well, let me tell you my aim
I have designed a virtual keyboard with my customized set of buttons. for
every key pressed holding a character, everything is working just fine. As I
mentioned below I'm using the
ord(Key) - ord('a') + ord('A') to convert between lowercase and
uppercase...
I should rephrase my question, I dont want to display @ whenever I press
shift+2, but I want to display whatever key is associated with the 2 key...
for instance in the example you gave, on british keyboards the double quote.
That is why I wanted to know if there is a relation between 2 and the key
above it...
Thx

No.
Problem is, those uppercase characters are very keyboard-dependant.
If you have a British keyboard, the uppercase 2 would be a double
quote and not the @ sign. You'd also get other possible results with
other kinds of keyboards. Not to mention a Japanese keyboard here.
Technically speaking, key's don't have an uppercase or lowercase
value. They just have a value. Characters do have an uppercase value
but only if they are letters. There is no uppercase 2.
What you are looking for is getting the layout of the keyboard with
the additional keymapping. If you have the Platform SDK from
Microsoft (which you can download from free anyways, somewhere) then
you can check the different layouts by searching for the
word "keyboard" in this documentation.
With kind regards,
