As Tracy said, yes. A socket is just a network connection. Your flex XMLSocket doesn't know or care what language the program listening on the other was written in. A socket connection is like a call connected between two telephones - if no-one at either end talks or neither end understands the other nothing much will happen. It's up to you to make conversation by defining how you will pass messages back and forth and how you will process them at either end.

I am not sure myself about my question :).
First, can Flex be listening to a socket that is created within
any program? I mean, if a vb program creates a socket using
Winsock will Flex be able to listen to such socket?
Second, if yes, how would data actually be transfered?
