Before we started the project we checked and found strong typed datasets the most fitting solution, Though some people strongly advised against it. I works fine in a different area of my project (With mysql), So I don't know why people dislike it so much, But I have little experience with databases so I guess you have your reasons. Anyway, For my specific problem I will do as you suggested and further my research in to the DALs. Thank you very much you really helped me. Sincerely yours Y.R.

Microsoft tends to do the hard stuff and leave the easy stuff to you. (Which is better than the other way around.)

I have one cpu and one internet connection (750 k). But it should not matter because when one is downloading file from a server that is slow multiple http connections to this server will raise the overall speed like many existing download accelators(e.g. Get Right, DAP, etc..) I think the problem is in my multithreading part. Sincerely yours Y.R.
