C#

private void ShowMyOwnedForm()
{
// Create an instance of the form to be owned.
Form ownedForm = new Form();
// Set the text of the form to identify it is an owned form.
ownedForm.Text = "Owned Form";
// Add ownedForm to array of owned forms.
this.AddOwnedForm(ownedForm);

// Show the owned form.
ownedForm.Show();
}
