Is there any way to distinguish between upper and lower case?

Hi shy2net, first of all thanks for posting your code, if I can adapt it to my application it will save me a lot of headaches.

It's being very useful for me but I can't find a way to distinguish the characters entered in lowercase, the ascii codes I get are always uppercase. I have also tried using the "ScanCode" but since the position of the keys varies based on the region of the keyboard it does not work for me either.

Thanks in advance and excuse my English, it is not my native language.
