Hi,

I'm trying to redim a dynamic multi-dimensional array. However, no matter how I frame the redim statement, it doesn't work.

Sub test()

Dim yabba() As Variant

ReDim yabba(10, 1)

yabba(0, 0) = "a"
yabba(0, 1) = 1
yabba(1, 0) = "b"
yabba(1, 1) = 2
yabba(2, 0) = "c"
yabba(2, 1) = 3

ReDim Preserve yabba(3)

MsgBox (UBound(yabba))

End Sub

From Help:


If you use the Preserve keyword, you can resize only the last array dimension and you can't change the number of dimensions at all. For example, if your array has only one dimension, you can resize that dimension because it is the last and only dimension. However, if your array has two or more dimensions, you can change the size of only the last dimension and still preserve the contents of the array.
So you could Redim Preserve (10, 2) if you wanted to.

You could do this:

Option Explicit
Private Type MyType
    Var1 As String
    Var2 As Integer
End Type
Private Sub Form_Load()
Dim yabba() As MyType

ReDim yabba(10)

yabba(0).Var1 = "a"
yabba(0).Var2 = 1
yabba(1).Var1 = "b"
yabba(1).Var2 = 2
yabba(2).Var1 = "c"
yabba(2).Var2 = 3

ReDim Preserve yabba(3)

MsgBox (UBound(yabba))

End Sub
