Network Stream - Send / Receive Text

Sep 17, 2010

I've solved part of the problem, but something I've just realised is the information just isn't getting through and EVERY example I find uses a Console type application and what about us people who don't wanna develop a Console application? I don't but nooooo they don't seem to understand that at MS and put one example which uses exactly that.

Send An Object Over A Network Stream

Oct 18, 2010

So i'm still goofing around with this chat app thing. Current when a user sends a message it sends to all clients connected. The server stores all clients and their IPs in a hash table, so what i want to do is each time a client joins, the server will broadcast the updated hashtable to each client. I know i can make a mess and get the server to broadcast each row of the hash table as a string but i think this way would be cleaner, either that or send the client object instead of the whole hash table.

I'm trying to send a XML serialized class over a network stream

Dim IP As Net.IPAddress = System.Net.IPAddress.Parse(IPAddress)

I always get an error {"Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."} The XMLFile has the xml document in it most of the time and I can go on and everything works but 1 out of every 5 times it doesn't work at all and the XMLFile contains nothing ..

Send And Receive Text Files Amgost Two Computers?

Apr 21, 2012

What code can I use to send a simple text file to someone else's computer and choosing a save location and vice versa from theirs and loading it into a rich text box in their application that they have open, and vice versa? Their application is the same as mine (sort of like how an instant messenger works-except it does not save, send, and load text files like I am aiming for)

2005 - Server / Client RTF Formatted Text Send / Receive

Jan 21, 2009

Instead of the send message text box and message display text box, I have replaced it with RichTextBox for text formatting (bold/italics/underline/font/color). The problem I am facing is when I format the text and click on send, then the text displayed on the message display box (txtMessageHistory) is unformatted. [Code] Rest of the code of client is related to formatting of the rich text boxes that is not relevant to my problem. I just need to transfer the formatted text from client to server and then back to the client the same way and display the message with text formatting.

VS 2008 Network App - Send Message Or Network Package To Some Of The Clients In The Network

Aug 18, 2009

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

.net - Extra Byte In Network Stream?

Feb 15, 2011

I have an .net application with 2 processes, communicating using a network stream.The protocol consists of a set of commands, some with parameters, which are sent through the stream to the server. The server processes the command, and sends a response.

The protocol for one of the commands looks like this:

[code]...

Usually, this works fine. Very rarely (probably once every few millions of calls), The reading side gets the wrong values. I added code to trace the values sent and received. This shows that occasionally, the reading side gets two extra bytes, with the value 0, which was not sent by the writing side. These extra bytes appear in different places, e.g. in one case they were between i1 and i2; in another they were between the first and second byte of s2. Does anyone have any idea where these 2 bytes could come from? I checked my code, and every place that writes to the stream is traced, so it doesn't look like they are actually written to the stream. It might be worth noting that s1 is always 0, in the current implementation.

Stream Video From Network PC Via Webcam?

Jan 18, 2006

I have a little Logitech USB Webcam that I have attached to a laptop and I want to be able to view a video stream from it. I already gathered it will need to be a client/server model...and I probably need to use TCP/IP and/or Winsock (if its still even used)...

how to really approach this application as far as the video capture process? I don't have a need to really record video in any way so if i can just "preview" the video thats fine, although recording would be a neat bonus.

I read into the Windows Image Aquisition libraries and they seemed to be the right thing...but I wasn't so sure about the cross-network half of the equation.

.net - Send And Receive A Large Image Using Tcp?

Dec 19, 2010

I need to send and receive a large image between programs running on different machines within the same network.

I've looked at using upd however ran into problems with the size of the packets and
(after breaking the image into smaller pieces to get past this problem) the number of packets needing to be processed all at once - and ultimately packet loss.

I've also thought of sending the image by storing it in a common file folder and receiving it by using file watcher as a trigger. However, this just adds further complexities in setup where common folders don't already exist.

Assuming I'm barking up the right tree looking at tcp, can someone point me to/provide an example of how to send an image file using it (vb.net would be ideal). Also, are there practical limits to tcp package sizes?

Error Tcp Send Receive Application

Jun 2, 2011

I have created an application which listens for strings being sent to my pc from a remote unit. I now need to add the function of sending strings back to the remote unit on a button press. I've searched for ages to find a solution but I'm not knowledgeable enough yet with vb.net to solve this solution.

I'm getting the error with the line opensock2 = New IO.StreamWriter(client.GetStream) saying its not connected. So I seem to need to pass the connection from the background worker to the button click, or have it somewhere else in the code to make it accessible. [Code]
