msg on live system

i have build a system that working live at different PCS.

i need that if i want to send a message to all users..how can i do it???

using timer control or winsock control etc...

thanks

using the winsock control.. just have it "listen" you should not need a timer control.
once listening, you wait for the connection request.. then connect. recieve the message.. display it.. close the connection.. then listen again.

there are many tutorials around.. just do some searching :)

thanks dear,
but if i use winsock control then i need to install it at all clients....

currently .. i copy the application on server and map the drive on other clients and install some neccessary activex controls at all the clients..

is there any way to handle it through server. i don't want to install activex at all clietns.

thanks
