Help with ODL

Hello.
I'm trying to make a TLB for the ITextHost interface. What ive come up with compiles OK, but when i do the "Implements ITextHost" line, vb isnt letting me define the functions of the interface. Any idea?

It seems the functions defined in the TLB must return HRESULT. With that said, how is a function supposed to return a long and a HRESULT?

EDIT:
Well, this in ODL:

Code:

---

HRESULT TxGetDC([out, retval] long* hDC);

---

Gives me this in VB:

Code:

---

Public Function ITextHost_TxGetDC() As Long
End Function

---

So im gonna try and work with "[out, retval]" and see if i can get this thing to work.
