I suggest Ign.com, gamespot.com, or supercheat.com
Some codes don't work though, if the code has D2000000 00000000 then it will work
there is also www.gamewinners.com it has HEAPS of cheats 4 Pokemon diamond and pearl and nearly every single other game as well.
Pokemon Diamond Cheats are codes that help you throughout the game. Here are some of them: http://cheats.ign.com/ob2/068/707/707323.html
