downloading developed updates

Hey all, ok my prog is going to be made up of 1 exe = main app and loads of dll's each, i am thinking about updating the application and in my splash screen i will have a version checker which basically checks the application version with a web service at our office, if numbers match then no need to download and app opens, if numbers dont match then i would like to download from our server certain files, an index of updated files will be held in a database, these files will just be downloaded to there installation location and overwritten so the application gets updated. My main question is how would i go about transfering the files.....

Many Thanks

Carl

I haven't personally tried this block but there is an ms application block for an updater:
