I have built a rating server control. Whats the best way to ensure one vote
per person? Check IP Addresses and allow 1 vote per IP address or via
cookies?

Hello Showjumper" dfgkjhdf,
IP Address doesn't work because of proxy servers. I have to say that e-mail
address is the only way I can imagine it workign well.
Thanks,

IP addresses cannot be relied upon to be unique because of proxy server &
such.
The only reasonable way to be sure is to create an authentication system.
People sign up, get a user name and password, then they log in and vote.

How is MSDN handling it? At the end of the articles, one can vote and if you
try to vote twice a popup appears.

Pretty sure they are just setting a cookie to do that.

Some sites pass a cookie once you vote. Of course if you erase the cookie,
you could vote again so it isn't reliable.

My preferred design is to have a table with a single row that contains

The existence of the row will serve a) to allow the system to bump any
other user who wishes to connect, and b) to inform such users of the
name of the currently logged-on user.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
