Un dernier coup de main

Bonsoir

Qui aurait la gentillesse de me modifier cette macro pour que je puisse faire 300 lignes (De A1 à A300)?
Merci d'avance
Pitou

Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Application.Intersect(Target, Range("C1")) Is Nothing Then
Select Case Target.Value
Case Is = 1: Range("D1") = Range("A1") * Range("B1")
Case Is = 2: Range("E1") = Range("A1") * Range("B1")
Case Is = 3: Range("F1") = Range("A1") * Range("B1")
Case Is = 4: Range("G1") = Range("A1") * Range("B1")
End Select
End If
End Sub

Bonsoir Pitou,

Je te propose :

Private Sub Worksheet_Change(ByVal Target As Range)
Dim L As Integer
If Not Application.Intersect(Target, Range("C1:C300")) Is Nothing Then
   L = Target.Row
   Select Case Target.Value
      Case Is = 1: Cells(L, 4).Value = Cells(L, 1) * Cells(L, 2)
      Case Is = 2: Cells(L, 5).Value = Cells(L, 1) * Cells(L, 2)
      Case Is = 3: Cells(L, 6).Value = Cells(L, 1) * Cells(L, 2)
      Case Is = 4: Cells(L, 7).Value = Cells(L, 1) * Cells(L, 2)
   End Select
End If
End Sub

Mais on peut faire plus simple :

Private Sub Worksheet_Change(ByVal Target As Range)
Dim L As Integer, C As Integer
If Not Application.Intersect(Target, Range("C1:C300")) Is Nothing Then
   L = Target.Row
   C = Target.Value
&nbsp;&nbsp;&nbsp;If C > 0 And C < 5 Then Cells(L, C + 3).Value = Cells(L, 1) * Cells(L, 2)
End If
End Sub
