VS 2008 Specify An IP Address For TcpClient To Use Through Lans

May 17, 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)

.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 2008 : Use The DHCP API To Retrieve A Computer's MAC Address When Given The IP Address?

Nov 27, 2009

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.

Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean

vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

VS 2008 - Properly Closing TCPClient So Server Does Not Crash

Jan 27, 2011

I have a simple tcpclient/server messenger running. Everything works great, except for when a client exits the software. When someone exits, is crashes the server with various exceptions and the server has to be restarted, as well as the clients. What I am looking for is a way to properly "log out" a client BUT leave any other connected client on so that is no break in the chat. Then the person that logged out or a new person can join back in whenever they choose.

CLIENT
''CHAT SERVICE
Dim clientSocket As New System.Net.Sockets.TcpClient()
Dim serverStream As NetworkStream
Dim readData As String
Dim infiniteCounter As Integer

[2008] Use The Tcplistener And Tcpclient Classes : Remove Whitespace?

Feb 2, 2009

I am trying to learn how to use the tcplistener and tcpclient classes. While I am attempting to compare something that is sent from the client to the server it seems that it adds a bunch of spaces, the reason I know that is if I write to the console what was sent it adds a bunch of spaces at the end. Is there anyway to get rid of it and just get the original text. I tried trim() but that didn't seem to work but I could have been using it improperly.

VS 2008 Create A Client / Server Chatroom Using TCPClient In Visual Basic

Jan 6, 2010

However 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).

VS 2008 (TcpClient) User/User Connection Circular Reference?

Aug 22, 2010

I have multiple TcpClient connections to my program. The connections exist as instances of a UserConnection class, that fires events on logon attempt and when receiving messages. My program also holds a Users object, which is a list of a User class objects, holding saved data (username, password etc) for each user that is allowed to log in.

It seems convenient to put a reference object of the respective user, in the UserConnection class (when successful login is verified). Hence, when an event is raised by the connection, the connection object will hold the user reference. As any event handler logic will need to know which user is responsible for the event.

If I don't make a user reference in the UserConnection class, then I need to loop through the users (less than 20) each time, to find the correct user. Not a big deal maybe, but i'm looking to understand how it would be done by an experienced programmer.

When data needs to be sent to a user, I need to access a UserConnection object. Hence the User class also holds a reference to the UserConnection class.
