I will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients canīt work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.

View 1 RepliesI need to transfer files from one server to multiple cients (using the internet) in the fastest possible way in .NET . What are the different types of transfer protocols which can be used in .NET or VB.NET so that the files are sent in a very short time ? I have tried using FTP, but that is slow because it requires authentication, handshaking etc. What i want to know is the options which we have in .NET for sending files in the fastest possible way between a server and multiple clients.

View 5 RepliesI'm studying how to use Visual basics 2010, and I have been asked to create a program that transfers a audio file to one machine, then plays that file when it receives it on the other machine. I have made a basic file transfer, but when I install it onto a computer, the server crashes for some reason. But it will work on some computers. Here is my code for the server:
I also have to make the program so that the client can click a button and then it will play a preset audio file. (example: User clicks button to play a fire drill)So to sum it all up, The server app goes onto the computer that will be playing the audio and the client app allows you to send audio files to it and play

Is the FTM available for .net users to use on our web solutions or sites?I have some large install files on my site that the regular download will quit in the middle.the ftm at least allows for interruptions.I tried the FTP route, but turns out most users out there have no idea what ftp is. I saw a library that eluded to IDownloadManager, but I wasn't sure if this was the same thing as the ftm.

This works perfectly for ASPX files and their .vb code behinds. When we try to transfer .DLL files, they show up on the server as 0 bytes, and sometimes actually transfer. The problem is that, despite being the same size as the original, they act as if they are corrupt.
1. How much load or data size our custom encryption/decryption algorithm can handle? E.g. what's the limit of file size that normal encryption/decryption algorithm supports.
2. What's the best way to use encryption while file transfer via internet?
3. Where and when encryption and decryption has to apply while uploading and downloading content from internet(Hosting on client or server machines)?
4. What type of algorithms suites for above approaches?
5. How much time it takes to encrypt / decrypt data for 10 MB, 100 MB, 1 GB etc

I'm sort of new to the vb 2008, and I would like to be able to send a file to another computer and save it on the local drive. Doesn't have to be in any certain folder, but just on the c drive. I know for the old visual basic you would use winsock for this, but in 2008, they have removed it. What and how will I do this. There will be no program on the user's computer. This is done all from one computer sending to another with no program listening on it. This computer is on my network with network sharing, so I can just do like a \computernameorIPaddress and open send the file that way.
