Hello,

I have a COM object and a .NET object that need to talk to each other.
The COM object creates the .NET object, but then the .NET object needs to
call methods in the COM object. It appears to me that the best way to do this
would be via connection points.
How do I do it on the .NET side? After decorating with ComSourceInterfaces,
how do I get to the interface? Note that these are not events, so I would
like to call the methods as if I had created the COM object.
Is there a way to EnumConnections?
Is there a completely different way of doing this?

Thanks,
Marius Matioc

As long as you have the interface to the object you could always interogate
the COM objects Type and use the GetMethods()/GetMethod calls the get the
method(s) you wish to execute and then call Invoke on the
Reflection.MethodInfo instance(s).

Thanks for taking the time to answer.
I don't know how to get the interface of the COM object.
After decorating a class with "ComSourceInterfaces", how does one get an
interface pointer to that source interface?
Or is there another, better, way to use connection points in this case?
