Как заблокировать ячейку vba excel

I have an Excel worksheet that acts like an application, with form control buttons allowing users to ‘navigate’ through records. First, Previous, Next & Last cycle appropriately through one of the worksheets records, displaying the values in my ‘form’ worksheet.

When users are not in Edit or Add Mode, I would like to lock the cells to prevent users from modifying contents.

I tried Range(«A1:O24»).Locked = True, but I am still able to type new values into the cells.

Anyone know how to accomplish this? I need my vba code to be able to assign new values to the cells as users ‘navigate’, but to prevent users from entering new values unless in Add or Edit mode.

Search for your condition whether user was not in Edit or Add mode and then locking your range and finally protect your worksheet.

Let’s say for example in one case, if you want to locked cells from range A1 to I50 then below is the code:

Worksheets("Enter your sheet name").Range("A1:I50").Locked = True
ActiveSheet.Protect Password:="Enter your Password"

In another case if you already have a protected sheet then follow below code:

ActiveSheet.Unprotect Password:="Enter your Password"
Worksheets("Enter your sheet name").Range("A1:I50").Locked = True
ActiveSheet.Protect Password:="Enter your Password"

Try using the Worksheet.Protect method, like so:

Sub ProtectActiveSheet()
    Dim ws As Worksheet
    Set ws = ActiveSheet
    ws.Protect DrawingObjects:=True, Contents:=True, _
        Scenarios:=True, Password="SamplePassword"
End Sub

You should, however, be concerned about including the password in your VBA code. You don’t necessarily need a password if you’re only trying to put up a simple barrier that keeps a user from making small mistakes like deleting formulas, etc.

Also, if you want to see how to do certain things in VBA in Excel, try recording a Macro and looking at the code it generates. That’s a good way to get started in VBA.

You can also do it on the worksheet level captured in the worksheet’s change event. If that suites your needs better. Allows for dynamic locking based on values, criteria, ect…

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

Sub LockCells()

Range("A1:A1").Select

Selection.Locked = True

Selection.FormulaHidden = False

ActiveSheet.Protect DrawingObjects:=False, Contents:=True, Scenarios:= False, AllowFormattingCells:=True, AllowFormattingColumns:=True, AllowFormattingRows:=True, AllowInsertingColumns:=True, AllowInsertingRows:=True, AllowInsertingHyperlinks:=True, AllowDeletingColumns:=True, AllowDeletingRows:=True, AllowSorting:=True, AllowFiltering:=True, AllowUsingPivotTables:=True

End Sub
