I have some question’s related to keyboard scan codes.
I have multimedia keyboard. which has some extra keys other then normal
keys. I have scan code list of these multimedia keys in the form of SET1
Make/Break and Set2 Make/Break. my first question why there are two
set(SET1 and SET2) of scan codes ?and why SET1 is not sufficient?
I can see the scan code of multimedia keys using lParam parameter of
" LRESULT CALLBACK KBHookProc(int Code, WPARAM wParam, LPARAM lParam) "
procedure. when I tally these scan codes with the scan code list then I
found that they are equal to SET1 of scan codes. some of these codes are
equal to charecter’s(e.g.‘A’,‘B’) scan code. so same scan code for two key
on same keyboard. my second question is how I distinguished between those
keys?
Thanks and Regards,
-John
