Redim Preserve - strange Subscript out of Range case

[n3olcsatok]

Hi All!

I was trying to use a dynamic, 2 dimensional array. I know full well that only the last dimension can be sized, so I used the following code:

ReDim pFields(1 To 2, 1)
pExtent = 1
Do While Not IsEmpty(vTable.Cells(pExtent, 1))
   ReDim Preserve pFields(1 To 2, 1 To pExtent)
   'other stuff
   pExtent = pExtent + 1
Loop

The strange thing is, I get a Subscript out of range error upon first execution at the ReDim Preserve, yet in another bunch of code this worked perfectly. Do you have any ideas what may have gone wrong?

Declare the array as Dim pFields() to start with. Any good?

First redim should be:

ReDim pFields(1 To 2, 1 To 1)

All depends on Option Base directive. If you have 0 or this directive is omitted, then your second dimension is "0 To 1".

Ah forgot to add, pFields and pExtent are private elements of a class:

Private pFields() As String
Private pExtent As Long

Code is in a function in the same class.
That's why this whole thing seems strange.

First redim should be:

ReDim pFields(1 To 2, 1 To 1)

Geez. Thanks!
