Create a Windows application that contains two textboxes and three buttons. One of the textboxes and one of the buttons are initially invisible. The first textbox should be used to input a password. The textbox should be masked to some character of your choosing so that the characters entered by the user are not seen on the screen. When the user clicks the first button, the second textbox and button should be displayed with a prompt asking the user to reenter his or her password. Set the focus to the second password textbox.
