Memory Mapped File Test Source

When I use Create file to create/open file used for File Memory Mapping with a
call like:
        hFile = ::CreateFile(lpImageFileName, GENERIC_READ | GENERIC_WRITE,
                FILE_SHARE_READ | FILE_SHARE_WRITE, lpFileMappingAttributes,
                OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
on a second run of application (file now exists) GetLastError should return
ERROR_ALREADY_EXISTS like it does on Windows XP SP2.
See attached Test Application
