Events heirdom

[Mateusz [PEYN] Adamus]

Hi

I have 2 forms, like this:

Form2 : Form1

On Form1 I have a button1_Click event.

On Form2 no event is set.


When I Click button1 on Form2 the onClick event is fired two times. I
figured that its because Form2 is made out of Form1, so program actually
has two events, one on Form2 and second one on Form1.


Am i correct?

How can I prevent from firing onClick event second time?


bets regards

PS: How do you say in english something like this -> Form2 : Form1 ??
I got heirdom from some web dictionary but I'm not sure if this is
correct

Form2 inherits Form1 (the noun will be 'inheritance').

When I Click button1 on Form2 the onClick event is fired two times. I

It's a very strange behavior. All inherited stuff is not duplicated, if you
have an event in a base class, you will still have the same event in the
derived one. Just make sure you don't add a handler for button_Click in
Form2 to raise the onClick event if Form1 already does so.
