You need to use Winsock. For a sample on how to use it ( client or server sides ) you can see Larry Miller's example at:

>Hi, all;
>I'm trying to write application, which should accept data feed through TCP/IP protocol on the pre-defined port and, after massaging data, should send data using another port. Any idea, in what direction should I look? Does VFP has anything embedded to handle such task? How can I tell my app what port listen to?
