winsock connect-disconnect prob

1. I'm working on a little app, containing a server side and a client side. The clients must be able to connect and disconnect, and connect again.
The first connect works fine, but after disconnecting, a second connect seems impossible, I keep getting the 'adress in use' error on the client side.

to connect I use : tcpclient.connect <hostname> <port>
to disconnect : tcpclient.close

anyone got a clue ?

2. I test this app with two clients on one machine. But it seems that when I let the server send something to all connected clients, it only gets to the last connected client. I read in some news groups that this prob is known, and that it should work fine when using it in a real network setup. Can anyone confirm this ?

Tnx
Christophe VG

Bugs, don't ya just hate em?

The workaround:  Use a control array.

On the server side, when you accept a new socket, create a new socket by loading another object instance of the winsock control (Load tcpSocket(Index)) and accepting the connection with it, when it disconnects, you set it to nothing and unload it (Unload tcpSocket(Index)).

On the client side, draw socket1(0) on a form, but don't use it, load socket1(1) and use it til you disconnect, then unload it.  Repeat as necessary!
