Update Database if Application Close unexpectedly in c# winforms -


i developing desktop based winform in c#. application may closed unexpectedly (power failure or debug mode off). in closing condition need update database . i.e. need change online status 1 0 how this?

the best way know whether application has died not try think of way update database when application closes; rather, create "session" record whenever application opened; "ping" record (i.e. there's lastpingutc column) every minute.

if application closes whatever reason, lastpingutc value on 1 minute ago , therefore can assume application / session dead.

actually, i'd assume given session dead after 5 minutes updating column may delayed.
