VBA-Escribe todas las combinaciones posibles de 4 columnas de datos

Question

He encontrado un script para escribir todas las combinaciones posibles para 3 columnas de datos, pero estoy tratando de modificar el código para escribir 4 columnas y posiblemente 5 y no estoy seguro de cómo. ¡Si alguien puede ayudar sería genial! Intenté hacer lo que creo que debería funcionar agregando variables adicionales a las que seguirían (donde creo que irían lógicamente) pero estoy generando un "Error de compilación: No hacer ciclo" que no puedo explicar.

Aquí está el código para las 3 columnas (sin mis modificaciones) de User Excellll.

La descripción del código está aquí: "Este código tomará los datos de las columnas A, B y C, y dará el resultado que describió en las columnas E, F y G."

Sub combinations()

Dim c1() As Variant
Dim c2() As Variant
Dim c3() As Variant
Dim out() As Variant
Dim j, k, l, m As Long


Dim col1 As Range
Dim col2 As Range
Dim col3 As Range
Dim out1 As Range


Set col1 = Range("A1", Range("A1").End(xlDown))
Set col2 = Range("B1", Range("B1").End(xlDown))
Set col3 = Range("C1", Range("C1").End(xlDown))

c1 = col1
c2 = col2
c3 = col3

Set out1 = Range("E2", Range("G2").Offset(UBound(c1) * UBound(c2) * UBound(c3)))
out = out1

j = 1
k = 1
l = 1
m = 1


Do While j <= UBound(c1)
    Do While k <= UBound(c2)
        Do While l <= UBound(c3)
            out(m, 1) = c1(j, 1)
            out(m, 2) = c2(k, 1)
            out(m, 3) = c3(l, 1)
            m = m + 1
            l = l + 1
        Loop
        l = 1
        k = k + 1
    Loop
    k = 1
    j = j + 1
Loop


out1.Value = out
End Sub

Gracias de antemano por tu ayuda

Answer 1

Aquí hay un enfoque genérico que debería funcionar para cualquier cantidad de columnas / valores (dentro de lo razonable):

Sub ListCombinations()

Dim col As New Collection
Dim c As Range, sht As Worksheet, res
Dim i As Long, arr, numCols As Long

    Set sht = ActiveSheet
    For Each c In sht.Range("A1:D1").Cells
        col.Add Application.Transpose(sht.Range(c, c.End(xlDown)))
        numCols = numCols + 1
    Next c

    res = Combine(col, "~~")

    For i = 0 To UBound(res)
        arr = Split(res(i), "~~")
        sht.Range("H1").Offset(i, 0).Resize(1, numCols) = arr
    Next i

End Sub


''create combinations from a collection of string arrays
Function Combine(col As Collection, SEP As String) As String()

    Dim rv() As String
    Dim pos() As Long, lengths() As Long, lbs() As Long, ubs() As Long
    Dim t As Long, i As Long, n As Long, ub As Long
    Dim numIn As Long, s As String, r As Long

    numIn = col.Count
    ReDim pos(1 To numIn)
    ReDim lbs(1 To numIn)
    ReDim ubs(1 To numIn)
    ReDim lengths(1 To numIn)
    t = 0
    For i = 1 To numIn  ''calculate # of combinations, and cache bounds/lengths
        lbs(i) = LBound(col(i))
        ubs(i) = UBound(col(i))
        lengths(i) = (ubs(i) - lbs(i)) + 1
        pos(i) = lbs(i)
        t = IIf(t = 0, lengths(i), t * lengths(i))
    Next i
    ReDim rv(0 To t - 1) ''resize destination array

    For n = 0 To (t - 1)
        s = ""
        For i = 1 To numIn
            s = s & IIf(Len(s) > 0, SEP, "") & col(i)(pos(i)) ''build the string
        Next i
        rv(n) = s

        For i = numIn To 1 Step -1
            If pos(i) <> ubs(i) Then   ''Not done all of this array yet...
                pos(i) = pos(i) + 1    ''Increment array index
                For r = i + 1 To numIn ''Reset all the indexes
                    pos(r) = lbs(r)    ''   of the later arrays
                Next r
                Exit For
            End If
        Next i
    Next n

    Combine = rv
End Function

Hay un error en la combinación x5 , se usa c4 lugar de c5 (la segunda línea se muestra a continuación):

Do While m <= UBound(c4)
    Do While n <= UBound(c4)

Answer 4

Puede probar el siguiente código para regenerar todas las combinaciones posibles (usando recursión) ------------------------------------ ------------ Public NextLevel As Integer

Private Sub CommandButton1_Click()
    NextLevel = 1
    Call rrd(1, ActiveSheet.Range("F5"), 1, "")
End Sub

Public Function rrd(initiator As Integer, lim As Integer, NextLeg As Integer,     CreatedComb) As Boolean

    If initiator = lim Then
      ActiveSheet.Range("G" & NextLevel) = CreatedComb & "," & initiator
      NextLevel = NextLevel + 1
    Else
      If NextLeg < lim Then
        ActiveSheet.Range("G" & NextLevel) = CreatedComb & "," & initiator
        NextLevel = NextLevel + 1
        Call rrd(initiator + 1, lim, initiator + 1, CreatedComb & "," & initiator)
      End If
      Call rrd(initiator + 1, lim, initiator, CreatedComb)
    End If

End Function
