Event for handling exception during Application Close in winforms

[Rashmi_Karnam]

We have developed winform application in C#. Here when user logout we are storing logout time in database. Right now we have a code written in formclosing event for updating logout time. But if any error occurs while application is running / if we kill process from windows task manager then its not updating logout time. So please can any one suggest whats the best way to update logout time in Database. Because next time when user enters into application we are displaying message that "you are already logged in (System Name)system. Please logout!" . So if application is closed and logout time is not saved then user will get this message. So we want to update even if any exception in app / closed intentionally from task manager. Is there any event to handle this??? Please reply its very urgent..... :confused:

I don’t think that this (killing the application from Task Manager) can be handled with in the application itself. And in fact, there can be n number of scenarios like this: • What if I Shut Down my computer. • What if there is hard disk crash.

Solution 1. Create a timer thread, that will send message if you dont get message application is dead . 2. Trace the Process of the application , if you dont find the process the application is dead ( this has to be done from other process , so u have 2 process )
