Multiple Winsock controls accepting connections

[half_eaten]

Hi, I've made a few web servers in the past, and all worked prefectly, minus one critical problem... whenever it would receive more than one connection at a time, it would cancel any current connections and begin the new one. I don't know why, I had 1025 winsock controls.

Now I am programming a new one that I am determined to get working perfectly, and I think I need some help with that problem. Here's the code I used to use to accept connections:

Private Sub ListenSock_ConnectionRequest(ByVal requestID As Long)
 
For FindOpenSock = 0 to 1024
     If Sock(FindOpenSock).State = sckClosed Then
          Sock(FindOpenSock).Accept requestID
          ListenSock.Close
          ListenSock.Listen
          Exit Sub
     End If
Next FindOpenSock
 
End Sub

I mean it looks like it should be fine to me, but it always screws up. BIG THANKS IN ADVANCE!!!

ListenSock.Close closed the current one, and opened with the next open number

ListenSock.Close closed the current one, and opened with the next open number

How do I keep the listening socket open after opening a new connection then? Do I need to just get rid of ListenSock and start with Sock(0) listening and then when it opens, change the listening port to Sock(1) etc??

thanks!

Sock(0) will give you an open port.

Get rid of ListenSock and listen on Sock(0). Accept the connection on any of Sock(1) through Sock(1024) that is closed.

Private Sub Sock_ConnectionRequest(Index As Integer, ByVal requestID As Long)
   If Index = 0 Then
      For FindOpenSock = 1 to 1024
           If Sock(FindOpenSock).State = sckClosed Then
              Sock(FindOpenSock).LocalPort = 0
              Sock(FindOpenSock).Accept requestID
              Exit Sub
           End If
      Next FindOpenSock
   End If
End Sub

Here is a link to the MS example of using the Winsock control: http://msdn.microsoft.com/library/de...ockcontrol.asp The example for multiple connections is towards the end of the article.
