Hi... I have 5 computers connected on a local network and Would like to send a message to all computers connected on my local network or send to selected computers.
All computers will have the program installed on.

Does anyone can send me an example of how I can do that?

Thanks, Alexandre

for win9* you can the mailslot components to send popup messages as winpop does here is url and they come with a demo: 

for an nt example you can use the nt messenger service :
"Application for sending messages through the network, using NT Messenger Service."

or alternatively you could use the ics or indy components.
they both have many client / server demos etc..

Definitely Mailslots. I've literally just finished writing a header file for Mailslots and little client and server apps that can talk to each other across the network using the mailslot, without the need for a component.

You could use "net send" for your purpose.
F.e. if the computer to receive has the IP ""
then the message must look like:
"net send HI!"
If its name is "FirstOne"
then the message must look like:
"net send FirstOne HI!"
All the messages are sent from NT and could be received
on both NT and 9x.
To send the messages from 9x you can use winpopup
(as it's already said above).
