Force the user to select only one specific cell - vba

Question

I cannot lock my sheet because I need to access some cells to run macros.
I want a macro that selects cell (F1) whenever the user try to select any other cell.
I need a macro like this one, I guess:
Private Sub Worksheet_Change(ByVal Target As Range)
End Sub

Answer 1

Put this code in the worksheet module:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Call Cells(1, 6).Select
End Sub

Answer 2

Like other guys wrote, is better to unprotect the sheet, play your macro and protect the sheet but, if you think that disable all cells, minus the cell that you identify, is the best way, you can use this code:
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
If Not Intersect(Target, Range("F10")) Is Nothing Then 'use your free cell
do
Else
Application.Undo
MsgBox "you can modify only the cell(F10)" 'Just to inform what is the cell editable
Range("F10").Select
End If
Application.EnableEvents = True
End Sub

Answer 3

Here are 2 options:
.
1. Without protecting the sheet - in each sheet module to customize "unlocked" cell (Ex. "C3")
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
With Target
If .Column <> 3 Or .Row <> 3 Or .CountLarge > 1 Then Application.Undo
End With
Application.EnableEvents = True
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Application.EnableEvents = False
With Target
If .Column <> 3 Or .Row <> 3 Or .CountLarge > 1 Then Cells(3, 3).Select
End With
Application.EnableEvents = True
End Sub
.
2. Protecting the sheet - in ThisWorkbook module
Private Sub Workbook_Open()
Dim ws As Worksheet
For Each ws In ThisWorkbook.Worksheets
protectWS ws
Next
End Sub
Private Sub Workbook_SheetActivate(ByVal Sh As Object)
protectWS Sh
End Sub
Public Function protectWS(Optional ByRef ws As Worksheet = Nothing) As Boolean
If ws Is Nothing Then Set ws = Application.ActiveSheet
If Not isWSProtected(ws) Then
ws.Protect Password:=vbNullString, _
DrawingObjects:=True, _
Contents:=True, _
Scenarios:=True, _
UserInterfaceOnly:=True, _
AllowFormattingCells:=False, _
AllowFormattingColumns:=False, _
AllowFormattingRows:=False, _
AllowInsertingColumns:=False, _
AllowInsertingRows:=False, _
AllowInsertingHyperlinks:=False, _
AllowDeletingColumns:=False, _
AllowDeletingRows:=False, _
AllowSorting:=False, _
AllowFiltering:=False, _
AllowUsingPivotTables:=False
End If
End Function
Private Function isWSProtected(Optional ByRef ws As Worksheet = Nothing) As Boolean
isWSProtected = ws.ProtectContents Or _
ws.ProtectDrawingObjects Or _
ws.ProtectScenarios
End Function
Option 1 forces users to cell C3
can be moved to ThisWorkbook module, with parameters for row and column
Option 2 is using an empty password, and allows VBA execution (UserInterfaceOnly)
