Modal form doesn't appear in tray until minimized and owner-form is clicked once. How do I make it appear?

问题

("Click on owner-form" doesn't count. :))

I have:

public partial class Form1 : Form
{
    Form2 frm2 = new Form2();

    public Form1()
    {
        InitializeComponent();
        frm2.Owner = this;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        frm2.ShowDialog();
    }
}

回答1:

Just change the owner setting from

frm2.Owner = this;

to

frm2.ShowDialog(this);
