[RESOLVED] here's one for the purists

[biege]

I have a button click event handler where an array QQ gets populated with Single values & I open a new Excel workbook & try to dump the values of QQ into it :

Private Sub button_Click()
 
Dim QQ() As MyType
ReDim QQ(3)
 
'...
'QQ gets populated correctly here...
'...
Set oXLApp = New Excel.Application
oXLApp.Visible = True
Set oXLBook = oXLApp.Workbooks.Add
Set oXLSheet = oXLBook.Worksheets(1)
 
oXLSheet.Range("A1:E9").Value = QQ
...
end Sub

where MyType is defined as

Private Type MyType
    lZero As Single
    lOne As Single
    lTwo As Single
    lThree As Single
End Type

I get compiler error :
"only UDTs defined in public object modules can be coerced to or from a variant or passed to late-bound functions"

What does this mean ??
I tried changing the button_Click() subroutine from Private to Public, but still get the same error. I would much rather understand the source of the problem than try to blindly correct it.

thanks,
