Hi there,

Please let me know the details of it.
Thanking you

I think you want to use Winsock....This is what most chat programs use, some FTP....

Yes, I would suggest 2 methods:

1) Having both PCs connected to the Internet and then use winsocks to send data.

2) Much harder, do a direct dial using the RAS API's and then have a direct connection.
