查找空白項指數中的二維數組的Excel VBA

Question

我有一個二維數組Dim Line_Qty(6, 2)其值在它類似如下：

**Date  Line_No Quantity** 

2016-11-15 1  5856 

2016-11-15 2  5451 

2016-11-15 3  5499 

2016-11-15  

2016-11-15  

2016-11-15  

什麼，我想找到的第一個空是Line_Qty(4, 1)指數

這樣做的目的是我粘貼這些值在Excel表中，我想停止粘貼，直到數量的最後一項。

我粘貼代碼是這樣

For i = 0 To 6 
For j = 0 To 2 

Worksheets("DY_SET").Cells(i + 1, j + 1).Value = Line_Qty(i, j) 
Worksheets("DY_SET").Range("A" & i + 2).NumberFormat = "yyyy-mm-dd" 

Next j 
Next i 

希望我自己清楚，並在此先感謝

Answer 1

你可以先「截斷」的數組，然後粘貼倖存的值，比如如下：

Dim Line_QtyCopy(0 to 6, 0 to 2) As Variant 

' search Line_Qty first row with empty qty 
For i = 0 To 6 
    If Line_Qty(i, 2) = "" Then Exit For 
Next i 

With Worksheets("DY_SET").Range("A1") '<--| reference target range 
    If i <7 Then '<--| if found empty qty before reaching array end 
     i = i - 1 '<--| update row index to last not emoty one 
     ReDim Line_QtyCopy(0 to i, 0 to 2) '<--| size a new array to the number of rows 
     ' fill it up to last not empty qty in Line_Qty 
     For i = 0 To i 
      For j = 0 To 2 
       Line_QtyCopy(i,j) = Line_Qty(i, j) 
      Next 
     Next 
     .Resize(i).Value = Line_QtyCopy '<--| write it down from cell A1 
    Else 
     .Resize(6).Value = Line_Qty 
    End If 
End With

此代碼逃脫循環時，陣列的某些值爲空。那是你需要的嗎？

For i = 0 To 6 
    For j = 0 To 2 
     If Line_Qty(i, j) = "" Then Exit For 
     Worksheets("DY_SET").Cells(i + 1, j + 1).Value = Line_Qty(i, j) 
    Next j 
    Worksheets("DY_SET").Range("A" & i + 2).NumberFormat = "yyyy-mm-dd" 
Next i
