Ok, my Syntax is wrong but if i understand right 'DeviceIoControl' is already define ... so what do i miss :?:
i have try to include LIBs

Code: Select all

libpaths=c:\harbour\comp\mingw\lib
libs=kernel32
libs=ntoskrnl
libs=win32k 
libs=ntdll
but it does not help.
any Idea :idea:


hole Articel is here

have fun
