Passing ArrayList

I have to forms and an arraylist
when i want to access to arraylist from another form
I cant access arraylist's items .
I define all of them public .
source code is here

You need to have a reference to the form 1 that is already created. You are making a new form1 object, but that isn't the same form1 that opened form2.

In Form2 constructor add in a argument that you can pass in a current reference the form that is creating this form

Code:

---

private Form1 fm1;


public Form2(Form1 myFrm)
{
        InitializeComponent();
                fm1 = myFrm;
}

---

Now, in form1, when you create a form2 object, you pass in a reference of itself:

Code:

---

Form2 fm2 = new Form2(this) ;

---

Thank you very much
