I know that that topic may be old to you but I looked at other more-
than-two-year-old topics
related to mine. However, I didn't find them working for my project
at all because its errors return back to me everytime.
The error I have on that project said:
"An unhandled exception of type 'System.EntryPointNotFoundException'
occurred in TestSysaudit.exe
Additional information: Unable to find an entry point named
GetFileSecurity in DLL advapi32.dll."
Here what I have on my project: (Remember this project is under VB
and
don't have a window form because of an executable file that run
everyday). I am appreciate that if you guys help me out on solving
the problem.
