Hi!

Here is some code. But the code marked with * below how would that
//Create a delegete
public delegete void MyEventHandler(object sender, EventArgs e);

//Create an event member
public event MyEventHandler MyEvent;

//Invoke the delegete within a method when you need to raise the event, as
the following code demonstrates

if(MyEvent != null)
MyEvent((this, EventArgs.Empty)

EventArgs e = new EventArgs();

if (handler != null)
handler(this, e);

Sorry

I mean these lines.
if (handler != null)
handler(this, e);

Should handler be MyEvent or ?

....and what's to rewrite about this?
What's the actual source, and what's the actual problem you're having?
