You should set the BTNOK event handler in form1's class to public instead of private, this will enable you to call it from form2's class.

Then the code in form 2:

private void BTNYES (object sender, Eventargs e)

Form1 form1 = new Form1();
form1.BTNOK(sender, e);

private void BTNYES (object sender, Eventargs e) Form1 form1 = new Form1(); form1.BTNOK(sender, e);

This should do it, but uses too much resources for the purpose, I think.
