I need to store information in a 2 dimensional array. I understand ArrayList
only works for a single dimensional array, is that correct ?
So, I use the 2 dimensional array like in VB6. I pass the array into a
subroutine, and inside it I "Redim Preserve" the array to increase the
number of item in the array. I got the error "Redim statement requires an
array", but arr is an array. HOw can I fix this problem ? Or, how can I do
ArrayList for 2 dimensional array ?
THank you very much.
Private arr(COM_MAX, 0) As String
LoadArr(arr)
Sub LoadArr(ByRef arr As Array)
lNumComm = 0
For x = 1 to 1000
ReDim Preserve arr(COM_MAX, lNumComm)--->Redim statement requires an array

Pass it in the same way you define the array, eg
Sub LoadArr(ByRef arr As int(,))
BTW, redim preserve does a complete copy of every element in the array every
time it's called. In your loop that will mean half a million copies for each
column.

Michael C is right about the Redim Preserve. I wouldn't do that.
I'd use an arraylist or a generic list (depending on what version
of .Net you're using.)

Or redim at the start or redim at set intervals.

why not have an Arraylist (or preferably a generic List(of T)) of Arraylists?

You can put an array into each element of the arraylist I guess. Although
there is nothing wrong with using Redim Preserve if you limit it's use by
increasing the size of the array, say, every 1000 elements.

Seems a simple question, but I can't find a simple answer:
I have created a two dimensional array. I wish to send the data, a row at a time to a graph plotting routine which is expected a one dimension array.
I could create a temporary one dimensional array and populate from the original array and then pass it to the routine, but this would seem to be long winded (read slow), and may well give me problems, as the previous values in the...

Hi all,
I have a two-dimensional array of data, f.x int's. We can imagine that
the array is "really large". Now I want the data in it and store this
in a one-dimensional array.
The obvious way to do this is a nested for-loop - but we all know
O(n^2) is bad. So I am looking for something like ArrayList.ToArray(),
or Matlabs A(:).
