really simple! **SOLVED**

This is a really easy question but I just cant find any Information on this in my books. What does it mean if you write +=

Heres an example:

Code:

---

v.ValidationEventHandler += new ValidationEventHandler (handle_validation);

---

Thanks a lot, Stephan

A += B

is the same as writing

A = A + B

Thats what I thought.

Does it mean the same in my example?

Would that be :

Code:

---

v.ValidationEventHandler =v.ValidationEventHandler + new ValidationEventHandler (handle_validation);

---

Thanx, Stephan

In the above code, it mean that you a subcribing to an event.

If you use this

Code:

---

v.ValidationEventHandler -= new ValidationEventHandler (handle_validation);

---

You are unsubscribing.

Thanx, thats what I was looking for! Stephan
