Hi,

Try creating a new Form and setting the FormBorderStyle property to
FixedToolWindow or SizableToolWindow.

In an event handler for a Button.Click event, for example, open your Form:

private void button1_Click(object sender, EventArgs e)
{
   TinyForm form = new TinyForm();
   form.Show(this);
}
