Hello zayin, I tried same sample as Wilfried and its OK for me.
Are you sure your port was not in use at the time you tried to start the program ? "netstat -an" will show you all opened/listening port. if none is listening on your port then you application should "listen". regards. >>Did you try the code that I have posted? z> Yes, copy and paste with: z> ...raised exception ESocketException with message Error 10049 in function z> bind address not available. z> Changing the ip address or port does not change the error.
