Question

I have a problem with my forms. I have a parent and child form. In child form I have a button. I want to close parent window using button and create new instance parent form and shows new parent form. Anyone can help me? I tried

private Form1 m_parent;

        public Form2(Form1 frm1)
        {
            InitializeComponent();
            m_parent = frm1;
        }

and after that m_parent.Close(), but only what I got is both forms was closed and this is it. After m_parent i create new instance but my application was closed.

Answer 1

calling parent functions from child form

Main frm = new Main();
frm.Show();
frm.Activate();
this.Hide();

This will hide the current form and shows Main form.
