.net - Difference Between New TcpClient(MachineName, Port) And New TcpClient(new IPEndpoint?
Mar 31, 2011I 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 2008 Create A Client / Server Chatroom Using TCPClient In Visual Basic
Jan 6, 2010However I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).

Create A Fake Array Using Generics Instead Of Using An Array
Jun 23, 2012This was an experiment to see if I could create a fake array using generics instead of using an array. I decided to try it, because I may use it if I find any advantages to using it over an array. it works, I am just asking for a second or third opinion, have I screwed anything up, or is there an easier way to accomplish this? If I use it, it will be for a 2D game I am creating, and is used to draw the 2D screen graphics, placing an image based on what image identifier is located at what coordinates. The value stored in the fake array is an integer that disignates the graphic to draw and whether it is passible or not, i.e. 0 = a floor image, 501 = a wall image that is impassible (any image number > 500 is impassable) The Class definition:

Enabling SSL With TcpClient?
Mar 2, 2009So 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, 2011During development, we usually use localhost as the hostname, like the following
Dim serverListener As New TcpClient("localhost", 8585)

However, this is not working for me.
Tcplistener / Tcpclient Over LAN
Apr 22, 2012I 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]
View 5 Replies.net - Working Of Tcpclient Sockets In .net?
Jun 2, 2011I 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, 2010I'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?

Jun 8, 2012I am making a contact management program that works like a chat conversation. First, the client connects with his/her name and says: GIVE_INFO.

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].......

View 2 RepliesGet Accurate Amount Uploaded With TCPClient
Jan 3, 2011I'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.
