Hide form and show

Question

What I'm trying to do is when form2 is opening making the parent form Hide. That is none issue but when form2 is closed I want to Show the parent form again.

   this.Hide();
   ReadFrom form = new ReadFrom();
   form.ShowDialog();
   this.Show();

That only flash quickly the parent & it still stays on the screen (windows form not wpf)

Answer 1

1st form:

public partial class Form1 : Form
{
    public Form1() { InitializeComponent(); }

    private void button1_Click(object sender, EventArgs e)
    {
        ReadFrom form = new ReadFrom();
        form.Owner = this;
        this.Hide();
        form.ShowDialog();
    }
}

2nd form:

public partial class ReadFrom : Form
{
    public ReadFrom() { InitializeComponent(); }

    private void ReadFrom_FormClosed(object sender, FormClosedEventArgs e)
    {
        this.Owner.Show();
    }
}

Answer 2

I swear to god I don't know how but I tried your answer Toni & Maciej Los . Both didn't work. But it guided me. I don't know why this works now but it works (might have changed a property by mistake & now it works, dunno) the code:

   this.Hide();
   ReadFrom form = new ReadFrom();
   form.ShowDialog();
   this.Show();

Sorry for the inconvenience guys.
