I am having problems figuring out how this should be done.. for instance if part 1 is checking every minute by using a timer if parts 2 - 4 haven't completed after part 1 has notified them the first time it might try to notify about the same records again

Why do you stream.Write()?

Also, you don't say where the errors occurred

public static Bitmap BytesToBmp( byte[] b )

    using ( MemoryStream ms = new MemoryStream(b , true) )
