Is there any possible way to transfer Pokemon from Pokemon Diamond to Pokemon Black with only one DS?

I know there are some Wii games you can transfer Pokemon to from Diamond, is there any way to bring them from there to Pokemon Black? Or any kind of way to set them somewhere online on the one game, and get them to the other via Wi-Fi?|||i used to send them through the internet wifi thingy, but its possible that way that someone else could come steal your pokemon :(|||Nope, there is no other way for you to send Pok茅mon form "Diamond" over to "Black" with only 1 DS, the only option you have is to find someone you trust and trade the Pok茅mon you want sent over to them to their Diamond, Pearl, Platinum, HeartGold or SoulSilver game and then they can send them to their "Black" or "White" game and then they can trade them to your "Black" game.|||That isn't true Matt. Why would you trade to a friend when you can just borrow a friends DS? No you cannot poke-transfer with one DS sadly.|||I wish. Don't think that pokeranch thing works with black, but I could be wrong.|||Nope|||Yeah, what Matt said. That's what I have to do :]
