Excel vba如何將數字輸出組合到Excel行？

Question

我需要找出一種方法來輸出結果的所有組合的行數（最好，如果可能在一個單一行）

我有8位數{1,2,3,4,5， 6,7,8}組合的典型輸出是i; j（i，j是來自集合的數字，如果選擇兩個，則爲i < j）。生成結果很簡單：

Dim Myarray_2 As String 
    Dim sht as Worksheet 
    set sht = Sheet1 

    Myarray_2 = ""   ' pick up 2 out of 8 
    For j = 2 To 8 
     For i = 1 To j - 1 
     sht.Cells(i + 1, j + 1) = Str(MyArray(i)) + ";" + Str(MyArray(j)) 
      Myarray_2 = Myarray_2 + Str(MyArray(i)) + ";" + Str(MyArray(j)) + "|" 
     Next i 
    Next j 

這是拿起2的例子，我已經將它輸出到工作表的行。

我也有解決方案，拿起3，現在我的問題是其餘的情況下，如何得到輸出？

下面是用於拾取3溶液：

Dim Myarray_3 As String 
     Myarray_3 = ""   ' 3 out of 8 
    k = 3 
    Do While k >= 3 And k <= 8 
    'inner loop through i j 
     For j = 2 To k - 1 
      For i = 1 To j - 1 
       sht.Cells(i + 11, j - 1 + m) = Str(MyArray(i)) + ";" + Str(MyArray(j)) + ";" + Str(MyArray(k)) 
       Myarray_3 = Myarray_3 + Str(MyArray(i)) + ";" + Str(MyArray(j)) + ";" + Str(MyArray(k)) + "|" 
      Next i 
     Next j 

    k = k + 1 
    m = m + 7 
    Loop 

通過MYARRAY（ⅰ）被初始化爲MYARRAY（i）所述的方式= I

我發現一些代碼，我從另一個有好的程序員，我改變了代碼以適應你的問題。如果您將N設爲您的set/array的成員數量，那麼您將擁有（2^N）-1組合，但是您可以使用自己的條件對其進行過濾。請注意，在您的問題中，使用您的條件進行過濾時，成員的順序將非常重要。

該代碼將首先生成所有組合，然後應用條件。數組結果將是主輸出，因此它的大小將始終爲（2^N）-1。陣列結果 - 過濾將是你想要的。

請注意，如果您有從左到右排序的數字，數組Result和Result_filtered將是相同的。

您可以將任何格式的輸出打印到任何工作表中。

該方法使用按位計算，以獲得組合：

如果N = 2，則數comnibations的將是（2^2）-1 = 3 我們總是排除0」當然 {的二進制A，B} - > {[00]，[01]，[10]，[11]} - > {ignore，[B]，[A]，[AB]}
