    ACtually it's not that hard:
    Code:
    Red = lngValue mod 256
Green = int(lngValue / 256) mod 256
Blue = int(lngValue / 65536)
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
