Question

我为数据验证列编写了一些代码，以自动生成单元格，这似乎是第一次工作，但是在关闭文件并再次打开后，它不起作用。

谢谢您的帮助

Private Sub Worksheet_Change(ByVal Target As Range)

 On Error GoTo ErrHandler
  Application.EnableEvents = False


Dim catCode As String

If Target.Column = 2 Then

    catCode = Target.Value
    Select Case catCode

Answer 1

在Application.EnableEvents = False块中移动If Target.Column = 2将防止您的代码在不重置Application.EnableEvents标志的情况下退出。随着将来代码的更改（尤其是在使用Application.EnableEvents语句时），管理Exit Sub标志可能会成为问题。避免此问题的另一种方法是与行为逻辑分开处理Application.EnableEvents标志管理……之类。

Private Sub Worksheet_Change(ByVal Target As Range)

    Application.EnableEvents = False

On Error Resume Next     
    LoadCells Target

    Application.EnableEvents = True

End Sub

Private Sub LoadCells(ByVal Target As Range)

Dim catCode As String

If Target.Cells.Count <> 1 Then Exit Sub
If Target.Column = 2 Then

    catCode = Target.Value
    Select Case catCode
    
    Case "AUTOMATIC LEVEL", "DIGITAL LEVEL"
    Target.Offset(0, 7) = "19/99"
    Target.Offset(0, 8) = 1

    Case "BAROMETER", "THERMOMETER"
    Target.Offset(0, 7) = "24/99"
    Target.Offset(0, 8) = 1
    
    Case "BRACKET BUBBLE"
    Target.Offset(0, 7) = "23/99"
    Target.Offset(0, 8) = 0.5

为什么工作表的代码更改不起作用？
