Heard that classes in VC have a identifier. Would like to know how this is done, and what it is, a string or something like that. (A Macro?)

(needed for serializing classes, and build somekind of check in it... and i know that it is not nice looking..but what the XXX think i programmed to much Java)

(Please not MFC or STL examples... try to avoid them as much as possibel, MFC due to the fact that u loose the perspective, STL cause it becomes hard to read for others althroug i must say that an apply a very strong mechanism is)
