Hi All,

I'm I correct that you cannot raise events in the New (or constructor)
procedure?

I believe so.
In order to catch an Event from an Object, you have to have a
reference to the object doing the Throwing. You won't have one
until the Object's constructor has completed.

HTH,

You can raise events in the constructor. The problem is that you have to
1. create the object
2. add event handlers

As "create the object" includes the execution of the constructor, the first
handler can not be added before the constructor has been executed completely.
Consequently, no event handler will be called when the event is raised in
the ctor.

One exception:
1. Pass a delegate to the constructor
2. In the ctor, add the delegate to the event
3. raise the event

But, it's easier to simply invoke the delegate.
 
What about static events?
