This is normal for a dispinterface. Dispinterface methods are not
real methods, they are simply contracts on what DISPIDs are valid for
IDispatch::Invoke call and what parameters should accompany each
DISPID.

That is good to know, however the compiler is complaining that the
onTriger() does not exist on that interface.

Of course. That's precisely what I was saying.

The offending line is hr = pConnection->OnTrigger( Line, EventType);
which is located in the Fire_onTrigger method from the
CProxyICTIEvents class, and this method was generated by the "add
connection point" wizard from Visual Studio.

The code is written as if for a regular interface, not a dispinterface.
Did you make ICTIXEvents a regular interface originally, generated the
connection point proxy, then changed it to a dispinterface? Try
recreating the proxy (simply do Implement Connection Point again).

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
