[RESOLVED] Converting a keystroke to UpperCase?

I've asked this question before and got the answers I needed, however, I'm using VS 2012 and I'm not sure how to resolve this but I need to convert each character I type into UpperCase. Not sure which event to use. I've tried the KeyPress, KeyDown and TextChanged events. I've noticed that the KeyAscii argument isn't available, which is what I'm used to seeing.

Thanks,
