How to Remove the Readonly attribute of a File MFC

Question

In my MFC application I have set the read only attribute on a particular file. I have done this by using the SetFileAttributes() function. At some point I have to remove that attribute of that file again.

Can anyone explain how to do this?

Don't you just GetFileAttributes, mask off the flag (flags &=~READ_ONLY) and SetFileAttributes again? — Rup, Oct 27 '11 at 09:26
Thanks For the Comment... but not clear... Will u please explain (if u don't mind an example will be more helpful) — JijeshKV, Oct 27 '11 at 10:26
I assumed that wasn't too much different from what you were already doing to set it read only in the first place! But glad to see Serge has helped you - you should click the tick next to his answer since it solved your problem. — Rup, Oct 27 '11 at 17:06

Use SetFileAttributes again to reset the flag:

SetFileAttributes( pszFilename,  
                   GetFileAttributes(pszFilename) & ~FILE_ATTRIBUTE_READONLY);

GetFileAttributes() may returned many other flags that the SetFileAttributes() function doesn't understand, is that safe? Will those extra flag be ignored? – Alexis Wilke Dec 29 '12 at 04:58
2nd call has a typo, File not Files :) – paulm Mar 11 '13 at 17:23
@paulm: Feel free to fix it. That's why SO is a wiki! OK, did it. – Serge Wautier Mar 12 '13 at 09:33

I'd love to, but it says changing 1 char is not enough and won't accept the edit. – paulm Mar 12 '13 at 12:37
