How to implement an outgoing interface on a sink object (C++)

 

I have a predefined TLB file, with IS8SimulationEvents wrapper method implementations, for instance: 

inline HRESULT IS8SimulationEvents::S8SimulationReset ( ) {
    HRESULT _result = 0;
    _com_dispatch_method(this, 0x1, DISPATCH_METHOD, VT_ERROR, (void*)&_result, NULL);
    return _result;
}

Using Oleview, I can see the IConnectionPointContainer interface attached to the COM object.

Question:

  • How do I implement the outgoing interface on a sink object, for the client to receive event notification from the COM object

    • Without:

  • ATL
  • MFC

    • This article explain how to implement connections points sources/sinks in plain C http://www.codeproject.com/KB/COM/com_in_c5.aspx

    Probably the whole series of articles "COM in plain C" by Jeff Glatt are more than recommended if you want to understand COM at the low level.

    PD: Lambdasoft Comet is a framework that implement COM wrappers that doesn't make use of ATL/MFC, it is pretty dated but if you want something simple it worth to take a look https://bitbucket.org/sofusmortensen/comet/ or http://www.lambdasoft.dk/comet/.
