vba - 保护非空单元格VBA

Question

我添加了 VBA 代码，双击后将时间或日期插入到单元格中。我设法让事情进展顺利。

我正在努力解决的问题是在输入时间/日期后保护和锁定单元格。

当我双击/尝试编辑非空单元格时，我收到运行时错误。调试后，让我困惑的行是 "Target.Formula = Format(Now, "ttttt")"。

我也无法抛出错误消息。

我已经很接近了!

如有任何建议，我们将不胜感激!

我的代码:

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)


    If Not Intersect(Target, Range("C:E")) Is Nothing Then
        Cancel = True
        Target.Formula = Format(Now, "ttttt")
      End If

    If Not Intersect(Target, Range("A:A")) Is Nothing Then
        Cancel = True
        Target.Formula = Format(Now, "dd/mm/yyyy")

      End If


End Sub


Private Sub Worksheet_Change(ByVal Target As Range)

   On Error GoTo ErrorHandler

    Dim xRg As Range
    Set xRg = Intersect(Range("A:A,C:E"), Target)
    If xRg Is Nothing Then Exit Sub
    Target.Worksheet.Unprotect Password:="123"
    xRg.Locked = True
    Target.Worksheet.Protect Password:="123"

   Exit Sub
ErrorHandler:
   MsgBox "Cell already filled"

   Resume Next


End Sub

Protect your worksheet一旦使用 UserInterfaceOnly:=True 参数，您就不必取消保护/保护来使用 VBA 更改单元格内容。

sub protectOnce()
    worksheets("sheet1").unprotect password:="123"
    worksheets("sheet1").protect password:="123", UserInterfaceOnly:=True
end sub
