You want to mean , that you need to show all the user list that are currently logged in into your application ?

do you really want this in your web application. Bcos we often need this for Windows Application. For windows use: System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged += new System.Net.NetworkInformation.NetworkAvailabilityChangedEventHandler(NetWorkChangedCallback);

If it is a web application (not intranet) then obviously the user is connected to internet. :)

This has to be the dumbest thing I have ever heard. If you're on a LAN and you want to know if an internet connection exists or not, just ping google or microsoft and if you get a reply or not, you'll know if you're online.

Yes Christian is Right. For web application, just make an object of XMLHttpRequest and do an AJAX call to any page using SetInterval, so that this ajax call will occur after a certain time. And show the status message based on the reply from the server. Thats all is possible in WEB... :cool::cool:
