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?

Solution

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?

2nd call has a typo, File not Files :)

@paulm: Feel free to fix it. That's why SO is a wiki! OK, did it.

I'd love to, but it says changing 1 char is not enough and won't accept the edit.
