I've recently used Ideablade to create an "Attachment" section for our program.  Allowing users to upload and download to the database any file they want.  It works great for small files.  But the larger the file gets the longer the pause is (naturally), and I was told to not restrict the size of the files because we don't know the file sizes the users will be uploading.  For some larger files the program looks frozen.  Don't get me wrong I think the transfer rate is good, but in my implementation the user can't do anything until the SaveChanges has completed. 

 

I thought maybe of using a progress bar to indicate how much of the attachment is transfered and that the program isn't frozen.   Is this possible?  Is there anyway of finding out that say a block of 128, 256, 512 or even 1024 kb has been transfered?  Which i could then use to increment my progress bar.

 

Or should I just go back to the designer and say we have to cap it?  Should I try an Async style save which I read about on these forums.
