FireOnChanged in C#

[marioana]

I have an application written in C# that connects through COM to an application written in C++. The problem is that in order to serialize my settings in the main application I need the main application to fire the save event, which will be fired only if I call FireOnChanged (from what I understood from the developers of the main application).
The problem is I am not too familiar with connection points and I don't know how to do that in C#...

Maybe I should give some more details. The idea is that in ATL there is a class CFirePropNotifyEvent (here is the description: http://msdn.microsoft.com/en-us/library/9f0s6xh0(VS.80).aspx ) and I need some kind of wraper to it, or some other mecanism in C# that does the same thing.

Nobody knows how to call a method of CFirePropNotifyEvent from C#?
