Hi

i am new to .net and i am planning to start working on a Client/Server application.

now i have heard of 2 classes that can be used as server for listening

TCPListener and Socket class(async), which one is better and easier? and is there a good tutorial for creating a server/client apps in vb.net?

 

thanks

TCPListner and TCPClient give a very easy to use implementation for a networked application. They provide a Stream interface so they can be used just like File I/O under .Net.

Using the socket class involves more work but gives you finer control over how things work and also provides asynchronous capabilities - which could give much better performance in production code.

IIRC there is a simple client/server chat program installed as sample when you do a VS install - just can't rememberer where it is though :confused:

yeah i found it thanks... and its a pretty good example..

one question tho: is there a limitation for the tcplistenter like the maximum number of connections it can take? and why is using the socket class better than tcpListener?

 

thanks again

hi

i got my own server working in vb.net using Socket class not TcpClient...

not we all know that Socket class uses async mode to handle everything..

 

how can i use OOP to be able to save each socket i receieve a connection in a collection and be able to loop through them when i want to broadcast?

 

thanks again

How are you opening the incoming connections on the server? If you are just using the .Accept method on a socket then you could always just add the returned socket to a collection.

 

If you post the server's code for handling incoming connections then it will be a bit easier to see how you are currently doing things.

there ya go

i am using BeginAccept and EndAccept

   Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
       Me.Visible = True
       NewThread = New Threading.Thread(AddressOf Listen)
       NewThread.Start()
   End Sub
   Private Sub Listen()
       Dim EP As New IPEndPoint(IPAddress.Any, 3600)
       Socket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
       Try
           TextBox1.Text += "Started Listening" & vbCrLf
           Socket.Bind(EP)
           Socket.Listen(1000)
           While True
               AllDone.Reset()
               Socket.BeginAccept(New AsyncCallback(AddressOf NewConnection), Socket)
               AllDone.WaitOne()
           End While

       Catch ex As Exception
           MsgBox(ex.ToString)
       End Try
   End Sub

its derived from MSDN socket class documentation

i wanna use this code to be able to create a class with it and the rest of the events so that i will be able to store all these instances in a collection or a hashtable.

 

thanks for ur help
