For the record, I am a newbie to API. Anyway, I am trying to use the Win32 API in VB.NET to set NT Security (Administrator ACE) on a remote server folder from within a backup executable I have created. The problem is I am trying to implement my translated version of the NTFS Permission example, at http://www.mentalis.org/apilist/LookupAccountName.shtml, to VB.NET and the code fails at one particular point. (BTW, I have chosen NTFS Permission example because it seems pretty straight forward for a newbie.) I have converted all Longs to Ints and added ByRefs where needed, but the app seems to quit at the AddAce Call (ERROR_INVALID_PARAMETER). Has anyone already converted this code or would anyone have suggestions for a fix?
