You can catch Arceus in Diamond, Pearl, or Platinum.

You have to explain more what game are you talking about Pearl/Diamond/Platinum?
No you can't you can trade it to other versions like diamond,pearl, and platinum version and etc.

The only way I know of is to capture one on a gba game migrate it to diamond or pearl and then trade it to platinum. Sorry if you don't have the gba games or diamond or pearl.
Dialga is obtainable only in Diamond and Platinum. You’ll need to trade him from Diamond or Platinum to get him in Pearl. You’ll find him on the Spear Pillar (top of Mt. Coronet) in Diamond and Platinum. Dialga can only be caught post-game in Platinum.
