You can make a static class in a new FormManager.cs file, every time you show or hide a form use this class.
Example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WindowsFormsApplication1
{
    public class FormManager
    {
        static FormManager _instance = null;
        private Form1 f1 = new Form1();
private Form2 f2 = new Form2();
        public static FormManager Instance
        {
            get
            {
                if (_instance == null)
                    _instance = new FormManager();

                return _instance;
            }
        }

        public void FormOne(bool flag)
        {
            if (flag == true)
                f1.Show();
            else
                f1.Hide();
        }

public void FormTwo(bool flag)
        {
            if (flag == true)
                f2.Show();
            else
                f2.Hide();
        }
    }
}

Sample code of the form

FormManager.Instance.FormOne(true);
