procedure SetDACL(const list: TJwDAccessControlList; const Protection: TJwACLProtectionState = apNone); override; overload;
Parameters
Parameters 
Description 
const Protection: TJwACLProtectionState = apNone 
defines which TJwSecurityInformationFlag Flag is used:
  • apNone uses simply siDaclSecurityInformation to set DACL
  • apProtected uses siProtectedDaclSecurityInformation to set a protected DACL
  • apUnprotected uses siUnprotectedDaclSecurityInformation to set an unprotected DACL and let flow the inheritance stream
 
Description

SetDACL sets the DACL of the file object. You need WRITE_DACL rights to set the DACL or the curren token must be the owner. 

If you want to replace an existing DACL completly, you have to first call SetDACL with a nil list-Parameter. This creates a NULL DACL (with everybody has access to it) Afterwards you can set a new DACL to the file. So nobody can hijack the file you should also open the file exclusively and do not use the SetNamedXXX methods. 

New You can also use apProtected to remove inherited ACEs (replace an existing DACL completly). 

The list is copied into the file object.
