在VBA中通過查找列和列中的值來刪除Excel中的行

Question

我正在嘗試建立一個宏，該宏將找到標題為“ Total Labor”的列，並刪除該列中所有具有“ 0”的行。 我正在生成多個報告，“總勞力”列將更改位置，因此這就是我需要查找的原因。 到目前為止，我已經有了這段代碼，但是當我運行它時，什么都沒有發生。 任何幫助表示贊賞。

Sub DeleteRows()
Dim FoundCell As Range
Dim rng As Range
Application.ScreenUpdating = False
Set rng = Worksheets(ActiveSheet.Name).Range("A1:BB100").Find(what:="Total Labor", _
    LookAt:=xlWhole, MatchCase:=False)
Set FoundCell = rng.Find(what:="0")
Do Until FoundCell Is Nothing
    FoundCell.EntireRow.Delete
    Set FoundCell = rng.FindNext
Loop

End Sub

Answer 1

怎么樣：

Sub DeleteRow()
    Dim colly As Long, killer As Range, nRow As Long
    colly = 0
    For i = 1 To Columns.Count
        If Cells(1, i).Value = "Total Labor" Then
            colly = i
            Exit For
        End If
    Next i
    If colly = 0 Then
        MsgBox "Header not found"
        Exit Sub
    End If
    nRow = Cells(Rows.Count, colly).End(xlUp).Row
    For i = 1 To nRow
        If Cells(i, colly).Value = 0 Then
            If killer Is Nothing Then
                Set killer = Cells(i, colly)
            Else
                Set killer = Union(killer, Cells(i, colly))
            End If
        End If
    Next i
    If killer Is Nothing Then
    Else
        killer.EntireRow.Delete
    End If
End Sub

您需要復制Excel UI提供的FindAll功能。 這是在VBA中實現此目標的代碼列表。 將其保存到.bas文件，然后在找到'Total Labor'后在宏中調用它，然后瀏覽從FindAll返回的范圍並對其執行.Delete 。

Sub DeleteRows()

Dim FoundCell As Range
Dim rng As Range

Application.ScreenUpdating = False

Set rng = Worksheets(ActiveSheet.Name).Range("A1:BB100").Find(what:="Total Labor", _
    LookAt:=xlWhole, MatchCase:=False)

If rng Is Nothing Then
    Msgbox "Total Labor Not Found"
Else
    Set SearchRange = rng.EntireColumn
    FindWhat = "0"
    Set FoundCells = FindAll(SearchRange:=SearchRange, _
                            FindWhat:=FindWhat, _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByColumns, _
                            MatchCase:=False, _
                            BeginsWith:=vbNullString, _
                            EndsWith:=vbNullString, _
                            BeginEndCompare:=vbTextCompare)

    If FoundCells Is Nothing Then
        Debug.Print "Value Not Found"
    Else
        For Each FoundCell In FoundCells
            FoundCell.EntireRow.Delete
        Next FoundCell
    End If

End If

End Sub

' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result.  If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

Answer 3

第一：如果設置Application.ScreenUpdating = False ，請確保在子結束之前將其重置為True 。 如果宏崩潰，您可能會發現自己無法使用該應用程序，直到重新啟動Excel或運行另一個設置Application.ScreenUpdating = True宏。

現在，回答您的問題：代碼的問題在於，代碼中定義的rng只會是包含“總勞力”的單元格。 當您在該范圍內搜索值“ 0”時， Set FoundCell = rng.Find(what:="0")計算結果為“ Nothing”，因此，當您開始執行do循環時，它符合FoundCell Is Nothing的條件FoundCell Is Nothing ，立即轉到End Sub 。

這樣的事情應該可以解決問題：

    Sub DeleteRows2()

    On Error GoTo ErrorHandler

    Application.ScreenUpdating = False

    '~~>dim variables and set initial values
        Dim rTotalLaborHeader As Range
            Set rTotalLaborHeader = Worksheets(ActiveSheet.Name).Range("A1:BB100").Find(what:="Total Labor", _
                LookAt:=xlWhole, MatchCase:=False)
        Dim rTotalLaborColumn As Range
            Set rTotalLaborColumn = Range(Cells(2, rTotalLaborHeader.Column), Cells(1048576, rTotalLaborHeader.Column).End(xlUp))
            'Set rTotalLaborColumn = Range(rTotalLaborHeader.Offset(1, 0), rTotalLaborHeader.End(xlDown))
        Dim rLaborRow As Range

    '~~>Loop to delete rows with zero Total Labor
        For Each rLaborRow In rTotalLaborColumn
            If rLaborRow.Value = 0 Then rLaborRow.EntireRow.Delete
        Next rLaborRow

CleanupAndExit:
    Application.ScreenUpdating = True
    Exit Sub

ErrorHandler:
    Resume CleanupAndExit

End Sub
