突出显示工作簿中的重复项 [英] Highlight duplicates across a workbook

问题描述

我试图突出显示12张工作簿中的重复项.

I am trying to highlight duplicates across a workbook of 12 sheets.

我们跟踪ID#，如果其他任何工作表上都有ID#(值)，我想突出显示该单元格.

We track ID#s and I want to highlight the cell if an ID# (value) is on any of the other sheets.

当我在本工作簿"中使用以下代码时，它适用于一个工作表，而不适用于多个工作表.

When I use the below code in the "This Workbook" it applies within a sheet, and not across the multiple sheets.

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

推荐答案

下面是一个简化的示例，该示例应为您提供一些想法并指明正确的方向. 如果您有任何疑问，请告诉我.

Here is a simplified example that should give you some ideas and point you in the right direction. If you have an questions, let me know.

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)
End Function
