Flags constants and new version
-
I was responsible for this horror: Version 1.0 I had the following:
const DWORD ACCESS_NONE = 0;
const DWORD ACCESS_VIEW = 1;
const DWORD ACCESS_MODIFY = ACCESS_VIEW | 2;
const DWORD ACCESS_DELETE = ACCESS_VIEW | 4;
const DWORD ACCESS_ALL = ACCESS_VIEW | ACCESS_MODIFY | ACCESS_DELETE;
const DWORD ACCESS_ADMIN = ACCESS_ALL;I needed ACCESS_EXECUTE in the next version of the software. So I declared:
const DWORD ACCESS_EXECUTE = 8; //Execute may not need view
const DWORD ACCESS_ALL = ACCESS_VIEW | ACCESS_MODIFY | ACCESS_DELETE | ACCESS_EXECUTE;const DWORD ACCESS_ADMIN = ACCESS_ALL; Where is the horror? We promised the user that old databases and files will run without any changes.

the check:
if ((access & ACCESS_ALL) == ACCESS_ALL)
will fail on (even ACCESS_ALL) old files. :)
