Is there a way to send and recieve TCP/IP broadcast packets using API's? I have VB6 Enterprise Edition if that is of any useful information. Thanks in advance for any and all help.

Sending and Recieving Broadcast Packets
You can send UDP broadcast packets using Winsock APIs. You have to bind to a port and set the address to IP_ADDRESS_ANY constant. When you send message using the socket created in this fashion, the message is broadcast over the network and all the listeners on that port will receive the message.

Thanks for that information. I'm not sure of the APIs I would need to send UDP broadcast packets, do you know of an example of this technique or a list of the APIs needed? Also, would you happen to know how to listen for UDP broadcast packets? Thanks for the help.

Hi
You can easily use winsock.ocx for sending UDP packets to for example 200.200.200.255 ( subnet is 255.255.255.0 ) . If you need I will send you a small snippet.
