Small Program: Detect whether CapsLock key pressed

[English ver.]
       
        Usually the keyboard has a led sign which tells you whether the Capitial key is pressed, but my nb seems doesn't have extra room for it. When I was typing a password, I could realize I was in Captial after many errors. So I write a program with vb to show the status of Captial key. Download here.
        When it is in Captial, an icon will show in the task bar. And if you want to shut it down, just right-click it in Captial. Then choose "exit" to close it.
