Re: NetUserEnum

[Stefan Leichter]

Hello,

some things me think are not correct.

1. you fill the values into the memory pointed by data but how is data passed 
back to the caller of the function ?
2. the string you like to pass back for some fields of the USER_INFO_20 is 
ASCII but it must be UNICODE (change char -> WCHAR).
3. the above string  is not terminated (add ,0)

Note: For 2 and 3 you need to adjust the count of memcpy or better use 
lstrcpy[n]W.
