In the code you posted, convertToInt32U function is nowhere to be found. Do you have any idea where it is?
kl tehPosted Mar 19, 2009, 6:49 AM
anyway,i try looking for it at another class/function (not the main function as ) but i dun think i can find it
p/s:if u wanna have a look at the code,do pm me :)
and sorry for my bad english
