I have done smoe searches on this, aint can't find what I am looking for. I am sure it has already been discussed and everything, but I can't find it..if you know where it is, a link will be fine,,if not here is what I am trying to do.

I am trying to make an updater. I want a person who downloads my game to be able to log into some server, and be able to download an update for the game. I don't want them to have to go to a website and download a file, but rather I want the game to check for any updates from a server, and if there is an update, go ahead and download and install the update...Like EQ I and II, WoW, and the like. thanks for any help you can send my way.
