Enumerating a multi-dimensional array
 

Hi,

I've built a multi-dimensional array from a table and would like to
enumerate the whole thing, but I'm confused. Can anyone help me out?

Thank you,

Perhaps you could clarify what "enumerate the whole thing" means?

where arr is a 2-D array...

for j = 0 to ubound(arr,2)
for i = 0 to ubound(arr,1)
wscript.echo arr(i,j)
next
next


where arr is a 3-D array...

for k = 0 to ubound(arr,3)
for j = 0 to ubound(arr,2)
for i = 0 to ubound(arr,1)
wscript.echo arr(i,j,k)
next
next

Enumerating a multi-dimensional array
 

Alan,

I want to print out every defined value in the array. For instance if this
were a standard (one-deminsional) array, I could write:

Sub PrintArray()
Dim fruits As Variant
Dim i As Integer
fruits = Array("grapes", "pineapples", "kiwi")
For i = LBound(fruits) To UBound(fruits)
Debug.Print fruits(i)
Next i
End Sub

But my array isn't one deminsional, and I don't quite understand how my data
is being put into the array. There's a second argument to LBound and UBound
that I don't quite understand yet, so I want to print the contents of my
array so I can see how my data is organized.

Does that clear it up?

Thank you,

Robert

Well, sorta'. You say it's multi-dimensional and not one-dimensional; is
it two-dimensional? Three-dimensional? Is it a secret?

If it's two-dimensional,

For i = LBound(fruits,1) to UBound(fruits,1)
For j=LBound(fruits,2) to UBound(fruits,2)
Debug.Print i,j,fruits(i,j)
Next j
Next i

If it's three-dimensional,

For i = LBound(fruits,1) to UBound(fruits,1)
For j=LBound(fruits,2) to UBound(fruits,2)
For k=LBound(fruits,3) to UBound(fruits,3)
Debug.Print i,j,k,fruits(i,j,k)
Next k
Next j
Next i

etc.

Enumerating a multi-dimensional array
 

Alan,

Thank you. I also figured it out. Here's what I came up with (sorry about
the double spaces):

Dim j As Integer

Dim k As Integer

For j = LBound(locationNames, 1) To UBound(locationNames, 1)

For k = LBound(locationNames, 2) To UBound(locationNames, 2)

Sheets("Contents").Range("F3").Cells(j, k).Value = locationNames(j,
k)

Next k

Next j

Thank you for answering my question.

Rather than looping, consider

Sheets("Contents").Range("F3").Resize(UBound(locat ionNames,1),_
UBound(locationNames,2)).Value = locationNames

For Each elm In ary
WScript.echo elm
Next

Apparently, VBScript stores arrays in column-major order, so this will
produce:

ary(0, 0, 0, ...)
ary(1, 0, 0, ...)
ary(2, 0, 0, ...)
...
ary(n, 1, 0, ...)
ary(n, 2, 0, ...)
...
etc.

But it's the simplest, most general way.
