i have already converted a Visual Basic code into PureBasic code, before asking my question, for whose interested, i show you my results :
VB app :
* size = 27Ko (+ DLLs = 2.87MB)
* RAM = 2 396Ko
* Virtual Memory = 1 496 Ko
-> total = 3.8MB
PB app :
* size = 46Ko
* RAM = 612 Ko
* Virtual Memory = 876 Ko
-> total = 1.4MB
Am I happy with PB ? yes of course

I very like optimization, even when the advantages are small, and i would want to know if the fact of replacing the existing API to write/read "ini" files with PB integrated function would be faster or not ?
I'm using "WritePrivateProfileString_" and "GetPrivateProfileString_" and i saw that PB offers "ReadPreferenceString" and "WritePreferenceString" but need to open/close the file, is it better ?
P.S : sorry for the title, i don't know if it is "are PB functions faster" or "does PB functions faster" :roll:
