    Passing through forms?

    i can open another form in the main form but i want when the 2nd form is opened the main form will be closed

    Code:
    if (OgrenciGiris == null)    //main form is frmPersonelGiris 2nd form is frmOgrenciGiris
                       {
                           PersonelGiris = new frmPersonelGiris();
                           PersonelGiris.Close();
                           OgrenciGiris = new frmOgrenciGiris();
                           OgrenciGiris.Show();
                       }
    how can i do that?

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

    Code:
      PersonelGiris.Hide();
    as opposed to closing it.

            private void button1_Click(object sender, EventArgs e)
            {
                 if (OgrenciGiris == null)
                       {
                           PersonelGiris = new frmPersonelGiris();
                           PersonelGiris.Hide();
                           OgrenciGiris = new frmOgrenciGiris();

                           OgrenciGiris.Show();
                       }
             }
       }

    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.

    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.
