What is reflection, and why is it useful?
I'm particularly interested in Java, but I assume the principles are the same in any language.

So, to give you a code example of this in Java (imagine the object in question is foo) :

email itself is hosted on the same server, so it gets sent there instead and ignores the MX record.

Ok, so, my visual studio is broken. I say this NOT prematurely, as it was my first response to see where I had messed up in my code. When I add controls to the page I can't reference all of them in the code behind. Some of them I can, it seems that the first few I put on a page work, then it just stops.

I'm trying to pick up ruby by porting a medium-sized (non-OO) perl program. One of my personal idioms is to set options like this:

$opt_v && print "something interesting\n";
