I am using Unolibs library in my client-server applcation, the problem is that how can i know if a client lost its connection.I am using the send method in order for my server to detect incoming client and its IP will be listed in a listview. Is looping in the listview then send msg to data client and if it failed using catch ex.contains "remote ip" then removing the current listview item,ok? Or is there any other method that is much easier and less memory consuming.
