So, an admin starts a video on the server, it HAS to play on the server, and also be visible on the client ? They have to be in synch ? The admin can pause the video and it pauses on the client ? How much do you need them to play on the server, and how much control should the server have ?

Thanks for reply Smile | :)

Admin will have the full control and in admin module we will have a video player type UI, in which he can play/pause/stop and that should be visible on the client machine

OK, well, that does make things more messy. If it's not a web based UI ( which I assume by what forum you're in ), then I'd imagine you'd send the videos down to the client, and you'd use a connection ( perhaps through WCF ? ), to send messages to all the clients telling them when to pause, when to play, and from time to time to tell them where the admin video is at so they stay in synch.

It’s a scenario in which the instructor I will play a training tutorial on the system(server system) and the 25 students will be watching on their system(client), instructor can pause, play, stop.

I think I am not able to explain u properly Frown | :(

sorry

its Windows base will be working on Lan

OK, that's exactly what I thought.

OK, well, being on a LAN probably makes it easier to establish TCP connections to pass data around. I still think you want to give everyone a program which can play the video, but that only plays/pauses/stops based on the messages coming from the instructor machine.

yes, client will only have a option to close the file, that's it

So what should i use , Remoting with tcpchannel ?

and how to send the video file,and play it(serialization? )

Christian Graus1-Oct-09 18:46

I would think if you're just on a LAN, you would put the videos onto a shared location and transmit just that file location to the client. To be honest, the amount of network traffic will be so small, that I don't think it will matter what you use to communicate. Remoting will work just fine.

thanks for the help.will be needing ur help in future in these prject. thanks
u means to say the file which is beeing played in the admin first should be stored on the shared folder, and from the client use this file from shared folder and play it ?
for these does we need serialization ?

can u suggest me any references or example for this.

thanks

I have no idea why you keep refering to serialization because it has nothing to do with anything you are discussing. I am saying, if you're on a LAN, then the files can be on a folder that all the students can view. So you send a file path through your remoting connection, and then connect to the file, or copy the file from the central location, just with a File.Copy command.

i want the file which the instructor is playing on the server should be played on the students system automatically

OriginalGriff2-Oct-09 1:48

I think I'd want to do a test first, just playing the video on 25 machines simulaneously. At about 640*350 resolution, you will be streaming about 3Mbyte of data per second from the same server - with network overhead etc, you may get stuttering, especially if you are not on a dedicated or fastish network.

CG did say to copy the file first to local drive that would resolve that issue (k it would create a burst at the start but once playing the only network traffic would be the instructions from the server)

OriginalGriff2-Oct-09 2:44

He did, but then sugested a path they could all get at. If they are held locally then there is no problem, it's a relatively simple MediaPlayer and sockets problem. I just felt that if it was a single copy being read (which is obviously a whole lot easier for configuration and control purposes) then test it first!

You need the path to know from where to copy the file

So server sends network path to video file to all clients, clients use this path to copy the video file from the server to there local drive.
After that clients use the local copy of the video file to play it.

(At least that's how I understood it)

If I was one of the poor sods on the course, that would annoy the hell out of me, particularly if I was paying with my own money:

1) Start training video
2) Wait a few minutes while we copy the file over the network.
3) Video starts.

Copy them all to local HDD: no delay, no stutter, no problem. You can then control it in MediaPlayer (or whatever) via sockets so the trainee does not need to go anywhere near the video file itself.

If the tutor is that paraniod, he can copy them ready in preparation for the days lesson.

Didn't say it wouldn't be annoying Poke tongue | ;-P

I guess it depends on how large the files are.

But even in your scenario the logic still holds, minus the copy part. And provided the tutor put the files all in the same location (something like c:\videos).

I guess the best option here would be:

I have found a good article at http://www.codeguru.com/columns/vb/article.php/c8459__2/ to build a ftp client. But I wanted to get everyone's input on what the best way of doing this in c#.net or vb.net 2008.

What I am wanting to do is have 2 simple classes:
Class 1: Upload...
Class 2: Download...

All I want to pass into the class is the following:
IP Address
Port
Login
Password
Sending/Receiving File Location.

However I need the 2 classes to generate a form to show the user the stages of connection and progression of transmission.

Anyone have any insights on how I can go about this. Perhaps websites that can give me a working model to build from.
I could simply pass the command thru the command prompt but I would rather it be part of the main application and or .net framework if possible.
