.net - Difference Between New TcpClient(MachineName, Port) And New TcpClient(new IPEndpoint?

Mar 31, 2011

I have a .Net program that has to run on a cluster of server 2008. To find out the right IP I resolve the dns by GetHostEntry(VarDefinedInfConfig).AddressList(0)

but when I am converting my old code (this code picks the wrong IP) dns.GetHostName().AddressList(0) => this returns a virtual IP and not the right one.So I changed my TcpListener to (dns is parameter from config)Dim listener As TcpListener = New TcpListener(New IPEndPoint(Net.Dns.GetHostEntry(dns).AddressList(0), 8001))
listener.Start()

VS 2010 Socket And TCPClient ?

Jun 8, 2012

I am making a contact management program that works like a chat conversation. First, the client connects with his/her name and says: GIVE_INFO. Then, the server sends the client's info that it gets from a csv. Finally, when the user makes all desired changes, the client "tells" the server the info separated by commas and the server replaces the information in the old csv with the new info.So, the program worked for 2-3 times then all of a sudden when I made some changes it stopped working[code].......

VS 2010 TCPClient - Program Locks Up For A Few Seconds?

Dec 21, 2011

I am making a program to test whether or not a host is online, assuming that host has blocked methods such as ping and netstat -t etc....

So I decided to try and connect to it, but the thing is every limitation I have set doesn't work. The program locks up for a few seconds (which I don't want in the first place) and I cannot terminate the client after say, 100ms of trying to connect.

[code]...

I have tried client.ReceiveTimeout but that didn't speed up the process, still takes the same amount of time for the program to respond.How should I go about testing if the server is up now? Or is there a way where the program wont lock for a few seconds as it does with the TCP method.

VS 2010 Compiler Creates New Variable Automatically When Use If Statement Without Strictly Declared Variable?

Jan 10, 2011

Say that i have the following code that parse about 20k records from the DB.

Code #1

vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While

And then another code which does the very same thing but it seems to be a little cleaner.

Code #2

vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While

This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?

Enabling SSL With TcpClient?

Mar 2, 2009

So how does one turn SSL on in System.Net.Sockets.TcpClient with VB.NET code?

Turning it on in System.Net.Mail.SmtpClient is easy, you set the .EnableSsl property. I cannot find a corresponding property in TcpClient. It's probably buried somewhere.

How To Specify An IP Address For TcpClient To Use

May 16, 2011

During development, we usually use localhost as the hostname, like the following

Dim serverListener As New TcpClient("localhost", 8585)

I want the user to be able to enter their IP address via a TextBox instead, like

Dim serverListener As New TcpClient(textbox1.text, 8585)

However, this is not working for me.

Tcplistener / Tcpclient Over LAN

Apr 22, 2012

I am creating an application that will be talking over the LAN (and eventually, WAN) which uses the Tcplistener and Tcpclient objects.Now, I have this working absolutely fine locally using the loopack address although when I change the IP of the listener to 0.0.0.0 (listening for all IPs) and the IP in the client application, to the IP of the server, it throws an exception when connecting. The client says something along the lines of the the server has rejected the incoming connection. So i disabled all firewalls temporarily but I still have the problem.I have ran netstat on the server which clearly shows that it is listening for an incoming connection on 0.0.0.0. [code]

.net - Working Of Tcpclient Sockets In .net?

Jun 2, 2011

I have an application in vb.net which will connect with an hardware device and test its functionality. The hardware device basically spits out data continuosly through Ethernet. That is it recieves some data via com ports and spits out the processed data via ethernet.So my application does both. Thats pretty much the entire app.My problem is i am using tcpclient sockets. Now when i connect a tcpclient to the device using

tcpclient.open(ip,port);

Immediately the device sends some data which comes and get stored in the clientsocket. Then i send a command to it ,only then i read the data from the clientsocket using

tcpclient.getstream().read()

at this time the entire data that is the one which flowed immediately when connected to the device and the one that i actually need after passing command is both acquired. This is undesirable. I need the data which i read only after sending the command. So i was wondering if there is any way to clear the tcpclient socket before we do a read. The manual doesnt show any such method.

Communications :: TcpClient/Listener ?

Jan 16, 2010

I'm having a hard time getting the fundamentals down about these TCP Socket classes.

When you use TcpClient, you can set the IP Address or domain name to connect to the server end of the socket. I see examples that use "localhost" as the first parameter for TcpClient. Is this just a broadcast over the network to find the server that has a TcpListener listening on the dictated port of the second parameter of the TcpClient declaration? With any IP address for TcpClient (I realize that's an option, though), how does "localhost" find the TcpListener server?

Pass A Class Using TCPClient?

Mar 6, 2009

I have been reading the following thread by perito which was resolved with a great deal of assistance from Athiest.[url]...

Using the sample code in this thread I have now created a Client and Server app which is successfully sending messages over a network between two machines.

Now that I am able to send simple text messages I would like to progress to my intended pratice of sending more complex information between the machines. I have already written a program which generates and stores data with a class which I use as a data type. I would like to be able to pass this class from one machine to another.

Sending A String Using TcpClient?

Sep 13, 2009

My tcp client has made a connection to the server script! Now that it has connected, how can it send a simple string? I do not know what any of the overloads for the .Client.Send method even mean, or how to use them. I already have a system set up on the server side to parse the string when it is received on the server side, but I have no idea how to send a simple string to it.

Get Accurate Amount Uploaded With TCPClient

Jan 3, 2011

I'm using the code below to send large strings (500kB) to a server. I'd like to show the upload speed and in order to do that, I need to calculate the amount uploaded every second.

In a Timer that fires every second I get the BytesUploaded, divide it by 1024 in order to get KiloBytes (kB/s) and show it to the user. Then I set BytesUploaded to 0 and one second later do the same process.

The uploading is done asynchronously and the size of the data is added to BytesUploaded at once. This means that BytesUploaded is not being updated in a constant flow and has a totally different value almost every second.

0
512000
0
0
