Well, if you can't translate it into c++, I'm not sure anything I could do would help you.

Solution 1

in c# it will look like

C#

public event MyEventHander myEvent;

private void FireMyEvent( MyEventArg myEventArg  )
{
  if(myEvent != null)
  {
    myEvent(this,myEventArg);
  }
}

I need C++/CLI implementation, I am doing some unmanaged stuff with this, so I am making this question unanswered

@Radhakrishnan: In your question you specifically asked also for a C# solution. So why would you downvote somebody who helped you in your quest for knowledge?
You are not showing good manners! X|

@Espen: I've decided to compensate! Take my 5!
I also wish you all a blessed, successful and mostly Happy New Year!
