Passing user defined types

I`m want to pass a user defined type from a class to a form, but I cant get it to work. Any ideas?

This is what I've got:

Code:

---

'header.bas

Public Type param_struct
  lngIdent As Long
  intDataLength As Integer
  lngRecOverrunFlag As Long
  lngRCVFIFOLostMsg As Long
  typData As DataValues
  lngAckOverrunFlag As Long
  lngXMTAckFIFOLostAcks As Long
  lngXMTRmtFIFOLostRemotes As Long
  lngBusState As Long
  lngErrorState As Long
  lngCan As Long
  lngTime As Long
  End Type

' Class

Option Explicit
Public Event CanEvent(ByVal node As Byte, ByRef param As param_struct)

Public Sub Canread()

'code...

RaiseEvent CanEvent(node, param)

'code...

End Sub

'form

Public WithEvents Can As Class1

Private Sub Can_CanEvent(ByVal node As Byte,byref param as param_struct) ' event handler
end sub

---

Cheers

Ditto!

I'm having the exactly same problem. All I can get from VB is

"Compile Error: Only public user defined types defined in
object modules can be used as parameters or return types
for public procedures or class modules or as fields of
public user defined types."

However, this is exactly how I, and Rick, have been trying to go at it (at least as far as I can see).
