Is there no one(user/moderator) who can help me?
You are telling that
the #1 programming and web development help community on the internet
I don,t think so...
Displaying a video while
uploading doesn't quite make sense unless you are using a clientside application. While the uploading bit probably would deserve to be in this forum, the idea of displaying it while uploading makes it more worthy of a C# or VB.NET forum. I'm not saying you'd get better response there. I'm not a client application developer, so I don't know all the client side tricks that could be invoked easily. But it seems to me like you need a program that does two things:
1. Splits a (movie) file into chunks.
2. Plays said file.
On the server side, you need:
1. some thing that accumulates the chunks and can recombine chunks back into a file.
It might benefit you to have some sort of sanity check on both sides (checksum or CRC maybe?... or hell maybe the SHA-1 hash function).
Beyond this, things could get kinda interesting, but it's not really worth getting into detailed hypotheses unless you know where to go with it. For instance, how to play the movie? Do you just hand it off to Windows Media Player, or are there some components you could create/invoke to do something similar? My guess is probably (I know java has some movie handling components, so why not .NET??), but at this point all I could do is guess.
