Comment trouver la dernière ligne contenant des données dans une colonne spécifique et sur une feuille spécifique?
Que diriez-vous:
Sub GetLastRow(strSheet, strColumn)
Dim MyRange As Range
Dim lngLastRow As Long
Set MyRange = Worksheets(strSheet).Range(strColumn & "1")
lngLastRow = Cells(Rows.Count, MyRange.Column).End(xlUp).Row
End Sub
Re Comment
Ce
Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row
Renverra le numéro de ligne de la dernière cellule même si une seule cellule de la dernière ligne contient des données.
Vous devriez utiliser .End(xlup)
mais au lieu d’utiliser 65536, vous voudrez peut-être utiliser:
sheetvar.Rows.Count
De cette façon, cela fonctionne pour Excel 2007 qui, je crois, a plus de 65 536 lignes.
Simple et rapide:
Dim lastRow as long
Range("A1").select
lastRow = Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row
Exemple d'utilisation:
cells(lastRow,1)="Ultima Linha, Last Row. Youpi!!!!"
'or
Range("A" & lastRow).Value = "FIM, THE END"
function LastRowIndex(byval w as worksheet, byval col as variant) as long
dim r as range
set r = application.intersect(w.usedrange, w.columns(col))
if not r is nothing then
set r = r.cells(r.cells.count)
if isempty(r.value) then
LastRowIndex = r.end(xlup).row
else
LastRowIndex = r.row
end if
end if
end function
Usage:
? LastRowIndex(ActiveSheet, 5)
? LastRowIndex(ActiveSheet, "AI")
Public Function LastData(rCol As Range) As Range
Set LastData = rCol.Find("*", rCol.Cells(1), , , , xlPrevious)
End Function
Usage: ?lastdata(activecell.EntireColumn).Address
Voici une solution pour rechercher la dernière ligne, la dernière colonne ou la dernière cellule. Il aborde le dilemme du style de référence A1 R1C1 pour la colonne trouvée. J'aimerai pouvoir donner du crédit, mais je ne peux pas trouver/je ne me souviens pas d'où je l'ai eu, alors "Merci!" à qui que ce soit qui a posté le code original quelque part là-bas.

Sheets("Sheet1").Select
MsgBox "The last row found is: " & Last(1, ActiveSheet.Cells)
MsgBox "The last column (R1C1) found is: " & Last(2, ActiveSheet.Cells)

MsgBox "The last column (A1) found is: " & Last(4, ActiveSheet.Cells)
End Sub

Toutes les solutions reposant sur des comportements intégrés (tels que .Find
et .End
) ont des limitations qui ne sont pas bien documentées (voir mon autre réponse pour plus de détails).
J'avais besoin de quelque chose qui:
Worksheet_Change
sans se sentir léthargique)La solution ci-dessous:
UsedRange
pour trouver la limite supérieure du numéro de ligne (pour effectuer une recherche rapide de la "dernière ligne" réelle dans le cas habituel où elle se rapproche de la fin de la plage utilisée);UsedRange
, nous devons la sauter)(Pas de test, désolé)
' Returns the 1-based row number of the last row having a non-empty value in the given column (0 if the whole column is empty)
Private Function getLastNonblankRowInColumn(ws As Worksheet, colNo As Integer) As Long
' Force Excel to recalculate the "last cell" (the one you land on after CTRL+END) / "used range"
' and get the index of the row containing the "last cell". This is reasonably fast (~1 ms/10000 rows of a used range)
Dim lastRow As Long: lastRow = ws.UsedRange.Rows(ws.UsedRange.Rows.Count).Row - 1 ' 0-based
' Since the "last cell" is not necessarily the one we're looking for (it may be in a different column, have some
' formatting applied but no value, etc), we loop backward from the last row towards the top of the sheet).
Dim wholeRng As Range: Set wholeRng = ws.Columns(colNo)
' Since accessing cells one by one is slower than reading a block of cells into a VBA array and looping through the array,
' we process in chunks of increasing size, starting with 1 cell and doubling the size on each iteration, until MAX_CHUNK_SIZE is reached.
' In pathological cases where Excel thinks all the ~1M rows are in the used range, this will take around 100ms.
' Yet in a normal case where one of the few last rows contains the cell we're looking for, we don't read too many cells.
Const MAX_CHUNK_SIZE = 2 ^ 10 ' (using large chunks gives no performance advantage, but uses more memory)
Dim chunkSize As Long: chunkSize = 1
Dim startOffset As Long: startOffset = lastRow + 1 ' 0-based
Do ' Loop invariant: startOffset>=0 and all rows after startOffset are blank (i.e. wholeRng.Rows(i+1) for i>=startOffset)
startOffset = IIf(startOffset - chunkSize >= 0, startOffset - chunkSize, 0)
' Fill `vals(1 To chunkSize, 1 To 1)` with column's rows indexed `[startOffset+1 .. startOffset+chunkSize]` (1-based, inclusive)
Dim chunkRng As Range: Set chunkRng = wholeRng.Resize(chunkSize).Offset(startOffset)
Dim vals() As Variant
If chunkSize > 1 Then
vals = chunkRng.Value2
Else ' reading a 1-cell range requires special handling <http://www.cpearson.com/Excel/ArraysAndRanges.aspx>
ReDim vals(1 To 1, 1 To 1)
vals(1, 1) = chunkRng.Value2

J'aimerais ajouter un moyen plus fiable en utilisant UsedRange
pour trouver la dernière ligne utilisée:
lastRow = Sheet1.UsedRange.Row + Sheet1.UsedRange.Rows.Count - 1
De même pour trouver la dernière colonne utilisée, vous pouvez voir ceci
Résultat dans la fenêtre Immédiate:
?Sheet1.UsedRange.Row+Sheet1.UsedRange.Rows.Count-1
21
Last_Row = Range("A1").End(xlDown).Row
Juste pour vérifier, supposons que vous souhaitiez imprimer le numéro de la dernière ligne avec les données de la cellule C1.
Range("C1").Select
Last_Row = Range("A1").End(xlDown).Row
ActiveCell.FormulaR1C1 = Last_Row
Public Function GetLastRow(ByVal SheetName As String) As Integer
Dim sht As Worksheet
Dim FirstUsedRow As Integer 'the first row of UsedRange
Dim UsedRows As Integer ' number of rows used
Set sht = Sheets(SheetName)
''UsedRange.Rows.Count for the empty sheet is 1
UsedRows = sht.UsedRange.Rows.Count
FirstUsedRow = sht.UsedRange.Row
GetLastRow = FirstUsedRow + UsedRows - 1
Set sht = Nothing
End Function
sheet.UsedRange.Rows.Count: retourne le nombre de lignes utilisées, n'inclut pas la ligne vide au-dessus de la première ligne utilisée
si la ligne 1 est vide et que la dernière ligne utilisée est 10, UsedRange.Rows.Count renverra 9 et non 10.
Cette fonction calcule le premier numéro de rangée de UsedRange plus le nombre de rangées de UsedRange.
