VBA for Excel : Error 424 Object Required

Question

我正在完成一个脚本，该脚本验证 Sheet1 的 A 列(“INCIDENTS”)中的单元格是否在 Sheet2 的 A 列(“INCDB”)重复，如果单元格重复，它将删除 Sheet1 中的整行。

问题是在第一个循环(并删除该行)之后，它给了我 424 错误并突出显示 If iSrc.Cells.Value = iDst.Cells.Value Then
关于原因的任何想法？这是代码:

Sub CTDeleteDuplicatePaste()

Dim ws1 As Worksheet
Dim ws2 As Worksheet
Dim iSrc As Variant
Dim iDst As Variant
Dim rng As Range

Set ws1 = Sheets("INCIDENTS")
Set ws2 = Sheets("INCDB")

For Each iSrc In ws1.Range("A5:A9999" & LastRow)
    For Each iDst In ws2.Range("A5:A9999")
        If iSrc.Cells.Value = iDst.Cells.Value Then
        If rng Is Nothing Then
            Set rng = iSrc.EntireRow
        Else
            Set rng = Union(rng, iSrc.EntireRow)
        End If
            rng.EntireRow.Delete

        End If

    Next iDst
Next iSrc

End Sub

我会在没有对象的情况下这样做 iSrc和 iDst .从相反的顺序 - 这段代码对我有用:

Sub CTDeleteDuplicatePaste()

Dim ws1 As Worksheet
Dim ws2 As Worksheet
Dim i As Long
Dim j As Long

Set ws1 = Sheets("INCIDENTS")
Set ws2 = Sheets("INCDB")

For i = 9 To 5 Step -1        'change 9 to 9999 for your real data
    For j = 9 To 5 Step -1    'change 9 to 9999 for your real data
        If Len(ws1.Cells(i, 1).Value) > 0 Then
            If ws1.Cells(i, 1).Value = ws2.Cells(j, 1).Value Then
                ws1.Cells(i, 1).EntireRow.Delete
                GoTo nextIteration
            End If
        End If
    Next
nextIteration:
Next

End Sub
