Connection STATE Problem

[Madz]

Dear

 

I am not getting an idea about how to handel this. i have a client server program, in which server listens for connections and client connects to server

When a PC starts with client software it connects to server and in server list box it shows the avaiable list of connected clients.

 

now here is a problem, if we close the server software and reopen the exe file we are unable to see list of clients which are connected

 

on client it have tried to do this in timer that if server has closed the connections after every 3 seconds client try to check the status of connection

 

if not cntoServer.state <> sckConnected then

 

cntoServer.connect

 

end if

 

but it cause a run time error.

 

can any one have any idea.

What is cntoServer? Do you use TCPListener and TCPClient or COM Winsock control?

[Fanell]

You are telling the program this: 'If you are connected, connect.' That makes no sense. :)

 

Should be like this.

 

If cntoServer.state <> sckConnected then

 

cntoServer.Connect

 

End if

 

 

Or:

 

If Not cntoServer.state = sckConnected Then

 

cntoServer.Connect

 

End If

 

 

<> mean Not Equal To

 

Good Luck.

Hello Dudes you have not checked my Coding i have written

 

IF NOT cn.state = sckconnected

 

Any how I have solved the problem using TCPCLIENT in normal it do not tell it's state i have to use it's protected property ACTIVE

i made a class

Imports System.Net.Sockets
Public Class mClient
   Inherits TcpClient
   Public Property Connected() As Boolean
       Get
           If Me.Active = True Then
               Return True
           Else
               Return False
           End If
       End Get
       Set(ByVal Value As Boolean)

       End Set
   End Property
End Class 

 

no i can check it as

 

if Client.active = then

try to connect it

else

exit sub

end if
