QUESTION
I have a connection with TCP / IP. I want a multiple connection. I'm using SimpleTcp. It is very simple and useful for single connection. Unfortunately, I don't know how to make multiple connections with SimpleTcp.
The code below is the one used for single connection.
...ANSWER
Answered 2020-Dec-08 at 13:24EthernetDataReceived is just an event handler that can be used to handle the DataReceived event from any SimpleTcpClient object. You can think of it as a method that may be called by any object from any thread.
Isn't there a problem if data comes from all of them at the same time?
Then the method will be called once per event that gets raised. This isn't an issue as long as you don't read or modify any shared data in the event handler. If you do this, you need to make the method thread-safe which is a topic of its own.
Also, how do I know which server data is coming from?
You should be able to cast the sender argument and check the properties of the SimpleTcpClient:

This is a clip from the sample SimpleTCP Server. The VS 2019 compiles with an error on the line:

QUESTION
So I wanted to make a chat app in C#, I watched a video about it(https://www.youtube.com/watch?v=ve2LX1tOwIM), I completely copied the code for now but when I run the server, Connect the client to the server and send a message from the client what happen is that it infinitely sends the message to both client and server. I am not sure why it does that since the code is exactly like shown in the video I watched. You can see this in my repository.
In case you want to see the code: Client:
...ANSWER
Answered 2019-Mar-24 at 15:28The problem is that you have e.ReplyLine… in both the client and the server, remove that from the client and you code should work.
What is happening is that the client sends a message, which the server then receives and sends a reply to, the client receives the reply and in the case of your code sends a reply to the server, this results in the server receiving the reply and sending a reply to that and so on...
QUESTION
I'm building a program that I want to be able to exchange information with other programs running in another computer. I started using C# and a library called SimpleTCP. The main issue is that is too simple and only send and receive messages. I'm looking for something that I can predetermine functions that one or the other can call from each other. I looked on google and stack overflow but I was unable to find an appropriated subject to study, what should I be looking for to learn this? Thank you
...ANSWER
Answered 2018-Dec-16 at 17:54There is a way but it's little bit different Such programs like this written in tow different languages You can make a center database between the both programs In this situation it's very easy to communicate and receive ,send data You can mysql ,oracl, mariadb or any Database you prefer
QUESTION
I am confused how to add parameters to the DataReceived SimpleTCP event handler.
Here's my coding:
...ANSWER
Answered 2018-Oct-16 at 11:07I assume you use the SimpleTCP Library by BrandonPotter. Please add information about used 3rd party libraries in your Question, as it makes it a lot easier for others to help.
The Message object passed in the DataReceived and DelimiterDataReceived event contains a property TcpClient that is the information you need. Therefore you need no additional parameter.
I think you would better use DelimiterDataReceived, therefore your code would look like this:
QUESTION
I have installed TCP/IP from VS15 NuGet Packeges into my project and in References it is as SimpleTCP, I've rebuild project, but for SimpleTcpClient client; it says:
Suppression State Error CS0246 The type or namespace name 'SimpleTcpServer' could not be found (are you missing a using directive or an assembly reference?)
not sure what can be cause of that, maybe I missed some references or even using.

...ANSWER
Answered 2018-Mar-11 at 18:32Clearly HostText.Text is returning a value that can't be parsed into a long.
This exception is coming from long.Parse, which is really a language shortcut for Int64.Parse, whose documentation states that it will throw this exception if the input string is not formatted correctly.
QUESTION
I am receiving large amounts of data (frequent small messages) from an ITCH protocol server.
My app works well in that all messages are correctly parsed. However, I get mysterious delays when ( as far as I can tell) nothing is happening except code is setting at "ReadByte".
...ANSWER
Answered 2017-Sep-07 at 14:34This delay remained inexplicable to me. However, several answers to similar questions suggested that using raw Sockets would be better.
I replacde all my Stream and NetworkStreams with Socket and now the Socket.Receive() works without any ad-hoc delays.

Install simpletcp
simpleTCP just requires that you specify:.
the mode (local or public) of your server your server can also be bound to a specific IP address
the port of your server
what happens when your server receives data
ip: The IP address that the data was received from.
queue: This is a queue.Queue object. Any data put into this queue will be asynchronously sent back to the socket it was received from. In this case, our server echoes all data it receives, so we just put all received data right back into this queue with queue.put(data).
data: This is the data that the server received. It is a string of bytes. Its type is bytes.
The mode. There are two special modes: "localhost" and "public". They are aptly named --- "localhost" means run the server on 127.0.0.1. Therefore, the server is only visible on the machine on which it is running. "public" means run the server on 0.0.0.0 --- make it visible to anything that can see the machine on which it is running. If mode is not "localhost" or "public", then it is interpreted as an IP address.
The port. For development, pick a high (four-digit) number.
The callback function. This function is called whenever the server receives data.
