Question

我试图删除所有包含＆＃34; H＆＃34;的字符串的行。在P列中。然而，宏工作，它每次只删除一半必要的行。这是因为代码中的For循环 - 当删除行时，下一行将与已删除的行具有相同的i值，并被Next i跳过

Dim LastRow As Long

'Finds last row
With ActiveSheet
    LastRow = .Cells(.Rows.count, "P").End(xlUp).Row
End With

'Iterates through rows in column B, and deletes the row if string contains "H"
For i = 4 To LastRow
    If InStr(1, Range("P" & i), "H") <> 0 Then Rows(i).EntireRow.Delete
Next i

'Message Box when tasks are completed
  MsgBox "Complete"

如果删除一行以获取所有行，是否有办法让For循环重复相同的i值？

Answer 1

执行此操作的标准方法是以相反的顺序迭代。

Dim LastRow As Long

'Finds last row
With ActiveSheet
    LastRow = .Cells(.Rows.count, "P").End(xlUp).Row
End With

'Iterates in reverse through rows in column B, and deletes the row if string contains "H"
For i = LastRow To 4 Step -1 
    If InStr(1, Range("P" & i), "H") <> 0 Then Rows(i).EntireRow.Delete
Next i

'Message Box when tasks are completed
  MsgBox "Complete"

尝试过滤通配符*H*并删除可见行。

Option Explicit

    Sub qweqrwtqrweq()
        if autofiltermode then .autofiltermode = false
        With ActiveSheet  '<~~much better to use thge ACTUAL WORKSHEET NAME!! e.g. with worksheets("sheet1")
            With .Range(.Cells(4, "P"), .Cells(.Rows, Count, "P").End(xlUp))
                .AutoFilter fiedl:=1, Criteria1:="*h*"
                If CBool(Application.subtotla(103, .Cells)) Then
                    .Cells.etirerow.Delete
                End If
            End With
        End With
        if autofiltermode then .autofiltermode = false
        MsgBox "Complete"
    End Sub

批量操作几乎始终比逐行检查更有效。
