How do I get the 'shifted' character of a certain character, for example, I pass it "2" and it returns "@"...

I want this to be independant of the system, so if someone has a keyboard with the @ not above the 2 but the 4, it returns the @ with the 4...

Anyone has an idea instead of writing a huge function or using a textbox and simulating keypresses (I'm using this for a fullscreen DX game, so no controls are used at all)...

Thanks,
