Question

我正在尝试突出显示12张工作簿中的重复项。基本上我们使用它来跟踪ID＃s，如果这个ID＃（值）已经列在任何其他工作表上，我想要突出显示该单元格。我能够提出以下代码，但即使我在“本工作簿”中使用它，它也只在一张纸上应用，而不是在多张纸上。

谢谢！

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)

Dim Rng As Range
Dim cel As Range
Dim col As Range
Dim c As Range
Dim firstAddress As String



'Duplicates will be highlighted in red
Target.Interior.ColorIndex = xlNone
For Each col In Target.Columns
    Set Rng = Range(Cells(1, col.Column), Cells(Rows.Count, col.Column).End(xlUp))
    Debug.Print Rng.Address

    For Each cel In col
        If WorksheetFunction.CountIf(Rng, cel.Value) > 1 Then
            Set c = Rng.Find(What:=cel.Value, LookIn:=xlValues)
            If Not c Is Nothing Then
                firstAddress = c.Address
                Do
                    c.Interior.ColorIndex = 3
                    Set c = Rng.FindNext(c)
                Loop While Not c Is Nothing And c.Address <> firstAddress
            End If
        End If
    Next
Next col

Answer 1

此代码执行的操作是循环显示工作表中的Col A值，然后搜索所有剩余工作表的Col A，如果找到ID，则将单元格背景颜色设置为红色。

这是一个简化的示例，可以为您提供一些想法并指出正确的方向。如果您有任何疑问，请与我联系。

Sub collected_ids_example()
    ' enable microsoft scripting runtime --> tools - references
    ' For convenience I put all code in 2 subs/functions
    ' This code assumes you want every cell with a duplicate id highlighted.
    ' Although it is easy enough to modify that if you want.

    Dim sh As Worksheet
    Dim id_to_addresses As New Dictionary
    Dim id_ As Range

    ' For every worksheet collect all ids and their associated adressses
    ' for the specified range.
    For Each sh In ThisWorkbook.Sheets
        For Each id_ In sh.Range("A4:A100")
            If Not IsEmpty(id_) Then
                If Not id_to_addresses.Exists(id_.Value) Then
                    Set id_to_addresses(id_.Value) = New Collection
                End If
                id_to_addresses(id_.Value).Add get_full_address(id_)
            End If
        Next id_
    Next sh

    ' Color each cell with a duplicate id
    Dim collected_id As Variant
    Dim adresses As Collection
    Dim c As Range
    For Each collected_id In id_to_addresses
        Dim duplicate_address As Variant
        Set adresses = id_to_addresses(collected_id)

        'You have a duplicate if an id is associated with more than 1 addrress
        If adresses.Count >= 2 Then
            For Each duplicate_address In adresses
                Set c = Range(duplicate_address)
                c.Interior.ColorIndex = 3
            Next duplicate_address
        End If
    Next collected_id
End Sub

Private Function get_full_address(c As Range) As String
    get_full_address = "'" & c.Parent.Name & "'!" & c.Address(External:=False)
