ActiveX wrapper with Callbacks

I am trying to write an ActiveX control in VB that wraps a 'c' based dll. The basic requirement is for a callback 'event' from the dll to generate an 'event' from the ActiveX control.

The problem I have is that to use callbacks and the 'AddressOf' operator the callback code must be in a standard module within the ActiveX component. However, the RaiseEvent command can only be used in a class or usercontrol module and I can find no way for a standard module to communicate with a usercontrol module within an ActiveX component (other than polling).

I am sure there must be an easy way around this but it has so far escaped me. Any suggestions appreciated.

The .dll obviously raises an event. Why not declare it withevents in the class module?
