What about TServerSocket and TClientSocket that come with Delphi? Simply set up a TCP/IP connection between your two programs...
Should be a breeze... You'll probably have to liaise with your client over which port you use if there's a firewall in the middle somewhere. You'll still need either a hostname (www.mydomain.com) or a fixed IP address of the machine on which your "commander" program is running. Resolving the domain name would probably ensure that the two machines are on the internet anyway. HTH, CoNOr ;-) -----Original Message----- From: Alistair George [mailto:[EMAIL PROTECTED] Thanks to Conner for suggesting Ping which works, but the specs (I just found) require that the clients program interrogates the commanders program to determine if both programs are running and connected to the net. EG, say you were a user of my program, and had it running and you were connected to the net, I (as the commander) could determine your programs availability, or vice-versa. In other words I'm not speaking of an internetwww., but a computer with a program running, and if its connected. _______________________________________________ Delphi mailing list [EMAIL PROTECTED] http://ns3.123.co.nz/mailman/listinfo/delphi
