However the data takes while to to send be sent back. So in order to get the right information in the right strings I have to put pauses in my code. I have added a timer to my form:

On my timer's tick event I have the following code:

Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
iTick = iTick + 1

Communications :: Socket Behaviour - Created A Client That Can Send And Receive Data Via TCP Sockets

Aug 26, 2010

I have created a Client that can send and receive data via TCP sockets. The objects stored on the serverside are the *exact* same object used for the client. They use the same send and receive protocols.

Now, when i send a string from the server to the client , it does precisely what it should do. However when I send a string to the server.... I do receive the string as an equal length of NULL characters. I run the server and client locally.

Basicly what can influence the behaviour between two completely identical objects performing the exact same task? I wonder if there is some socketflag issue if the TCPlistener.accept function returns a completely different setup then the one I R used to.

(if it is of any interest, the send protocol is asynchronious)

Receive And Send Packets?

.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

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]

See How Much Bytes Did An Application Receive And Send

Mar 14, 2010

I didn't found any performance counter that would monitor an process's/thread's network bandwidth and not just that of an ethernet card.

So I could see how much bytes did an application receive and send.

Did I miss something or is there another way?
