The ShowDialog method is used to display a form as a modal dialog box, which means that the user will not be able to interact with the calling form (Form1) until the dialog box (Form2) is closed. Therefore, Form2 will appear in front of Form1 and the user will only be able to set the focus to Form2. The MessageBox.Show method will display a message box with the text "Hello" on top of Form2.
