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 completely). 

The list is copied into the file object.
