I need a TCP Client - Server application that is able to transfer byte streams for chat, file transfers and so on, made in Visual Basic .NET 2008 or above. The GUI is not a problem; you can just dump random things everywhere; I'll fix them myself. The following features are required: - TCP based ONLY - A-Sync file, text transfer - Theoretically unlimited clients - Server has no controls, other than "restart" and "start/stop" - Client and Admin control are separate from the server and each other - Chat (chatroom + one on one), file transfer, system transfers (auth, notifications, ads) - Rich Text Chat Log - ability to include colors, italics, underlining and bolding - Rijndael on-the-fly data encryption + checksums - Ability to internally store files as a stream (and thus not saving/dumping contents to a file) I will need the source code. If you need, I have a base that I've been working on for a while, but recently ran out of time to develop, which includes the TCP base, encryption algorithms, save file to stream and using it in the program. If you've read all this, please send me a PM after you bid, with the content as "I gots it" to make sure that you're not one of the bid spammers (: Oh, you need to speak a decent degree of English.

I can rewrite the code in C# 2008, using Microsft SSL library to encrypt (TLS 1.0 most secure protocol) and support multithread file transfer. I can provide you the source code.

Sir, As per your requirements, here are my initial inputs for the project on the higher level: 1> We can create a WCF application containing a client and server solutions. 2> We can keep TCP as the protocol for communication and expose endpoints on the server with TCP addresses. The end points can be exposed using service hosts. 3> We can use these server endpoints on the client application to send and receive responses. All the above activities are part of WCF but need proper implentation and knowledge which is my area of expertise. Another advantage with me is my fluency with english. I have a good exposure of american english which you will realize after we talk. Although I a new member on freelancer.com, I am looking forward for your interest in working with me. Thanks, Naveen
