---

if (OgrenciGiris == null)    //main form is frmPersonelGiris 2nd form is frmOgrenciGiris
                  {
                      PersonelGiris = new frmPersonelGiris();
                      PersonelGiris.Close();
                      OgrenciGiris = new frmOgrenciGiris();

You can't. You'll have to hide the main form as follows:

Code:

---

  PersonelGiris.Hide();

---

as opposed to closing it.

i tried it but i did not work
there is something suspecting me
the

Code:

---

public partial class frmPersonelGiris : Form // the main form is frmPersonelGiris
    {
        public frmOgrenciGiris OgrenciGiris;
        public frmPersonelGiris PersonelGiris;
       
        private void button1_Click(object sender, EventArgs e)
        {
            if (OgrenciGiris == null)
                  {
                      PersonelGiris = new frmPersonelGiris();
                      PersonelGiris.Hide();
                      OgrenciGiris = new frmOgrenciGiris();
                      OgrenciGiris.MainForm = this;
                      OgrenciGiris.Show();
                  }
        }
  }

when i did not write

Code:

---

public frmPersonelGiris PersonelGiris;

---

in the top of the form it did not work
how can i do it?

If you have two forms you want to show one after another, call both of them from your main method. Don't have one call the other, if you close the first, the second will be gone, too.

how? what did you mean in main method ? i want after clicked on a button the first form will closed and the second form will open

PersonelGiris = new frmPersonelGiris();
PersonelGiris.Hide();

Don't you realize what you're doing here? Read through these and try to understand why the main form (which has already been created) does not hide.

Also, note that if you hide the main form you have to manually close it or manually exit the program or it will still be running in the background, not visible to you.

ok i fixed it you are right magos
thanks magos and nvoigt :)
