And, is there any good way to join these informations to be an 32 bit integer? at this time i convert the 32bit integer into binary string, process it's with array segment to get all informations then convert them to integer, to build the 32bit integer, i join all information value into binary string (yes, 32 bit of char ;p) join all of them then convert to integer. I know my way is sucks and too far away from COOL thing ;p, i think there are cool way to do this!.
