub

Gord - I entered the code, but it does not seem to be working.

I want to be able to protect the data after it is entered into column "b"...

For expamle:
1) User enters 11/13/06 in cell b2
2) Now they are in cell b3
3) They go back to cell b2 and try to enter 11/14/06
4) The entery of 11/14/06 into cell b2 is not allowed

It would be nice if I was the only one that could then change the entry... I
like the password option in your code.

Thanks,

Nick

Change the range A1:A15 to B1:B15

As far as only you being able to edit the range of cells I guess you would have
to have the event code pull up your username and if valid, disable events so's
you could do the editing.

If not valid, continue with the event.

I think someone not so VBA-challenged as myself would have to address that.

It only works once... after the first data entry the sheet remains protected.

I need to only protect the last data entry cell.

For expamle:
1) User enters 11/13/06 in cell b2
1a) Protection enable for Cell b2
2) Now they are in cell b3
3) They go back to cell b2 and try to enter 11/14/06
3a) The entery of 11/14/06 into cell b2 is not allowed
4) They go to cell b3 enter 11/14/06
4a) Protection enable for Cell b3
5) Now they are in cell b4
6) They go back to cell b3 and try to enter 11/15/06
etc......

It seems like the code you posted on 8/5/06 should work, but I can't seem to
get that to work either...

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo enditall
Application.EnableEvents = False
If Target.Cells.Column = 2 Then
ActiveSheet.Unprotect Password:="justme"
N = Target.Row
If Excel.Range("B" & N).Value <> "" Then
Excel.Range("B" & N).Locked = True
End If
End If
enditall:
Application.EnableEvents = True
ActiveSheet.Protect Password:="justme", DrawingObjects:=True, _
Contents:=True, Scenarios:=True
End Sub

My bad, I forgot to unlock the other cells first... It works great!

Thanks!

I have never used 2000 version so can't speak to that.

With 2002 and 2003 if you set the Autofilter columns before you protect the
sheet your code should work.

Try this google search return for how to employ userinterfaceonly method to
allow autofiltering in Excel 2000

It worked... I had to put it in the tab code (called the sub filters) and
call it from the sub that locked the cells. Here it is... Thanks!!!

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo enditall
Application.EnableEvents = False
If Target.Cells.Column = 2 Then
ActiveSheet.Unprotect Password:="justme"
N = Target.Row
If Excel.Range("B" & N).Value <> "" Then
Excel.Range("B" & N).Locked = True
End If
End If
enditall:
Application.EnableEvents = True
ActiveSheet.Protect Password:="justme", DrawingObjects:=True, _
Contents:=True, Scenarios:=True
Call filters
End Sub

Sub filters()
With Worksheets("sheet1")
.Protect Password:="justme", userinterfaceonly:=True
'.EnableOutlining = True
.EnableAutoFilter = True
End With
End Sub

Cleaner code... no extra sub routine required.

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo enditall
Application.EnableEvents = False
If Target.Cells.Column = 2 Then
ActiveSheet.Unprotect Password:="justme"
N = Target.Row
If Excel.Range("B" & N).Value <> "" Then
Excel.Range("B" & N).Locked = True
End If
End If
enditall:
Application.EnableEvents = True

With Worksheets("sheet1")
.Protect Password:="justme", userinterfaceonly:=True
'.EnableOutlining = True
.EnableAutoFilter = True
End With

End Sub
