多維整數

Question

在Excel VBA代碼中，定義變量時，它是如何使代碼能夠定義具有多個值範圍的整數變量的？

例如：

Dim iCount(a to b, x to y) as Integer 

Answer 1

有在VBA兩種類型的陣列。固定陣列，其中所述限制是服用的未知的陣列B中定義爲

N = 100 
Dim A() as Long 
ReDim(1 to N) 
... 
Erase A 

類似地，對於多維數組

Dim A() as Long 
ReDim(1 to N, 1 to M) 
... 
Erase A 

現在對於一個例子，定義爲

Dim A(1 to 100) as Long 

常數動態數組大小，並通過給每個值加1來創建一個數組A.

' Given a 1D array B() make a copy into A() 
Dim A() as Long 
Dim i_low as Long, i_high as Long, i as Long 
' Discover array bounds of B 
i_low = LBOUND(B,1) : i_high = UBOUND(B,1) 
' Declare array size 
ReDim A(i_low to i_high) 
For i=i_low to i_high 
    ' Calculate each element of the new array 
    A(i) = B(i) + 1 
Next i
