I have made an Instant Messenger program in Visual Basic 6, i use it on my lan to communicate between my laptop and desktop in seperate parts of the house. I was wondering if there was anyway i would be able to get a list of 'Computer Names' and 'IP Address's' to be displayed so that i can connect to them easily.
The program uses Winsock to send and receive data, but i want to create a sort of 'User List' to see which computers are connected to the network, so that i can easily send them a message without checking what there IP is and whether the computer is connected.
I am also looking to expand it so that i can receive multiple connections, if anyone could give me an example on how to do this, that would be great.
I had an idea that i could somehow query the Subnet Mask, and find out what computers are in my workgroup but i do not know how to do this, would i have to ping every computer, every five minutes to check if its online or something similiar to this?
Any help would be great,
Thanks,
James
