I didnt use Win Vista yet so I dont know if the coding for WinXP would work for Win Vista.
I have few questions:
1)Is there a code to find out what windows is the user using? (XP or Vista)
2)Is Registry the same? Can a program that work with WinXP work with Win Vista's Registry without any additional codes (something to get privialge maybe?)
3)what else should we care about if we're making a program to run on both WinXP and WinVista?

thanks for your help
