Question

我会说我不是VBA的专家。我有一个VBA代码，它在一个单元格中附加选定列表中的多个值。代码有效，但现在我想将代码应用于多个单元格。

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)
'Code by Sumit Bansal from https://trumpexcel.com
' To Select Multiple Items from a Drop Down List in Excel
Dim Oldvalue As String
Dim Newvalue As String
Application.EnableEvents = True
On Error GoTo Exitsub
If Target.Address = "$A$7" Then
  If Target.SpecialCells(xlCellTypeAllValidation) Is Nothing Then
    GoTo Exitsub
  Else: If Target.Value = "" Then GoTo Exitsub Else
    Application.EnableEvents = False
    Newvalue = Target.Value
    Application.Undo
    Oldvalue = Target.Value
      If Oldvalue = "" Then
        Target.Value = Newvalue
      Else
        If InStr(1, Oldvalue, Newvalue) = 0 Then
            Target.Value = Oldvalue & "," & Chr(10) & Newvalue
      Else:
        Target.Value = Oldvalue
      End If
    End If
  End If
End If
Application.EnableEvents = True
Exitsub:
Application.EnableEvents = True
End Sub

如何扩展我的代码以使用单元格范围

$A$7:$A$18

而不是"$A$7"，以便我可以将VBA代码应用于Excel中的多个单元格。

Answer 1

更改

If Target.Address = "$A$7" Then

到

If Not Intersect(Target, Range("A7:A18")) Is Nothing Then

Answer 2

我使用了外卡。

O(n^2)

要

maximum = 0
for idx in range(1, N - 1):
    left = min(l[0: idx])
    right = min(l[idx + 1:])
    middle = l[idx]

    if left < middle and right < middle:
        new_max = middle - left + middle - right
        maximum = max(new_max, maximum)
