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?

Answer 1

Use SetFileAttributes again to reset the flag:

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

Might be worth adding that this method returns 0 if the function fails and you can use GetLastError().
