Checks the existence of socket.
Notes:
  • To check the connection validity, use SocketClientInfo to check the IP address of client socket and the port number.
  • The socket exists as long as the created socket was not closed by SocketClose.
  • If the communication is interrupted, SocketExist may still return a positive result even if the dialog is stopped.
Example
// Check the existence before the creation
IF SocketExist("MySocket") = False THEN
IF SocketCreate("MySocket", 8000) = False THEN
 Error("Creation error" + ErrorInfo(errMessage))
 END
ELSE
 SocketRead("MySocket", False)
END
