Still have problems TCPlisnet

[jorge]

ok, ive been having a lot of problems lataly, with somthing, and try loads of stuff like thread and so on, but still no luck
So i set up a server that need to listen for connection, in background if posible so i can still have a form visible, but i wandta start and stop button on the form that will start/stop the server, can some one help me out?
Ive tryed thread as i said befor, but there is the stop/start problem agen , same goes for services
here is what i have:

Setup server
    Public ApacheMon_Server_thread As New System.Threading.Thread(AddressOf Server)
    Dim port As Int32 = sApache_server_port
    Public ApacheMon_Server As New TcpListener(port)
    Dim bytes(1024) As [Byte]
    Dim data As [String] = Nothing
    Dim client As TcpClient
    Public Sub Server()
        ApacheMon_Server.Start()
        client = ApacheMon_Server.AcceptTcpClient()
        Connection is made
        data = Nothing
        Dim stream As NetworkStream = client.GetStream()
        Dim i As Int32
        i = stream.Read(bytes, 0, bytes.Length)
        While (i <> 0)
            Dim sRetdate As String
            data = System.Text.Encoding.ASCII.GetString(bytes, 0, i)
            If ([String].Format(data)).ToLower = sApache_server_user.ToLower & ":" & sApache_server_pass.ToLower & "@" & "start" Then
                Retval = Shell(sApache_dir + "/bin/apache.exe -k start -n """ & sApache_service & """ ", AppWinStyle.Hide)
                sRetdate = "[" & Date.Now.Hour & ":" & Date.Now.Minute & ":" & Date.Now.Second & "]The remote Apache server has started."
            ElseIf ([String].Format(data)).ToLower = sApache_server_user.ToLower & ":" & sApache_server_pass.ToLower & "@" & "restart" Then
                Retval = Shell(sApache_dir + "/bin/apache.exe -k restart -n """ & sApache_service & """ ", AppWinStyle.Hide)
                sRetdate = "[" & Date.Now.Hour & ":" & Date.Now.Minute & ":" & Date.Now.Second & "]The remote Apache server has restarted."
            ElseIf ([String].Format(data)).ToLower = sApache_server_user.ToLower & ":" & sApache_server_pass.ToLower & "@" & "stop" Then
                Retval = Shell(sApache_dir + "/bin/apache.exe -k stop -n """ & sApache_service & """ ", AppWinStyle.Hide)
                sRetdate = "[" & Date.Now.Hour & ":" & Date.Now.Minute & ":" & Date.Now.Second & "]The remote Apache server has stopped."

            Else
                sRetdate = "[" & Date.Now.Hour & ":" & Date.Now.Minute & ":" & Date.Now.Second & "]Wrong username and/or password"
            End If
            Dim msg As [Byte]() = System.Text.Encoding.ASCII.GetBytes(sRetdate)
            stream.Write(msg, 0, msg.Length)
            client.Close()
            Exit While
        End While
    End Sub

The problem whit this is, that it will end the program once it is done, or if i remove the Exit While, it will well stop resonding!

any help would be greatly apriciated!

Should the Read function be in the loop because otherwise youre just processing the same thing over and over?

 

[jorge]

Dont realy know, got most of it from msdn, and i have no id what a loop is

 

[jorge]

I do know what it is suposed to do:
Start to listen on port xx
Wait for a connection,
if it get a connection,
Read the data that was send, if the date = x then do z
en when it done send a respons and returen to wait for a new connection

 

[AndreRyan]

The function accepts one connection, reads data then runs through one piece of information, closes the socket and crashes

 

[jorge]

yes, that about it lol,
So how can i stop it from crasing whne it done and then go back and listen for a new connection?
