 MFC + ATL: throwing an error back to VB


Has anybody got a complete and simple example on how one can generate an
exception from VC++ 6 that will be catched by VB. I would very much

I am trying with AfxThrowOleDispatchException(0,"ERROR",0); but I catch
nothing error in VB.
I have been looking a lot in msdn, codeguru... and I could not find clear
explanation with a complete example throwing error back to VB.

My code in VC++ is straightforward :

STDMETHODIMP CRaiseErrorObj::DivideBy0()


 return S_FALSE;


and in VB :

Sub test()
  Dim o As RaiseErrorObj
  On Error GoTo HandleError
  Set o = New RaiseErrorObj

  Set o = Nothing
  Exit Sub
  MsgBox Err.Description
End Sub

Many thanks in advance,
