ReDim a type

Hi there,
I'm using type to store data in my VBA code. I start with the usual declaration:

Code:

---

Type BeamType
        TotNo As Long
        No(200) As Long
    End Type

---

I then assign a variable to this type:

Code:

---

    Dim Beams As BeamType

---

How do I change the array size in my code though, I tried ReDim like:

Code:

---

    ReDim Preserve Beams.No(1 To 20) As Long

---

But that just produces an error.
Any Ideas?

try this and see

Code:

---

Option Explicit

Type BeamType
    TotNo As Long
    No() As Long    ' --------
End Type
 
Sub test()
    Dim i As Long
    Dim Beams As BeamType
ReDim Preserve Beams.No(1 To 20)
    For i = 1 To 20
        Beams.No(i) = 10 * i
    Next i
    For i = 1 To 20
        Debug.Print Beams.No(i)
    Next i
ReDim Preserve Beams.No(1 To 30)
    For i = 1 To 30
        Beams.No(i) = 10 * i + 1
    Next i
    For i = 1 To 23
        Debug.Print Beams.No(i)
    Next i
End Sub
