Question

My C++ application stores some common user data in %CSIDL_COMMON_APPDATA%\Company\Product. I want to make sure the Users group has write permissions to this folder which on Vista it does not. How would do I do this?

Answer 1

Figured it out myself using ATL…

CDacl oDacl; AtlGetDacl(strFolder, SE_FILE_OBJECT, &oDacl); oDacl.RemoveAces(Sids::Users()); // Remove existing 'Users' access oDacl.AddAllowedAce(Sids::Users(), FILE_ALL_ACCESS, CONTAINER_INHERIT_ACE | OBJECT_INHERIT_ACE); AtlSetDacl(strFolder, SE_FILE_OBJECT, oDacl); 

Of course my real code contains error checking.
