how do I extract a style from a DWORD style

Can someone please tell me how to extract a style or value from a DWORD style.


DWORD dwAttribute = GetFileAttributes( szSomeDirectory );




//FILE_ATTRIBUTE_READONLY from say dwAttribute

I want to know if the file is read only

say ...
if( dwAttribute == FILE_ATTRIBUTE_READONLY )
//.... of course this will not work as there are other attribs has other values...

thanks in advance..

I did it this way and it seems to work...

Code:

---

DWORD dwAttrib = GetFileAttributes( strTemp );

if( dwAttrib == 0xFFFFFFFF ||
    dwAttrib == (dwAttrib | FILE_ATTRIBUTE_READONLY))
{
                MessageBox("Destination 1 write test failed");
                ShowProgressCtrls( FALSE );
                return;
}
