vba - 删除行时触发 Excel Worksheet_Change 事件

Question

我有一个带有一些 vba 代码的 excel 工作表，当我更改特定单元格时，它会自动将今天的日期设置到它旁边的单元格中。

这一切都很好，但是当我删除该特定单元格上方的整行时，它会自动将日期更改为今天的日期。

这是我用来自动更改单元格的代码:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim WorkRng As Range
Dim Rng As Range
Dim xOffsetColumn As Integer
Set WorkRng = Intersect(Application.Sheets("Example").Range("H10: H306, M10: M306, R10: R306, W10: W306, AB10: AB306, AG10: AG306"), Target)
xOffsetColumn = 1
If Not WorkRng Is Nothing Then
    Application.EnableEvents = False
    For Each Rng In WorkRng
        If Not VBA.IsEmpty(Rng.Value) Then
        Sheets("Example").Unprotect
            Rng.Offset(0, xOffsetColumn).Value = Now
            Rng.Offset(0, xOffsetColumn).NumberFormat = "dd-mm-yyyy"
        Sheets("Example").Protect
        Else
            Rng.Offset(0, xOffsetColumn).ClearContents
        End If
    Next
    Application.EnableEvents = True
End If
End Sub

有人熟悉这个问题吗？

Answer 1

您可以对 Range Target 进行一些测试, 避免执行代码
(与 Goto 或更确切地说 Exit Sub ):

Target.Cells.Count > 1

Target.Rows.Count > 1

Target.Columns.Count > 1

您可以在 Sub 的开头使用这些测试或使用 If Not WorkRng Is Nothing Then
所以你的代码可能是:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim WorkRng As Range
Dim Rng As Range
Dim xOffsetColumn As Integer

If Target.Columns.Count > 1 Then Exit Sub

Set WorkRng = Intersect(Application.Sheets("Example").Range("H10: H306, M10: M306, R10: R306, W10: W306, AB10: AB306, AG10: AG306"), Target)
xOffsetColumn = 1
If Not WorkRng Is Nothing Then
    Application.EnableEvents = False
    For Each Rng In WorkRng
        If Not VBA.IsEmpty(Rng.Value) Then
        Sheets("Example").Unprotect
            Rng.Offset(0, xOffsetColumn).Value = Now
            Rng.Offset(0, xOffsetColumn).NumberFormat = "dd-mm-yyyy"
        Sheets("Example").Protect
        Else
            Rng.Offset(0, xOffsetColumn).ClearContents
        End If
    Next
    Application.EnableEvents = True
End If
End Sub
